It is predominantly nuclear. SNPs in IGF2BP2 gene are implicated in susceptibility to type 2 diabetes. IGF2BP2 plays an important role in cellular motility; it regulates the expression of PINCH-2, an important mediator of cell adhesion and motility, and MURF-3, a microtubule-stabilizing protein, through direct binding to their mRNAs. IGF2BP2 may be involved in the regulation of mRNA stability through the interaction with the AU-rich element-binding factor AUF1. In addition, IGF2BP2 binds initially to nascent beta-actin transcripts and facilitates the subsequent binding of the shuttling IGF2BP1. IGF2BP2 contains four hnRNP K-homology (KH) domains, two RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains), and a RGG RNA-binding domain.

RNA recognition motif 2 (RRM2) found in vertebrate insulin-like growth factor 2 mRNA-binding protein 1 (IGF2BP1); This subgroup corresponds to the RRM2 of IGF2BP1 (IGF2 mRNA-binding protein 1 or IMP-1), also termed coding region determinant-binding protein (CRD-BP), or VICKZ family member 1, or zipcode-binding protein 1 (ZBP-1). IGF2BP1 is a multi-functional regulator of RNA metabolism that has been implicated in the control of aspects of localization, stability, and translation for many mRNAs. It is predominantly located in cytoplasm and was initially identified as a trans-acting factor that interacts with the zipcode in the 3'- untranslated region (UTR) of the beta-actin mRNA, which is important for its localization and translational regulation. It inhibits IGF-II mRNA translation through binding to the 5'-UTR of the transcript. IGF2BP1 also acts as human immunodeficiency virus type 1 (HIV-1) Gag-binding factor that interacts with HIV-1 Gag protein and blocks the formation of infectious HIV-1 particles. It promotes mRNA stabilization and functions as a coding region determinant (CRD)-binding protein that binds to the coding region of betaTrCP1 mRNA and prevents miR-183-mediated degradation of betaTrCP1 mRNA. It also promotes c-myc mRNA stability by associating with the CRD. It stabilizes CD44 mRNA via interaction with the 3'-UTR of the transcript. In addition, IGF2BP1 specifically interacts with both Hepatitis C virus (HCV) 5'-UTR and 3'-UTR, further recruiting eIF3 and enhancing HCV internal ribosome entry site (IRES)-mediated translation initiation via the 3'-UTR. IGF2BP1 contains four hnRNP K-homology (KH) domains, two RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains), and a RGG RNA-binding domain. It also contains two putative nuclear export signals (NESs) and a putative nuclear localization signal (NLS).

K homology (KH) RNA-binding domain, type I; KH binds single-stranded RNA or DNA. It is found in a wide variety of proteins including ribosomal proteins, transcription factors and post-transcriptional modifiers of mRNA. There are two different KH domains that belong to different protein folds, but they share a single KH motif. The KH motif is folded into a beta alpha alpha beta unit. In addition to the core, type II KH domains (e.g. ribosomal protein S3) include an N-terminal extension and type I KH domains (e.g. hnRNP K) contain a C-terminal extension. Some KH-I superfamily members contain a divergent KH domain that lacks the RNA-binding GXXG motif. Some others have a mutated GXXG motif which may or may not have nucleic acid binding ability.

It acts as an RNA-binding factor that may recruit target transcripts to cytoplasmic protein-RNA complexes (mRNPs). It also modulates the rate and location at which target transcripts encounter the translational apparatus and shields them from endonuclease attacks or microRNA-mediated degradation. IGF2BP3 binds to the 3'-UTR of CD44 mRNA and stabilizes it, hence promotes cell adhesion and invadopodia formation in cancer cells. It also binds to beta-actin/ACTB and MYC transcripts. IGF2BP3 can form homooligomers and heterooligomers with IGF2BP1 and IGF2BP2 in an RNA-dependent manner. IGF2BP3 contains four K-homology (KH) RNA-binding domains which are important in RNA binding and are known to be involved in RNA synthesis and metabolism. The model corresponds to the fourth one.

FUBP1, also called FBP, or FUSE-binding protein 1, or DNA helicase V, or DH V, binds RNA and single-stranded DNA (ssDNA) and may act both as activator and repressor of transcription. It regulates MYC expression by binding to a single-stranded far-upstream element (FUSE) upstream of the MYC promoter. FUBP2, also called FUSE-binding protein 2, or KH type-splicing regulatory protein (KSRP), or p75, is a single-strand nucleic acid binding protein implicated in a variety of cellular processes, including splicing in the nucleus, mRNA decay, maturation of miRNA, and transcriptional control of proto-oncogenes such as c-myc. It regulates the stability and/or translatability of many mRNA species, encoding immune-relevant proteins, either by binding to AU-rich elements (AREs) of mRNA 3'UTR or by facilitating miRNA biogenesis to target mRNA. FUBP3, also called FUSE-binding protein 3, or MARTA2, was previously shown to mediate dendritic targeting of MAP2 mRNA in neurons. It may interact with single-stranded DNA from the far-upstream element (FUSE) and activate gene expression. It is required for beta-actin mRNA localization. It also interacts with fibroblast growth factor 9 (FGF9) 3'-UTR UG repeats and positively controls FGF9 expression through increasing translation of FGF9 mRNA. FUBP proteins contain four K-homology (KH) RNA-binding domains. The model corresponds to the first one.

first type I K homology (KH) RNA-binding domain found in the FUBP family RNA/DNA-binding proteins; The far upstream element-binding protein (FUBP) family includes FUBP1-3. FUBP1, also called FBP, or FUSE-binding protein 1, or DNA helicase V, or DH V, binds RNA and single-stranded DNA (ssDNA) and may act both as activator and repressor of transcription. It regulates MYC expression by binding to a single-stranded far-upstream element (FUSE) upstream of the MYC promoter. FUBP2, also called FUSE-binding protein 2, or KH type-splicing regulatory protein (KSRP), or p75, is a single-strand nucleic acid binding protein implicated in a variety of cellular processes, including splicing in the nucleus, mRNA decay, maturation of miRNA, and transcriptional control of proto-oncogenes such as c-myc. It regulates the stability and/or translatability of many mRNA species, encoding immune-relevant proteins, either by binding to AU-rich elements (AREs) of mRNA 3'UTR or by facilitating miRNA biogenesis to target mRNA. FUBP3, also called FUSE-binding protein 3, or MARTA2, was previously shown to mediate dendritic targeting of MAP2 mRNA in neurons. It may interact with single-stranded DNA from the far-upstream element (FUSE) and activate gene expression. It is required for beta-actin mRNA localization. It also interacts with fibroblast growth factor 9 (FGF9) 3'-UTR UG repeats and positively controls FGF9 expression through increasing translation of FGF9 mRNA. FUBP proteins contain four K-homology (KH) RNA-binding domains. The model corresponds to the first one.

type I K homology (KH) RNA-binding domain found in Mask family proteins; The Mask family includes Drosophila melanogaster ankyrin repeat and KH domain-containing protein Mask, and its mammalian homologues Mask1/ANKHD1 and Mask2/ANKRD17. Mask, also called multiple ankyrin repeat single KH domain-containing protein, is a large ankyrin repeat and KH domain-containing protein involved in Drosophila receptor tyrosine kinase signaling. It acts as a mediator of receptor tyrosine kinase (RTK) signaling and may act either downstream of MAPK or transduce signaling through a parallel branch of the RTK pathway. Mask is required for the development and organization of indirect flight muscle sarcomeres by regulating the formation of M line and H zone and the correct assembly of thick and thin filaments in the sarcomere. Mask1/ANKHD1, also called HIV-1 Vpr-binding ankyrin repeat protein, or multiple ankyrin repeats single KH domain, or Hmask, is highly expressed in various cancer tissues and is involved in cancer progression, including proliferation and invasion. Mask2/ANKRD17, also called ankyrin repeat protein 17, or gene trap ankyrin repeat protein (GTAR), or serologically defined breast cancer antigen NY-BR-16, is a ubiquitously expressed ankyrin factor essential for the vascular integrity during embryogenesis. It may be directly involved in the DNA replication process and play pivotal roles in cell cycle and DNA regulation. It is also involved in innate immune defense against bacteria and viruses.

