PRY/SPRY domain in tripartite motif-containing proteins, TRIM9 and TRIM67; This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of TRIM9 proteins. TRIM9 protein is expressed mainly in the cerebral cortex, and functions as an E3 ubiquitin ligase. It has been shown that TRIM9 is localized to the neurons in the normal human brain and its immunoreactivity in affected brain areas in Parkinson's disease and dementia with Lewy bodies is severely decreased, possibly playing an important role in the regulation of neuronal function and participating in pathological process of Lewy body disease through its ligase. TRIM67 negatively regulates Ras activity via degradation of 80K-H, leading to neural differentiation, including neuritogenesis.

B-box-type 2 zinc finger found in tripartite motif-containing protein 9 (TRIM9) and similar proteins; TRIM9 (the human ortholog of rat Spring), also termed RING finger protein 91 (RNF91), is a brain-specific E3 ubiquitin-protein ligase collaborating with an E2 ubiquitin conjugating enzyme UBCH5b. TRIM9 plays an important role in the regulation of neuronal functions and participates in the neurodegenerative disorders through its ligase activity. It interacts with the WD repeat region of beta-transducer repeat-containing protein (beta-TCP) through its N-terminal degron motif (DSGXXS) depending on the phosphorylation status, and thus negatively regulate nuclear factor-kappaB (NF-kappaB) activation in the NF-kappaB pro-inflammatory signaling pathway. Moreover, TRIM9 acts as a critical catalytic link between Netrin-1 and exocytosis soluble NSF attachment receptor protein (SNARE) machinery in murine cortical neurons. It promotes SNARE-mediated vesicle fusion and axon branching in a Netrin-dependent manner. TRIM9 belongs to the C-I subclass of TRIM (tripartite motif) family of proteins that are defined by their N-terminal RBCC (RING, Bbox, and coiled coil) domains, including three consecutive zinc-binding domains, a RING finger, Bbox1 and Bbox2, and a coiled coil region, as well as a COS (carboxyl-terminal subgroup one signature) box, the fibronectin type III domain and the SPRY/B30.2 domain positioned C-terminal to the RBCC domain. The type 2 B-box (Bbox2) zinc finger is characterized by a CHC3H2 zinc-binding consensus motif.

SPRY domain in the suppressor of cytokine signaling 3 (SOCS3) family; The SPRY domain-containing SOCS box protein family (SPSB1-4, also known as SSB-1 to -4) is composed of a central SPRY protein interaction domain and a C-terminal SOCS box. All four SPSB proteins interact with c-Met, the hepatocyte growth factor receptor, but SOCS3 regulates cellular response to a variety of cytokines such as leukemia inhibitory factor (LIF) and interleukin 6. SOCS3, along with SOCS1, are expressed by immune cells and cells of the central nervous system (CNS) and have the potential to impact immune processes within the CNS. In non-small cell lung cancer (NSCLC), SOCS3 is silenced and proline-rich tyrosine kinase 2 (Pyk2) is over-expressed; it has been suggested that SOCS3 could be an effective way to prevent the progression of NSCLC due to its role in regulating Pyk2 expression.

SPRY domain; SPRY domains, first identified in the SP1A kinase of Dictyostelium and rabbit Ryanodine receptor (hence the name), are homologous to B30.2. SPRY domains have been identified in at least 11 protein families, covering a wide range of functions, including regulation of cytokine signaling (SOCS), RNA metabolism (DDX1 and hnRNP), immunity to retroviruses (TRIM5alpha), intracellular calcium release (ryanodine receptors or RyR) and regulatory and developmental processes (HERC1 and Ash2L). B30.2 also contains residues in the N-terminus that form a distinct PRY domain structure; i.e. B30.2 domain consists of PRY and SPRY subdomains. B30.2 domains comprise the C-terminus of three protein families: BTNs (receptor glycoproteins of immunoglobulin superfamily); several TRIM proteins (composed of RING/B-box/coiled-coil or RBCC core); Stonutoxin (secreted poisonous protein of the stonefish Synanceia horrida). TRIM/RBCC proteins are involved in a variety of processes, including apoptosis, cell cycle regulation, cell growth, senescence, viral response, meiosis, cell differentiation, and vesicular transport. Genes belonging to this family are implicated in several human diseases that vary from cancer to rare genetic syndromes. The PRY-SPRY domain in these TRIM families is suggested to serve as the target binding site. While SPRY domains are evolutionarily ancient, B30.2 domains are a more recent adaptation where the SPRY/PRY combination is a possible component of immune defense. Mutations found in the SPRY-containing proteins have shown to cause Mediterranean fever and Opitz syndrome.