second type I K homology (KH) RNA-binding domain found in Arabidopsis thaliana RNA-binding KH domain-containing protein PEPPER and similar proteins; The family includes a group of plant RNA-binding KH domain-containing proteins, such as PEPPER, flowering locus K homology domain protein (FLK), RNA-binding KH domain-containing protein RCF3 and KH domain-containing protein HEN4. PEPPER regulates vegetative and gynoecium development. It acts as a positive regulator of the central floral repressor FLOWERING LOCUS C. In concert with HUA2, PEPPER antagonizes FLK by positively regulating FLC probably at transcriptional and post-transcriptional levels, and thus acts as a negative regulator of flowering. FLK, also called flowering locus KH domain protein, regulates positively flowering by repressing FLC expression and post-transcriptional modification. PEPPER and FLK contain three K-homology (KH) RNA-binding domains. RCF3, also called protein ENHANCED STRESS RESPONSE 1 (ESR1), or protein HIGH OSMOTIC STRESS GENE EXPRESSION 5 (HOS5), or protein REGULATOR OF CBF GENE EXPRESSION 3, or protein SHINY 1 (SHI1), acts as negative regulator of osmotic stress-induced gene expression. It is involved in the regulation of thermotolerance responses under heat stress. It functions as an upstream regulator of heat stress transcription factor (HSF) genes. HEN4, also called protein HUA ENHANCER 4, plays a role in floral reproductive organ identity in the third whorl and floral determinacy specification by specifically promoting the processing of AGAMOUS (AG) pre-mRNA. It functions in association with HUA1 and HUA2. RCF3 and HEN4 contain five KH RNA-binding domains. The model corresponds to the KH2 domain of PEPPER and FLK, as well as KH2 and KH4 domains of RCF3 and HEN4.

first type I K homology (KH) RNA-binding domain found in Arabidopsis thaliana RNA-binding KH domain-containing protein PEPPER and similar proteins; The family includes a group of plant RNA-binding KH domain-containing proteins, such as PEPPER, flowering locus K homology domain protein (FLK), RNA-binding KH domain-containing protein RCF3 and KH domain-containing protein HEN4. PEPPER regulates vegetative and gynoecium development. It acts as a positive regulator of the central floral repressor FLOWERING LOCUS C. In concert with HUA2, PEPPER antagonizes FLK by positively regulating FLC probably at transcriptional and post-transcriptional levels, and thus acts as a negative regulator of flowering. FLK, also called flowering locus KH domain protein, regulates positively flowering by repressing FLC expression and post-transcriptional modification. PEPPER and FLK contain three K-homology (KH) RNA-binding domains. RCF3, also called protein ENHANCED STRESS RESPONSE 1 (ESR1), or protein HIGH OSMOTIC STRESS GENE EXPRESSION 5 (HOS5), or protein REGULATOR OF CBF GENE EXPRESSION 3, or protein SHINY 1 (SHI1), acts as negative regulator of osmotic stress-induced gene expression. It is involved in the regulation of thermotolerance responses under heat stress. It functions as an upstream regulator of heat stress transcription factor (HSF) genes. HEN4, also called protein HUA ENHANCER 4, plays a role in floral reproductive organ identity in the third whorl and floral determinacy specification by specifically promoting the processing of AGAMOUS (AG) pre-mRNA. It functions in association with HUA1 and HUA2. RCF3 and HEN4 contain five KH RNA-binding domains. The model corresponds to the KH1 domain of PEPPER and FLK, as well as KH1 and KH3 domains of RCF3 and HEN4.

sixth type I K homology (KH) RNA-binding domain found in vigilin and similar proteins; Vigilin, also called high density lipoprotein-binding protein, or HDL-binding protein, is a ubiquitous and highly conserved RNA-binding protein that shuttles between nucleus and cytoplasm presumably in contact with RNA molecules. It may be involved in chromosome partitioning at mitosis, facilitating translation and tRNA transport, and control of mRNA metabolism, including estrogen-mediated stabilization of vitellogenin mRNA. Vigilin is up-regulated by cholesterol loading of cells and functions to protect cells from over-accumulation of cholesterol. It may play a role in cell sterol metabolism. Disruption of human vigilin impairs chromosome condensation and segregation. Vigilin has a unique structure of 14-15 consecutively arranged, but non-identical K-homology (KH) domains which apparently mediate RNA-protein binding. The model corresponds to the sixth one.

fourth type I K homology (KH) RNA-binding domain found in the FUBP family RNA/DNA-binding proteins; The far upstream element-binding protein (FUBP) family includes FUBP1-3. FUBP1, also called FBP, or FUSE-binding protein 1, or DNA helicase V, or DH V, binds RNA and single-stranded DNA (ssDNA) and may act both as activator and repressor of transcription. It regulates MYC expression by binding to a single-stranded far-upstream element (FUSE) upstream of the MYC promoter. FUBP2, also called FUSE-binding protein 2, or KH type-splicing regulatory protein (KSRP), or p75, is a single-strand nucleic acid binding protein implicated in a variety of cellular processes, including splicing in the nucleus, mRNA decay, maturation of miRNA, and transcriptional control of proto-oncogenes such as c-myc. It regulates the stability and/or translatability of many mRNA species, encoding immune-relevant proteins, either by binding to AU-rich elements (AREs) of mRNA 3'UTR or by facilitating miRNA biogenesis to target mRNA. FUBP3, also called FUSE-binding protein 3, or MARTA2, was previously shown to mediate dendritic targeting of MAP2 mRNA in neurons. It may interact with single-stranded DNA from the far-upstream element (FUSE) and activate gene expression. It is required for beta-actin mRNA localization. It also interacts with fibroblast growth factor 9 (FGF9) 3'-UTR UG repeats and positively controls FGF9 expression through increasing translation of FGF9 mRNA. FUBP proteins contain four K-homology (KH) RNA-binding domains. The model corresponds to the fourth one.

RNA recognition motif 2 (RRM2) found in ribonucleoprotein PTB-binding raver-1, raver-2 and similar proteins; This subfamily corresponds to the RRM2 of raver-1 and raver-2. Raver-1 is a ubiquitously expressed heterogeneous nuclear ribonucleoprotein (hnRNP) that serves as a co-repressor of the nucleoplasmic splicing repressor polypyrimidine tract-binding protein (PTB)-directed splicing of select mRNAs. It shuttles between the cytoplasm and the nucleus and can accumulate in the perinucleolar compartment, a dynamic nuclear substructure that harbors PTB. Raver-1 also modulates focal adhesion assembly by binding to the cytoskeletal proteins, including alpha-actinin, vinculin, and metavinculin (an alternatively spliced isoform of vinculin) at adhesion complexes, particularly in differentiated muscle tissue. Raver-2 is a novel member of the heterogeneous nuclear ribonucleoprotein (hnRNP) family. It shows high sequence homology to raver-1. Raver-2 exerts a spatio-temporal expression pattern during embryogenesis and is mainly limited to differentiated neurons and glia cells. Although it displays nucleo-cytoplasmic shuttling in heterokaryons, raver2 localizes to the nucleus in glia cells and neurons. Raver-2 can interact with PTB and may participate in PTB-mediated RNA-processing. However, there is no evidence indicating that raver-2 can bind to cytoplasmic proteins. Both, raver-1 and raver-2, contain three N-terminal RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains), two putative nuclear localization signals (NLS) at the N- and C-termini, a central leucine-rich region, and a C-terminal region harboring two [SG][IL]LGxxP motifs. They binds to RNA through the RRMs. In addition, the two [SG][IL]LGxxP motifs serve as the PTB-binding motifs in raver1. However, raver-2 interacts with PTB through the SLLGEPP motif only.

It functions by binding to the 5' UTR of the insulin-like growth factor 2 (IGF2) mRNA and regulating IGF2 translation. It regulates localized beta-actin/ACTB mRNA translation, a crucial process for cell polarity, cell migration and neurite outgrowth. IGF2BP1 can form homodimers and heterodimers with IGF2BP1 and IGF2BP3. It contains four K-homology (KH) RNA-binding domains which are important in RNA binding and are known to be involved in RNA synthesis and metabolism. The model corresponds to the third one.

PEPPER regulates vegetative and gynoecium development. It acts as a positive regulator of the central floral repressor FLOWERING LOCUS C. In concert with HUA2, PEPPER antagonizes FLK by positively regulating FLC probably at transcriptional and post-transcriptional levels, and thus acts as a negative regulator of flowering. FLK, also called flowering locus KH domain protein, regulates positively flowering by repressing FLC expression and post-transcriptional modification. PEPPER and FLK contain three K-homology (KH) RNA-binding domains. RCF3, also called protein ENHANCED STRESS RESPONSE 1 (ESR1), or protein HIGH OSMOTIC STRESS GENE EXPRESSION 5 (HOS5), or protein REGULATOR OF CBF GENE EXPRESSION 3, or protein SHINY 1 (SHI1), acts as negative regulator of osmotic stress-induced gene expression.

RNA recognition motif (RRM) found in vertebrate RNA binding protein fox-1 homologs and similar proteins; This subfamily corresponds to the RRM of several tissue-specific alternative splicing isoforms of vertebrate RNA binding protein Fox-1 homologs, which show high sequence similarity to the Caenorhabditis elegans feminizing locus on X (Fox-1) gene encoding Fox-1 protein. RNA binding protein Fox-1 homolog 1 (RBFOX1), also termed ataxin-2-binding protein 1 (A2BP1), or Fox-1 homolog A, or hexaribonucleotide-binding protein 1 (HRNBP1), is predominantly expressed in neurons, skeletal muscle and heart. It regulates alternative splicing of tissue-specific exons by binding to UGCAUG elements. Moreover, RBFOX1 binds to the C-terminus of ataxin-2 and forms an ataxin-2/A2BP1 complex involved in RNA processing. RNA binding protein fox-1 homolog 2 (RBFOX2), also termed Fox-1 homolog B, or hexaribonucleotide-binding protein 2 (HRNBP2), or RNA-binding motif protein 9 (RBM9), or repressor of tamoxifen transcriptional activity, is expressed in ovary, whole embryo, and human embryonic cell lines in addition to neurons and muscle. RBFOX2 activates splicing of neuron-specific exons through binding to downstream UGCAUG elements. RBFOX2 also functions as a repressor of tamoxifen activation of the estrogen receptor. RNA binding protein Fox-1 homolog 3 (RBFOX3 or NeuN or HRNBP3), also termed Fox-1 homolog C, is a nuclear RNA-binding protein that regulates alternative splicing of the RBFOX2 pre-mRNA, producing a message encoding a dominant negative form of the RBFOX2 protein. Its message is detected exclusively in post-mitotic regions of embryonic brain. Like RBFOX1, both RBFOX2 and RBFOX3 bind to the hexanucleotide UGCAUG elements and modulate brain and muscle-specific splicing of exon EIIIB of fibronectin, exon N1 of c-src, and calcitonin/CGRP. Members in this family also harbor one RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains).

eighth type I K homology (KH) RNA-binding domain found in vigilin and similar proteins; Vigilin, also called high density lipoprotein-binding protein, or HDL-binding protein, is a ubiquitous and highly conserved RNA-binding protein that shuttles between nucleus and cytoplasm presumably in contact with RNA molecules. It may be involved in chromosome partitioning at mitosis, facilitating translation and tRNA transport, and control of mRNA metabolism, including estrogen-mediated stabilization of vitellogenin mRNA. Vigilin is up-regulated by cholesterol loading of cells and functions to protect cells from over-accumulation of cholesterol. It may play a role in cell sterol metabolism. Disruption of human vigilin impairs chromosome condensation and segregation. Vigilin has a unique structure of 14-15 consecutively arranged, but non-identical K-homology (KH) domains which apparently mediate RNA-protein binding. The model corresponds to the eighth one.

RNA recognition motif 3 (RRM3) found in CELF/Bruno-like family of RNA binding proteins CELF1, CELF2, CELF3, CELF4, CELF5, CELF6 and similar proteins; This subgroup corresponds to the RRM3 of the CUGBP1 and ETR-3-like factors (CELF) or BRUNOL (Bruno-like) proteins, a family of structurally related RNA-binding proteins involved in the regulation of pre-mRNA splicing in the nucleus and in the control of mRNA translation and deadenylation in the cytoplasm. The family contains six members: CELF-1 (also termed BRUNOL-2, or CUG-BP1, or NAPOR, or EDEN-BP), CELF-2 (also termed BRUNOL-3, or ETR-3, or CUG-BP2, or NAPOR-2), CELF-3 (also termed BRUNOL-1, or TNRC4, or ETR-1, or CAGH4, or ER DA4), CELF-4 (also termed BRUNOL-4), CELF-5 (also termed BRUNOL-5), CELF-6 (also termed BRUNOL-6). They all contain three highly conserved RNA recognition motifs (RRMs), also known as RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains): two consecutive RRMs (RRM1 and RRM2) situated in the N-terminal region followed by a linker region and the third RRM (RRM3) close to the C-terminus of the protein. The low sequence conservation of the linker region is highly suggestive of a large variety in the co-factors that associate with the various CELF family members. Based on both sequence similarity and function, the CELF family can be divided into two subfamilies, the first containing CELFs 1 and 2, and the second containing CELFs 3, 4, 5, and 6. The different CELF proteins may act through different sites on at least some substrates. Furthermore, CELF proteins may interact with each other in varying combinations to influence alternative splicing in different contexts.

FUBP1, also called FBP, or FUSE-binding protein 1, or DNA helicase V, or DH V, binds RNA and single-stranded DNA (ssDNA) and may act both as activator and repressor of transcription. It regulates MYC expression by binding to a single-stranded far-upstream element (FUSE) upstream of the MYC promoter. FUBP2, also called FUSE-binding protein 2, or KH type-splicing regulatory protein (KSRP), or p75, is a single-strand nucleic acid binding protein implicated in a variety of cellular processes, including splicing in the nucleus, mRNA decay, maturation of miRNA, and transcriptional control of proto-oncogenes such as c-myc. It regulates the stability and/or translatability of many mRNA species, encoding immune-relevant proteins, either by binding to AU-rich elements (AREs) of mRNA 3'UTR or by facilitating miRNA biogenesis to target mRNA. FUBP3, also called FUSE-binding protein 3, or MARTA2, was previously shown to mediate dendritic targeting of MAP2 mRNA in neurons. It may interact with single-stranded DNA from the far-upstream element (FUSE) and activate gene expression. It is required for beta-actin mRNA localization. It also interacts with fibroblast growth factor 9 (FGF9) 3'-UTR UG repeats and positively controls FGF9 expression through increasing translation of FGF9 mRNA. FUBP proteins contain four K-homology (KH) RNA-binding domains. The model corresponds to the third one.

RNA recognition motif 1 (RRM1) and 2 (RRM2) found in RRM-containing coactivator activator/modulator (CoAA) and similar proteins; This subfamily corresponds to the RRM in CoAA (also known as RBM14 or PSP2) and RNA-binding protein 4 (RBM4). CoAA is a heterogeneous nuclear ribonucleoprotein (hnRNP)-like protein identified as a nuclear receptor coactivator. It mediates transcriptional coactivation and RNA splicing effects in a promoter-preferential manner, and is enhanced by thyroid hormone receptor-binding protein (TRBP). CoAA contains two N-terminal RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains), and a TRBP-interacting domain. RBM4 is a ubiquitously expressed splicing factor with two isoforms, RBM4A (also known as Lark homolog) and RBM4B (also known as RBM30), which are very similar in structure and sequence. RBM4 may also function as a translational regulator of stress-associated mRNAs as well as play a role in micro-RNA-mediated gene regulation. RBM4 contains two N-terminal RRMs, a CCHC-type zinc finger, and three alanine-rich regions within their C-terminal regions. This family also includes Drosophila RNA-binding protein lark (Dlark), a homolog of human RBM4. It plays an important role in embryonic development and in the circadian regulation of adult eclosion. Dlark shares high sequence similarity with RBM4 at the N-terminal region. However, Dlark has three proline-rich segments instead of three alanine-rich segments within the C-terminal region.

type I K homology (KH) RNA-binding domain found in KHDC1-like family; The KHDC1-like family corresponds to a group of structurally related proteins characterized by an atypical RNA-binding KH domain. They are unique to eutherian mammals and specifically expressed in oocytes and/or embryonic stem cells. Family members include KH homology domain-containing protein 1 (KHDC1), KHDC1-like protein (KHDC1L), KHDC3-like protein (KHDC3L, also called ES cell-associated transcript 1 protein or ECAT1), developmental pluripotency-associated 5 protein (DPPA5, also called embryonal stem cell-specific gene 1 protein or ESG-1), Oocyte-expressed protein (OOEP, also called KH homology domain-containing protein 2 or KHDC2, or Oocyte- and embryo-specific protein 19 or OEP19). KHDC3L is essential for human oocyte maturation and pre-implantation development of the resulting embryos. DPPA5 is involved in the maintenance of embryonic stem (ES) cell pluripotency. OOEP plays an essential role for zygotes to progress beyond the first embryonic cell divisions.

RNA recognition motif 3 (RRM3) found in the Hu proteins family; This subfamily corresponds to the RRM3 of the Hu proteins family which represent a group of RNA-binding proteins involved in diverse biological processes. Since the Hu proteins share high homology with the Drosophila embryonic lethal abnormal vision (ELAV) protein, the Hu family is sometimes referred to as the ELAV family. Drosophila ELAV is exclusively expressed in neurons and is required for the correct differentiation and survival of neurons in flies. The neuronal members of the Hu family include Hu-antigen B (HuB or ELAV-2 or Hel-N1), Hu-antigen C (HuC or ELAV-3 or PLE21), and Hu-antigen D (HuD or ELAV-4), which play important roles in neuronal differentiation, plasticity and memory. HuB is also expressed in gonads. Hu-antigen R (HuR or ELAV-1 or HuA) is the ubiquitously expressed Hu family member. It has a variety of biological functions mostly related to the regulation of cellular response to DNA damage and other types of stress. Hu proteins perform their cytoplasmic and nuclear molecular functions by coordinately regulating functionally related mRNAs. In the cytoplasm, Hu proteins recognize and bind to AU-rich RNA elements (AREs) in the 3' untranslated regions (UTRs) of certain target mRNAs, such as GAP-43, vascular epithelial growth factor (VEGF), the glucose transporter GLUT1, eotaxin and c-fos, and stabilize those ARE-containing mRNAs. They also bind and regulate the translation of some target mRNAs, such as neurofilament M, GLUT1, and p27. In the nucleus, Hu proteins function as regulators of polyadenylation and alternative splicing. Each Hu protein contains three RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains). RRM1 and RRM2 may cooperate in binding to an ARE. RRM3 may help to maintain the stability of the RNA-protein complex, and might also bind to poly(A) tails or be involved in protein-protein interactions.

It acts as an RNA-binding factor that may recruit target transcripts to cytoplasmic protein-RNA complexes (mRNPs). It also modulates the rate and location at which target transcripts encounter the translational apparatus and shields them from endonuclease attacks or microRNA-mediated degradation. IGF2BP3 binds to the 3'-UTR of CD44 mRNA and stabilizes it, hence promotes cell adhesion and invadopodia formation in cancer cells. It also binds to beta-actin/ACTB and MYC transcripts. IGF2BP3 can form homooligomers and heterooligomers with IGF2BP1 and IGF2BP2 in an RNA-dependent manner. IGF2BP3 contains four K-homology (KH) RNA-binding domains which are important in RNA binding and are known to be involved in RNA synthesis and metabolism. The model corresponds to the first one.

RNA recognition motif 2 (RRM2) found in Nicotiana sylvestris chloroplastic 33 kDa ribonucleoprotein (NsCP33) and similar proteins; The family includes NsCP33, Arabidopsis thaliana chloroplastic 31 kDa ribonucleoprotein (CP31A) and mitochondrial glycine-rich RNA-binding protein 2 (AtGR-RBP2). NsCP33 may be involved in splicing and/or processing of chloroplast RNA's. AtCP31A, also called RNA-binding protein 1/2/3 (AtRBP33), or RNA-binding protein CP31A, or RNA-binding protein RNP-T, or RNA-binding protein cp31, is required for specific RNA editing events in chloroplasts and stabilizes specific chloroplast mRNAs, as well as for normal chloroplast development under cold stress conditions by stabilizing transcripts of numerous mRNAs under these conditions. CP31A may modulate telomere replication through RNA binding domains. AtGR-RBP2, also called AtRBG2, or glycine-rich protein 2 (AtGRP2), or mitochondrial RNA-binding protein 1a (At-mRBP1a), plays a role in RNA transcription or processing during stress. It binds RNAs and DNAs sequence with a preference to single-stranded nucleic acids. AtGR-RBP2 displays strong affinity to poly(U) sequence. It exerts cold and freezing tolerance, probably by exhibiting an RNA chaperone activity during the cold and freezing adaptation process. Some members in this family contain two RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains). The model corresponds to the second RRM motif.

first type I K homology (KH) RNA-binding domain found in the FUBP family RNA/DNA-binding proteins; The far upstream element-binding protein (FUBP) family includes FUBP1-3. FUBP1, also called FBP, or FUSE-binding protein 1, or DNA helicase V, or DH V, binds RNA and single-stranded DNA (ssDNA) and may act both as activator and repressor of transcription. It regulates MYC expression by binding to a single-stranded far-upstream element (FUSE) upstream of the MYC promoter. FUBP2, also called FUSE-binding protein 2, or KH type-splicing regulatory protein (KSRP), or p75, is a single-strand nucleic acid binding protein implicated in a variety of cellular processes, including splicing in the nucleus, mRNA decay, maturation of miRNA, and transcriptional control of proto-oncogenes such as c-myc. It regulates the stability and/or translatability of many mRNA species, encoding immune-relevant proteins, either by binding to AU-rich elements (AREs) of mRNA 3'UTR or by facilitating miRNA biogenesis to target mRNA. FUBP3, also called FUSE-binding protein 3, or MARTA2, was previously shown to mediate dendritic targeting of MAP2 mRNA in neurons. It may interact with single-stranded DNA from the far-upstream element (FUSE) and activate gene expression. It is required for beta-actin mRNA localization. It also interacts with fibroblast growth factor 9 (FGF9) 3'-UTR UG repeats and positively controls FGF9 expression through increasing translation of FGF9 mRNA. FUBP proteins contain four K-homology (KH) RNA-binding domains. The model corresponds to the first one.

type I K homology (KH) RNA-binding domain found in Mask family proteins; The Mask family includes Drosophila melanogaster ankyrin repeat and KH domain-containing protein Mask, and its mammalian homologues Mask1/ANKHD1 and Mask2/ANKRD17. Mask, also called multiple ankyrin repeat single KH domain-containing protein, is a large ankyrin repeat and KH domain-containing protein involved in Drosophila receptor tyrosine kinase signaling. It acts as a mediator of receptor tyrosine kinase (RTK) signaling and may act either downstream of MAPK or transduce signaling through a parallel branch of the RTK pathway. Mask is required for the development and organization of indirect flight muscle sarcomeres by regulating the formation of M line and H zone and the correct assembly of thick and thin filaments in the sarcomere. Mask1/ANKHD1, also called HIV-1 Vpr-binding ankyrin repeat protein, or multiple ankyrin repeats single KH domain, or Hmask, is highly expressed in various cancer tissues and is involved in cancer progression, including proliferation and invasion. Mask2/ANKRD17, also called ankyrin repeat protein 17, or gene trap ankyrin repeat protein (GTAR), or serologically defined breast cancer antigen NY-BR-16, is a ubiquitously expressed ankyrin factor essential for the vascular integrity during embryogenesis. It may be directly involved in the DNA replication process and play pivotal roles in cell cycle and DNA regulation. It is also involved in innate immune defense against bacteria and viruses.

fourteenth type I K homology (KH) RNA-binding domain found in vigilin and similar proteins; Vigilin, also called high density lipoprotein-binding protein, or HDL-binding protein, is a ubiquitous and highly conserved RNA-binding protein that shuttles between nucleus and cytoplasm presumably in contact with RNA molecules. It may be involved in chromosome partitioning at mitosis, facilitating translation and tRNA transport, and control of mRNA metabolism, including estrogen-mediated stabilization of vitellogenin mRNA. Vigilin is up-regulated by cholesterol loading of cells and functions to protect cells from over-accumulation of cholesterol. It may play a role in cell sterol metabolism. Disruption of human vigilin impairs chromosome condensation and segregation. Vigilin has a unique structure of 14-15 consecutively arranged, but non-identical K-homology (KH) domains which apparently mediate RNA-protein binding. The model corresponds to the fourteenth one.

RNA recognition motif 1 (RRM1) and 2 (RRM2) found in CELF/Bruno-like family of RNA binding proteins and plant flowering time control protein FCA; This subfamily corresponds to the RRM1 and RRM2 domains of the CUGBP1 and ETR-3-like factors (CELF) as well as plant flowering time control protein FCA. CELF, also termed BRUNOL (Bruno-like) proteins, is a family of structurally related RNA-binding proteins involved in regulation of pre-mRNA splicing in the nucleus, and control of mRNA translation and deadenylation in the cytoplasm. The family contains six members: CELF-1 (also known as BRUNOL-2, CUG-BP1, NAPOR, EDEN-BP), CELF-2 (also known as BRUNOL-3, ETR-3, CUG-BP2, NAPOR-2), CELF-3 (also known as BRUNOL-1, TNRC4, ETR-1, CAGH4, ER DA4), CELF-4 (BRUNOL-4), CELF-5 (BRUNOL-5) and CELF-6 (BRUNOL-6). They all contain three highly conserved RNA recognition motifs (RRMs), also known as RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains): two consecutive RRMs (RRM1 and RRM2) situated in the N-terminal region followed by a linker region and the third RRM (RRM3) close to the C-terminus of the protein. The low sequence conservation of the linker region is highly suggestive of a large variety in the co-factors that associate with the various CELF family members. Based on both, sequence similarity and function, the CELF family can be divided into two subfamilies, the first containing CELFs 1 and 2, and the second containing CELFs 3, 4, 5, and 6. The different CELF proteins may act through different sites on at least some substrates. Furthermore, CELF proteins may interact with each other in varying combinations to influence alternative splicing in different contexts. This subfamily also includes plant flowering time control protein FCA that functions in the posttranscriptional regulation of transcripts involved in the flowering process. FCA contains two RRMs, and a WW protein interaction domain.

They are single-stranded nucleic acid binding proteins that bind preferentially to oligo dC. They act as iron chaperones for ferritin. In case of infection by poliovirus, PCBP1 plays a role in initiation of viral RNA replication in concert with the viral protein 3CD. PCBP2 is a major cellular poly(rC)-binding protein. It also binds poly(rU). PCBP2 negatively regulates cellular antiviral responses mediated by MAVS signaling. It acts as an adapter between MAVS and the E3 ubiquitin ligase ITCH, therefore triggering MAVS ubiquitination and degradation. PCBP2 forms a metabolon with the heme oxygenase 1/cytochrome P450 reductase complex for heme catabolism and iron transfer. Both PCBP1 and PCBP2 contain three K-homology (KH) RNA-binding domains.

RNA recognition motif 2 (RRM2) found in the c-myc gene single-strand binding proteins (MSSP) family; This subfamily corresponds to the RRM2 of c-myc gene single-strand binding proteins (MSSP) family, including single-stranded DNA-binding protein MSSP-1 (also termed RBMS1 or SCR2) and MSSP-2 (also termed RBMS2 or SCR3). All MSSP family members contain two RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains), both of which are responsible for the specific DNA binding activity. Both, MSSP-1 and -2, have been identified as protein factors binding to a putative DNA replication origin/transcriptional enhancer sequence present upstream from the human c-myc gene in both single- and double-stranded forms. Thus they have been implied in regulating DNA replication, transcription, apoptosis induction, and cell-cycle movement, via the interaction with C-MYC, the product of protooncogene c-myc. Moreover, they family includes a new member termed RNA-binding motif, single-stranded-interacting protein 3 (RBMS3), which is not a transcriptional regulator. RBMS3 binds with high affinity to A/U-rich stretches of RNA, and to A/T-rich DNA sequences, and functions as a regulator of cytoplasmic activity. In addition, a putative meiosis-specific RNA-binding protein termed sporulation-specific protein 5 (SPO5, or meiotic RNA-binding protein 1, or meiotically up-regulated gene 12 protein), encoded by Schizosaccharomyces pombe Spo5/Mug12 gene, is also included in this family. SPO5 is a novel meiosis I regulator that may function in the vicinity of the Mei2 dot.

fourth type I K homology (KH) RNA-binding domain found in the FUBP family RNA/DNA-binding proteins; The far upstream element-binding protein (FUBP) family includes FUBP1-3. FUBP1, also called FBP, or FUSE-binding protein 1, or DNA helicase V, or DH V, binds RNA and single-stranded DNA (ssDNA) and may act both as activator and repressor of transcription. It regulates MYC expression by binding to a single-stranded far-upstream element (FUSE) upstream of the MYC promoter. FUBP2, also called FUSE-binding protein 2, or KH type-splicing regulatory protein (KSRP), or p75, is a single-strand nucleic acid binding protein implicated in a variety of cellular processes, including splicing in the nucleus, mRNA decay, maturation of miRNA, and transcriptional control of proto-oncogenes such as c-myc. It regulates the stability and/or translatability of many mRNA species, encoding immune-relevant proteins, either by binding to AU-rich elements (AREs) of mRNA 3'UTR or by facilitating miRNA biogenesis to target mRNA. FUBP3, also called FUSE-binding protein 3, or MARTA2, was previously shown to mediate dendritic targeting of MAP2 mRNA in neurons. It may interact with single-stranded DNA from the far-upstream element (FUSE) and activate gene expression. It is required for beta-actin mRNA localization. It also interacts with fibroblast growth factor 9 (FGF9) 3'-UTR UG repeats and positively controls FGF9 expression through increasing translation of FGF9 mRNA. FUBP proteins contain four K-homology (KH) RNA-binding domains. The model corresponds to the fourth one.

It shuttles between the cytoplasm and the nucleus and can accumulate in the perinucleolar compartment, a dynamic nuclear substructure that harbors PTB. Raver-1 also modulates focal adhesion assembly by binding to the cytoskeletal proteins, including alpha-actinin, vinculin, and metavinculin (an alternatively spliced isoform of vinculin) at adhesion complexes, particularly in differentiated muscle tissue. Raver-2 is a novel member of the heterogeneous nuclear ribonucleoprotein (hnRNP) family. It shows high sequence homology to raver-1. Raver-2 exerts a spatio-temporal expression pattern during embryogenesis and is mainly limited to differentiated neurons and glia cells. Although it displays nucleo-cytoplasmic shuttling in heterokaryons, raver2 localizes to the nucleus in glia cells and neurons. Raver-2 can interact with PTB and may participate in PTB-mediated RNA-processing. However, there is no evidence indicating that raver-2 can bind to cytoplasmic proteins. Both, raver-1 and raver-2, contain three N-terminal RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains), two putative nuclear localization signals (NLS) at the N- and C-termini, a central leucine-rich region, and a C-terminal region harboring two [SG][IL]LGxxP motifs. They binds to RNA through the RRMs. In addition, the two [SG][IL]LGxxP motifs serve as the PTB-binding motifs in raver1. However, raver-2 interacts with PTB through the SLLGEPP motif only.

second type I K homology (KH) RNA-binding domain found in insulin-like growth factor 2 mRNA-binding protein 3 (IGF2BP3) and similar proteins; IGF2BP3, also called IGF2 mRNA-binding protein 3 (IMP-3), or hepatocellular carcinoma autoantigen p62, or IGF-II mRNA-binding protein 3, or VICKZ family member 3 (VICKZ3), or KH domain-containing protein overexpressed in cancer, or KOC, is primarily found in the nucleolus, where it can bind to the 5' UTR of the insulin-like growth factor II leader 3 mRNA and may repress translation of insulin-like growth factor II during late development. It acts as an RNA-binding factor that may recruit target transcripts to cytoplasmic protein-RNA complexes (mRNPs). It also modulates the rate and location at which target transcripts encounter the translational apparatus and shields them from endonuclease attacks or microRNA-mediated degradation. IGF2BP3 binds to the 3'-UTR of CD44 mRNA and stabilizes it, hence promotes cell adhesion and invadopodia formation in cancer cells. It also binds to beta-actin/ACTB and MYC transcripts. IGF2BP3 can form homooligomers and heterooligomers with IGF2BP1 and IGF2BP2 in an RNA-dependent manner. IGF2BP3 contains four K-homology (KH) RNA-binding domains which are important in RNA binding and are known to be involved in RNA synthesis and metabolism. The model corresponds to the second one.

It may be involved in the nuclear metabolism of hnRNAs, particularly for pre-mRNAs that contain cytidine-rich sequences. It can also bind poly(C) single-stranded DNA. hnRNP K plays an important role in p53/TP53 response to DNA damage, acting at the level of both transcription activation and repression. hnRNP K contains three K-homology (KH) RNA-binding domains. The model corresponds to the second one.

fourth type I K homology (KH) RNA-binding domain found in the FUBP family RNA/DNA-binding proteins; The far upstream element-binding protein (FUBP) family includes FUBP1-3. FUBP1, also called FBP, or FUSE-binding protein 1, or DNA helicase V, or DH V, binds RNA and single-stranded DNA (ssDNA) and may act both as activator and repressor of transcription. It regulates MYC expression by binding to a single-stranded far-upstream element (FUSE) upstream of the MYC promoter. FUBP2, also called FUSE-binding protein 2, or KH type-splicing regulatory protein (KSRP), or p75, is a single-strand nucleic acid binding protein implicated in a variety of cellular processes, including splicing in the nucleus, mRNA decay, maturation of miRNA, and transcriptional control of proto-oncogenes such as c-myc. It regulates the stability and/or translatability of many mRNA species, encoding immune-relevant proteins, either by binding to AU-rich elements (AREs) of mRNA 3'UTR or by facilitating miRNA biogenesis to target mRNA. FUBP3, also called FUSE-binding protein 3, or MARTA2, was previously shown to mediate dendritic targeting of MAP2 mRNA in neurons. It may interact with single-stranded DNA from the far-upstream element (FUSE) and activate gene expression. It is required for beta-actin mRNA localization. It also interacts with fibroblast growth factor 9 (FGF9) 3'-UTR UG repeats and positively controls FGF9 expression through increasing translation of FGF9 mRNA. FUBP proteins contain four K-homology (KH) RNA-binding domains. The model corresponds to the fourth one.

RNA recognition motif (RRM) found in the Aly/REF family; This subfamily corresponds to the RRM of Aly/REF family which includes THO complex subunit 4 (THOC4, also termed Aly/REF), S6K1 Aly/REF-like target (SKAR, also termed PDIP3 or PDIP46) and similar proteins. THOC4 is an mRNA transporter protein with a well conserved RNA recognition motif (RRM), also termed RBD (RNA binding domain) or RNP (ribonucleoprotein domain). It is involved in RNA transportation from the nucleus, and was initially identified as a transcription coactivator of LEF-1 and AML-1 for the TCRalpha enhancer function. In addition, THOC4 specifically binds to rhesus (RH) promoter in erythroid, and might be a novel transcription cofactor for erythroid-specific genes. SKAR shows high sequence homology with THOC4 and possesses one RRM as well. SKAR is widely expressed and localizes to the nucleus. It may be a critical player in the function of S6K1 in cell and organism growth control by binding the activated, hyperphosphorylated form of S6K1 but not S6K2. Furthermore, SKAR functions as a protein partner of the p50 subunit of DNA polymerase delta. In addition, SKAR may have particular importance in pancreatic beta cell size determination and insulin secretion.

eighth type I K homology (KH) RNA-binding domain found in vigilin and similar proteins; Vigilin, also called high density lipoprotein-binding protein, or HDL-binding protein, is a ubiquitous and highly conserved RNA-binding protein that shuttles between nucleus and cytoplasm presumably in contact with RNA molecules. It may be involved in chromosome partitioning at mitosis, facilitating translation and tRNA transport, and control of mRNA metabolism, including estrogen-mediated stabilization of vitellogenin mRNA. Vigilin is up-regulated by cholesterol loading of cells and functions to protect cells from over-accumulation of cholesterol. It may play a role in cell sterol metabolism. Disruption of human vigilin impairs chromosome condensation and segregation. Vigilin has a unique structure of 14-15 consecutively arranged, but non-identical K-homology (KH) domains which apparently mediate RNA-protein binding. The model corresponds to the eighth one.

RNA recognition motif 2 (RRM2) found in CUGBP Elav-like family member CELF-3, CELF-4, CELF-5, CELF-6 and similar proteins; This subgroup corresponds to the RRM2 of CELF-3, CELF-4, CELF-5, and CELF-6, all of which belong to the CUGBP1 and ETR-3-like factors (CELF) or BRUNOL (Bruno-like) family of RNA-binding proteins that display dual nuclear and cytoplasmic localizations and have been implicated in the regulation of pre-mRNA splicing and in the control of mRNA translation and deadenylation. CELF-3, expressed in brain and testis only, is also known as bruno-like protein 1 (BRUNOL-1), or CAG repeat protein 4, or CUG-BP- and ETR-3-like factor 3, or embryonic lethal abnormal vision (ELAV)-type RNA-binding protein 1 (ETR-1), or expanded repeat domain protein CAG/CTG 4, or trinucleotide repeat-containing gene 4 protein (TNRC4). It plays an important role in the pathogenesis of tauopathies. CELF-3 contains three highly conserved RNA recognition motifs (RRMs), also known as RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains): two consecutive RRMs (RRM1 and RRM2) situated in the N-terminal region followed by a linker region and the third RRM (RRM3) close to the C-terminus of the protein. The effect of CELF-3 on tau splicing is mediated mainly by the RNA-binding activity of RRM2. The divergent linker region might mediate the interaction of CELF-3 with other proteins regulating its activity or involved in target recognition. CELF-4, being highly expressed throughout the brain and in glandular tissues, moderately expressed in heart, skeletal muscle, and liver, is also known as bruno-like protein 4 (BRUNOL-4), or CUG-BP- and ETR-3-like factor 4. Like CELF-3, CELF-4 also contain three highly conserved RRMs. The splicing activation or repression activity of CELF-4 on some specific substrates is mediated by its RRM1/RRM2. On the other hand, both RRM1 and RRM2 of CELF-4 can activate cardiac troponin T (cTNT) exon 5 inclusion. CELF-5, expressed in brain, is also known as bruno-like protein 5 (BRUNOL-5), or CUG-BP- and ETR-3-like factor 5. Although its biological role remains unclear, CELF-5 shares same domain architecture with CELF-3. CELF-6, being strongly expressed in kidney, brain, and testis, is also known as bruno-like protein 6 (BRUNOL-6), or CUG-BP- and ETR-3-like factor 6. It activates exon inclusion of a cardiac troponin T minigene in transient transfection assays in a muscle-specific splicing enhancer (MSE)-dependent manner and can activate inclusion via multiple copies of a single element, MSE2. CELF-6 also promotes skipping of exon 11 of insulin receptor, a known target of CELF activity that is expressed in kidney. In addition to three highly conserved RRMs, CELF-6 also possesses numerous potential phosphorylation sites, a potential nuclear localization signal (NLS) at the C terminus, and an alanine-rich region within the divergent linker region.

They are homologous of Caenorhabditis elegans MEX-3 protein, a translational regulator that specifies the posterior blastomere identity in the early embryo and contributes to the maintenance of the germline totipotency. Mex-3 proteins are RNA-binding phosphoproteins involved in post-transcriptional regulatory mechanisms. They are characterized by containing two K-homology (KH) RNA-binding domains and a C-terminal RING finger. They bind RNA through their KH domains and shuttle between the nucleus and the cytoplasm via the CRM1-dependent export pathway. The model corresponds to the second KH domain.

RNA recognition motif 2 (RRM2) found in the Hu proteins family; This subfamily corresponds to the RRM2 of Hu proteins family which represents a group of RNA-binding proteins involved in diverse biological processes. Since the Hu proteins share high homology with the Drosophila embryonic lethal abnormal vision (ELAV) protein, the Hu family is sometimes referred to as the ELAV family. Drosophila ELAV is exclusively expressed in neurons and is required for the correct differentiation and survival of neurons in flies. The neuronal members of the Hu family include Hu-antigen B (HuB or ELAV-2 or Hel-N1), Hu-antigen C (HuC or ELAV-3 or PLE21), and Hu-antigen D (HuD or ELAV-4), which play important roles in neuronal differentiation, plasticity and memory. HuB is also expressed in gonads. Hu-antigen R (HuR or ELAV-1 or HuA) is the ubiquitously expressed Hu family member. It has a variety of biological functions mostly related to the regulation of cellular response to DNA damage and other types of stress. Moreover, HuR has an anti-apoptotic function during early cell stress response. It binds to mRNAs and enhances the expression of several anti-apoptotic proteins, such as p21waf1, p53, and prothymosin alpha. HuR also has pro-apoptotic function by promoting apoptosis when cell death is unavoidable. Furthermore, HuR may be important in muscle differentiation, adipogenesis, suppression of inflammatory response and modulation of gene expression in response to chronic ethanol exposure and amino acid starvation. Hu proteins perform their cytoplasmic and nuclear molecular functions by coordinately regulating functionally related mRNAs. In the cytoplasm, Hu proteins recognize and bind to AU-rich RNA elements (AREs) in the 3' untranslated regions (UTRs) of certain target mRNAs, such as GAP-43, vascular epithelial growth factor (VEGF), the glucose transporter GLUT1, eotaxin and c-fos, and stabilize those ARE-containing mRNAs. They also bind and regulate the translation of some target mRNAs, such as neurofilament M, GLUT1, and p27. In the nucleus, Hu proteins function as regulators of polyadenylation and alternative splicing. Each Hu protein contains three RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains). RRM1 and RRM2 may cooperate in binding to an ARE. RRM3 may help to maintain the stability of the RNA-protein complex, and might also bind to poly(A) tails or be involved in protein-protein interactions.

RNA recognition motif (RRM) found in RNA-binding protein RBM8A, RBM8B nd similar proteins; This subfamily corresponds to the RRM of RBM8, also termed binder of OVCA1-1 (BOV-1), or RNA-binding protein Y14, which is one of the components of the exon-exon junction complex (EJC). It has two isoforms, RBM8A and RBM8B, both of which are identical except that RBM8B is 16 amino acids shorter at its N-terminus. RBM8, together with other EJC components (such as Magoh, Aly/REF, RNPS1, Srm160, and Upf3), plays critical roles in postsplicing processing, including nuclear export and cytoplasmic localization of the mRNA, and the nonsense-mediated mRNA decay (NMD) surveillance process. RBM8 binds to mRNA 20-24 nucleotides upstream of a spliced exon-exon junction. It is also involved in spliced mRNA nuclear export, and the process of nonsense-mediated decay of mRNAs with premature stop codons. RBM8 forms a specific heterodimer complex with the EJC protein Magoh which then associates with Aly/REF, RNPS1, DEK, and SRm160 on the spliced mRNA, and inhibits ATP turnover by eIF4AIII, thereby trapping the EJC core onto RNA. RBM8 contains an N-terminal putative bipartite nuclear localization signal, one RNA recognition motif (RRM), also termed RBD (RNA binding domain) or RNP (ribonucleoprotein domain), in the central region, and a C-terminal serine-arginine rich region (SR domain) and glycine-arginine rich region (RG domain).

MSSP-1 is a double- and single-stranded DNA binding protein that belongs to the c-myc single-strand binding proteins (MSSP) family. It specifically recognizes the sequence CT(A/T)(A/T)T, and stimulates DNA replication in the system using SV40 DNA. MSSP-1 is identical with Scr2, a human protein which complements the defect of cdc2 kinase in Schizosaccharomyces pombe. MSSP-1 has been implied in regulating DNA replication, transcription, apoptosis induction, and cell-cycle movement, via the interaction with c-MYC, the product of protooncogene c-myc. MSSP-1 contains two RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains), both of which are responsible for the specific DNA binding activity as well as induction of apoptosis.

It binds single strand DNA (ssDNA) and RNA in vitro. It exhibits RNA chaperone activity and regulates negatively resistance responses to abiotic stresses during seed germination (e.g. salt, dehydration, and low temperature) and seedling growth (e.g. salt). The family also includes Nicotiana sylvestris chloroplastic 33 kDa ribonucleoprotein (NsCP33) and Arabidopsis thaliana chloroplastic 31 kDa ribonucleoprotein (AtCP31A). NsCP33 may be involved in splicing and/or processing of chloroplast RNA's.

RNA recognition motif 3 (RRM3) found found in type I polyadenylate-binding proteins; This subfamily corresponds to the RRM3 of type I poly(A)-binding proteins (PABPs), highly conserved proteins that bind to the poly(A) tail present at the 3' ends of most eukaryotic mRNAs. They have been implicated in the regulation of poly(A) tail length during the polyadenylation reaction, translation initiation, mRNA stabilization by influencing the rate of deadenylation and inhibition of mRNA decapping. The family represents type I polyadenylate-binding proteins (PABPs), including polyadenylate-binding protein 1 (PABP-1 or PABPC1), polyadenylate-binding protein 3 (PABP-3 or PABPC3), polyadenylate-binding protein 4 (PABP-4 or APP-1 or iPABP), polyadenylate-binding protein 5 (PABP-5 or PABPC5), polyadenylate-binding protein 1-like (PABP-1-like or PABPC1L), polyadenylate-binding protein 1-like 2 (PABPC1L2 or RBM32), polyadenylate-binding protein 4-like (PABP-4-like or PABPC4L), yeast polyadenylate-binding protein, cytoplasmic and nuclear (PABP or ACBP-67), and similar proteins. PABP-1 is an ubiquitously expressed multifunctional protein that may play a role in 3' end formation of mRNA, translation initiation, mRNA stabilization, protection of poly(A) from nuclease activity, mRNA deadenylation, inhibition of mRNA decapping, and mRNP maturation. Although PABP-1 is thought to be a cytoplasmic protein, it is also found in the nucleus. PABP-1 may be involved in nucleocytoplasmic trafficking and utilization of mRNP particles. PABP-1 contains four copies of RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains), a less well conserved linker region, and a proline-rich C-terminal conserved domain (CTD). PABP-3 is a testis-specific poly(A)-binding protein specifically expressed in round spermatids. It is mainly found in mammalian and may play an important role in the testis-specific regulation of mRNA homeostasis. PABP-3 shows significant sequence similarity to PABP-1. However, it binds to poly(A) with a lower affinity than PABP-1. PABP-1 possesses an A-rich sequence in its 5'-UTR and allows binding of PABP and blockage of translation of its own mRNA. In contrast, PABP-3 lacks the A-rich sequence in its 5'-UTR. PABP-4 is an inducible poly(A)-binding protein (iPABP) that is primarily localized to the cytoplasm. It shows significant sequence similarity to PABP-1 as well. The RNA binding properties of PABP-1 and PABP-4 appear to be identical. PABP-5 is encoded by PABPC5 gene within the X-specific subinterval, and expressed in fetal brain and in a range of adult tissues in mammalian, such as ovary and testis. It may play an important role in germ cell development. Moreover, unlike other PABPs, PABP-5 contains only four RRMs, but lacks both the linker region and the CTD. PABP-1-like and PABP-1-like 2 are the orthologs of PABP-1. PABP-4-like is the ortholog of PABP-5. Their cellular functions remain unclear. The family also includes the yeast PABP, a conserved poly(A) binding protein containing poly(A) tails that can be attached to the 3'-ends of mRNAs. The yeast PABP and its homologs may play important roles in the initiation of translation and in mRNA decay. Like vertebrate PABP-1, the yeast PABP contains four RRMs, a linker region, and a proline-rich CTD as well. The first two RRMs are mainly responsible for specific binding to poly(A). The proline-rich region may be involved in protein-protein interactions.

first type I K homology (KH) RNA-binding domain found in Arabidopsis thaliana RNA-binding KH domain-containing protein PEPPER and similar proteins; The family includes a group of plant RNA-binding KH domain-containing proteins, such as PEPPER, flowering locus K homology domain protein (FLK), RNA-binding KH domain-containing protein RCF3 and KH domain-containing protein HEN4. PEPPER regulates vegetative and gynoecium development. It acts as a positive regulator of the central floral repressor FLOWERING LOCUS C. In concert with HUA2, PEPPER antagonizes FLK by positively regulating FLC probably at transcriptional and post-transcriptional levels, and thus acts as a negative regulator of flowering. FLK, also called flowering locus KH domain protein, regulates positively flowering by repressing FLC expression and post-transcriptional modification. PEPPER and FLK contain three K-homology (KH) RNA-binding domains. RCF3, also called protein ENHANCED STRESS RESPONSE 1 (ESR1), or protein HIGH OSMOTIC STRESS GENE EXPRESSION 5 (HOS5), or protein REGULATOR OF CBF GENE EXPRESSION 3, or protein SHINY 1 (SHI1), acts as negative regulator of osmotic stress-induced gene expression. It is involved in the regulation of thermotolerance responses under heat stress. It functions as an upstream regulator of heat stress transcription factor (HSF) genes. HEN4, also called protein HUA ENHANCER 4, plays a role in floral reproductive organ identity in the third whorl and floral determinacy specification by specifically promoting the processing of AGAMOUS (AG) pre-mRNA. It functions in association with HUA1 and HUA2. RCF3 and HEN4 contain five KH RNA-binding domains. The model corresponds to the KH1 domain of PEPPER and FLK, as well as KH1 and KH3 domains of RCF3 and HEN4.

third type I K homology (KH) RNA-binding domain found in a family of fragile X mental retardation protein (FMR1) and fragile X related (FXR) proteins; The FMR1/FXR family includes FMR1 (also known as FMRP) and its two homologues, fragile X related 1 (FXR1) and 2 (FXR2). They are involved in translational regulation, particularly in neuronal cells and play an important role in the regulation of glutamate-mediated neuronal activity and plasticity. Each of these three proteins can form heteromers with the others, and each can also form homomers. Lack of expression of FMR1 results in mental retardation and macroorchidism. FXR1 and FXR2 may play important roles in the function of FMR1 and in the pathogenesis of the Fragile X Mental Retardation Syndrome. Members of this family contain three K-homology (KH) RNA-binding domains. The model corresponds to the third one.

RNA recognition motif 1 (RRM1) found in vertebrate heterogeneous nuclear ribonucleoprotein M (hnRNP M); This subgroup corresponds to the RRM1 of hnRNP M, a pre-mRNA binding protein that may play an important role in the pre-mRNA processing. It also preferentially binds to poly(G) and poly(U) RNA homopolymers. Moreover, hnRNP M is able to interact with early spliceosomes, further influencing splicing patterns of specific pre-mRNAs. hnRNP M functions as the receptor of carcinoembryonic antigen (CEA) that contains the penta-peptide sequence PELPK signaling motif. In addition, hnRNP M and another splicing factor Nova-1 work together as dopamine D2 receptor (D2R) pre-mRNA-binding proteins. They regulate alternative splicing of D2R pre-mRNA in an antagonistic manner. hnRNP M contains three RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains), and an unusual hexapeptide-repeat region rich in methionine and arginine residues (MR repeat motif).

RNA recognition motif (RRM) found in splicing factor U2AF 35 kDa subunit B (U2AF35B); This subgroup corresponds to the RRM of U2AF35B, also termed zinc finger CCCH domain-containing protein 60 (C3H60), which is one of the small subunits of U2 small nuclear ribonucleoprotein (snRNP) auxiliary factor (U2AF). It has been implicated in the recruitment of U2 snRNP to pre-mRNAs and is a highly conserved heterodimer composed of large and small subunits. Members in this family are mainly found in plant. They show high sequence homology to vertebrates U2AF35 that directly binds to the 3' splice site of the conserved AG dinucleotide and performs multiple functions in the splicing process in a substrate-specific manner. U2AF35B contains two N-terminal zinc fingers, a central RNA recognition motif (RRM), also termed RBD (RNA binding domain) or RNP (ribonucleoprotein domain), and a C-terminal arginine/serine (SR)-rich domain. In contrast to U2AF35, U2AF35B has a plant-specific conserved C-terminal region containing SERE motif(s), which may have an important function specific to higher plants.

MSSP-2 is a double- and single-stranded DNA binding protein that belongs to the c-myc single-strand binding proteins (MSSP) family. It specifically recognizes the sequence T(C/A)TT, and stimulates DNA replication in the system using SV40 DNA. MSSP-2 is identical with Scr3, a human protein which complements the defect of cdc2 kinase in Schizosaccharomyces pombe. MSSP-2 has been implied in regulating DNA replication, transcription, apoptosis induction, and cell-cycle movement, via the interaction with C-MYC, the product of protooncogene c-myc. MSSP-2 contains two RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains), both of which are responsible for the specific DNA binding activity as well as induction of apoptosis.

first type I K homology (KH) RNA-binding domain found in poly(rC)-binding protein 1 (PCBP1) and similar proteins; The family includes PCBP1 (also called alpha-CP1, or heterogeneous nuclear ribonucleoprotein E1, or hnRNP E1, or nucleic acid-binding protein SUB2.3) and PCBP2 (also called alpha-CP2, or heterogeneous nuclear ribonucleoprotein E2, or hnRNP E2). They are single-stranded nucleic acid binding proteins that bind preferentially to oligo dC. They act as iron chaperones for ferritin. In case of infection by poliovirus, PCBP1 plays a role in initiation of viral RNA replication in concert with the viral protein 3CD. PCBP2 is a major cellular poly(rC)-binding protein. It also binds poly(rU). PCBP2 negatively regulates cellular antiviral responses mediated by MAVS signaling. It acts as an adapter between MAVS and the E3 ubiquitin ligase ITCH, therefore triggering MAVS ubiquitination and degradation. PCBP2 forms a metabolon with the heme oxygenase 1/cytochrome P450 reductase complex for heme catabolism and iron transfer. Both PCBP1 and PCBP2 contain three K-homology (KH) RNA-binding domains.

PUF60 is an essential splicing factor that functions as a poly-U RNA-binding protein required to reconstitute splicing in depleted nuclear extracts. Its function is enhanced through interaction with U2 auxiliary factor U2AF65. PUF60 also controls human c-myc gene expression by binding and inhibiting the transcription factor far upstream sequence element (FUSE)-binding-protein (FBP), an activator of c-myc promoters. PUF60 contains two central RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains), and a C-terminal U2AF (U2 auxiliary factor) homology motifs (UHM) that harbors another RRM and binds to tryptophan-containing linear peptide motifs (UHM ligand motifs, ULMs) in several nuclear proteins. Research indicates that PUF60 binds FUSE as a dimer, and only the first two RRM domains participate in the single-stranded DNA recognition.

RBM19, also termed RNA-binding domain-1 (RBD-1), is a nucleolar protein conserved in eukaryotes. It is involved in ribosome biogenesis by processing rRNA and is essential for preimplantation development. It has a unique domain organization containing 6 conserved RNA recognition motifs (RRMs), also termed RBDs (RNA binding domains) or RNPs (ribonucleoprotein domains). MRD1 is encoded by a novel yeast gene MRD1 (multiple RNA-binding domain). It is well-conserved in yeast and its homologs exist in all eukaryotes. MRD1 is present in the nucleolus and the nucleoplasm. It interacts with the 35 S precursor rRNA (pre-rRNA) and U3 small nucleolar RNAs (snoRNAs). It is essential for the initial processing at the A0-A2 cleavage sites in the 35 S pre-rRNA. MRD1 contains 5 conserved RRMs, which may play an important structural role in organizing specific rRNA processing events.

It is a highly conserved heterodimer composed of large and small subunits; this family includes the small subunit of U2AF (U2AF35 or U2AF1) and U2AF 35 kDa subunit B (U2AF35B or C3H60). U2AF35 directly binds to the 3' splice site of the conserved AG dinucleotide and performs multiple functions in the splicing process in a substrate-specific manner. It promotes U2 snRNP binding to the branch-point sequences of introns through association with the large subunit of U2AF (U2AF65 or U2AF2). Although the biological role of U2AF35B remains unclear, it shows high sequence homolgy to U2AF35, which contains two N-terminal zinc fingers, a central RNA recognition motif (RRM), also termed RBD (RNA binding domain) or RNP (ribonucleoprotein domain), and a C-terminal arginine/serine (SR) -rich segment interrupted by glycines.

tenth type I K homology (KH) RNA-binding domain found in vigilin and similar proteins; Vigilin, also called high density lipoprotein-binding protein, or HDL-binding protein, is a ubiquitous and highly conserved RNA-binding protein that shuttles between nucleus and cytoplasm presumably in contact with RNA molecules. It may be involved in chromosome partitioning at mitosis, facilitating translation and tRNA transport, and control of mRNA metabolism, including estrogen-mediated stabilization of vitellogenin mRNA. Vigilin is up-regulated by cholesterol loading of cells and functions to protect cells from over-accumulation of cholesterol. It may play a role in cell sterol metabolism. Disruption of human vigilin impairs chromosome condensation and segregation.

type I K homology (KH) RNA-binding domain found in mitochondrial polyribonucleotide nucleotidyltransferase 1 (PNPT1) and similar proteins; PNPT1, also called 3'-5' RNA exonuclease OLD35, or PNPase old-35, or polynucleotide phosphorylase 1, or PNPase 1, or polynucleotide phosphorylase-like protein, is an RNA-binding protein implicated in numerous RNA metabolic processes. It catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'-to-5' direction. It acts as a mitochondrial intermembrane factor with RNA-processing exoribonulease activity. PNPT1 is a component of the mitochondrial degradosome (mtEXO) complex, that degrades 3' overhang double-stranded RNA with a 3'-to-5' directionality in an ATP-dependent manner. It is involved in the degradation of non-coding mitochondrial transcripts (MT-ncRNA) and tRNA-like molecules and required for correct processing and polyadenylation of mitochondrial mRNAs. PNPT1 also plays a role as a cytoplasmic RNA import factor that mediates the translocation of small RNA components, like the 5S RNA, the RNA subunit of ribonuclease P and the mitochondrial RNA-processing (MRP) RNA, into the mitochondrial matrix.

second type I K homology (KH) RNA-binding domain found in vigilin and similar proteins; Vigilin, also called high density lipoprotein-binding protein, or HDL-binding protein, is a ubiquitous and highly conserved RNA-binding protein that shuttles between nucleus and cytoplasm presumably in contact with RNA molecules. It may be involved in chromosome partitioning at mitosis, facilitating translation and tRNA transport, and control of mRNA metabolism, including estrogen-mediated stabilization of vitellogenin mRNA. Vigilin is up-regulated by cholesterol loading of cells and functions to protect cells from over-accumulation of cholesterol. It may play a role in cell sterol metabolism. Disruption of human vigilin impairs chromosome condensation and segregation. Vigilin has a unique structure of 14-15 consecutively arranged, but non-identical K-homology (KH) domains which apparently mediate RNA-protein binding. The model corresponds to the second one.

type II K-homology (KH) RNA-binding domain superfamily; The K-homology (KH) domain binds single-stranded RNA or DNA, and is found in a wide variety of proteins including ribosomal proteins, transcription factors, and post-transcriptional modifiers of mRNA. There are two different KH domains that belong to different protein folds, but share a single "minimal KH motif" which is folded into a beta-alpha-alpha-beta unit. In addition to the core, type II KH domains (e.g. ribosomal protein S3) include an N-terminal extension while type I KH domains (e.g. hnRNP K) contain a C-terminal extension, connected to the KH motif by variable loops that are different in different KH domains, whether they are type I or type II. KH-II superfamily members contain one or two KH domains, most of which are canonical type II KH domains that have the signature motif GXXG (where X represents any amino acid). The first KH domain found in archaeal cleavage and polyadenylation specificity factors (CPSFs) is a non-canonical type II KH domain that lacks the GXXG motif. Some others have mutated GXXG motifs which may or may not have nucleic acid binding ability.