SPRY domain in Ash2; This SPRY domain is found at the C-terminus of Ash2 (absent, small, or homeotic discs 2) -like proteins, core components of all mixed-lineage leukemia (MLL) family histone methyltransferases. Ash2 is a member of the trithorax group of transcriptional regulators of the Hox genes. Recent studies show that the SPRY domain of Ash2 mediates the interaction with RbBP5 and has an important role in regulating the methyltransferase activity of MLL complexes. In yeast, Ash2 is involved in histone methylation and is required for the earliest stages of embryogenesis.

RING finger, HC subclass, found in tripartite motif-containing protein 46 (TRIM46) and similar proteins; TRIM46, also known as gene Y protein (GeneY) or tripartite, fibronectin type-III and C-terminal SPRY motif protein (TRIFIC), is a microtubule-associated protein that specifically localizes to the proximal axon, partly overlaps with the axon initial segment (AIS) at later stages, and organizes uniform microtubule orientation in axons. It controls neuronal polarity and axon specification by driving the formation of parallel microtubule arrays. TRIM46 belongs to the C-I subclass of the TRIM (tripartite motif) family of proteins, which are defined by their N-terminal RBCC (RING, Bbox, and coiled coil) domains, including three consecutive zinc-binding domains, a C3HC4-type RING-HC finger, Bbox2, and a coiled coil region, as well as a COS (carboxyl-terminal subgroup one signature) box, a fibronectin type III (FN3) domain, a PRY domain and a B30.2/SPRY (SplA and ryanodine receptor) domain positioned C-terminal to the RBCC domain.

RING finger, HC subclass, found in tripartite motif-containing protein TRIM65 and similar proteins; TRIM65 is an E3 ubiquitin-protein ligase that interacts with the innate immune receptor MDA5, enhancing its ability to stimulate interferon-beta signaling. It functions as a potential oncogenic protein that negatively regulates p53 through ubiquitination, providing insight into the development of novel approaches targeting TRIM65 for non-small cell lung carcinoma (NSCLC) treatment, and also overcoming chemotherapy resistance. Moreover, TRIM65 negatively regulates microRNA-driven suppression of mRNA translation by targeting TNRC6 proteins for ubiquitination and degradation. TRIM65 belongs to the C-IV subclass of the TRIM (tripartite motif) family of proteins that are defined by their N-terminal RBCC (RING, Bbox, and coiled coil) domains, including three consecutive zinc-binding domains, a C3HC4-type RING-HC finger, Bbox1 and Bbox2, and a coiled coil region, as well as a B30.2/SPRY (SplA and ryanodine receptor) domain positioned C-terminal to the RBCC domain.

PRY/SPRY domain in tripartite motif-containing (TRIM) proteins, including TRIM14-like, TRIM16-like, TRIM25-like, TRIM47-like, TRIM65 and RNF135, and stonustoxin; This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of several Class I TRIM proteins, including TRIM14, TRIM16 and TRIM25, TRIM47 as well as RING finger protein RNF135 and stonustoxin, a secreted poisonous protein of the stonefish Synanceja horrida. TRIM16 (also known as estrogen-responsive B box protein or EBBP) has E3 ubiquitin ligase activity. It is a regulator of keratinocyte differentiation and a tumor suppressor in retinoid-sensitive neuroblastoma. TRIM25 (also called Efp) ubiquitinates the N terminus of the viral RNA receptor retinoic acid-inducible gene-I (RIG-I) in response to viral infection, leading to activation of the RIG-I signaling pathway, thus resulting in type I interferon production to limit viral replication. It has been shown that the influenza A virus targets TRIM25 and disables its antiviral function. TRIM47, also known as GOA (Gene overexpressed in astrocytoma protein) or RNF100 (RING finger protein 100), is highly expressed in kidney tubular cells, but low expressed in most tissue. It is overexpressed in astrocytoma tumor cells and plays an important role in the process of dedifferentiation that is associated with astrocytoma tumorigenesis. RNF135 ubiquitinates RIG-I (retinoic acid-inducible gene-I) to promote interferon-beta induction during the early phase of viral infection. Stonustoxin (STNX) is a hypotensive and lethal protein factor that also possesses other biological activities such as species-specific hemolysis (due to its ability to form pores in the cell membrane) and platelet aggregation, edema-induction, and endothelium-dependent vasorelaxation (mediated by the nitric oxide pathway and activation of potassium channels). The PRY-SPRY domain in these TRIM families is suggested to serve as the target binding site.

RING finger, HC subclass, found in tripartite motif-containing protein 59 (TRIM59) and similar proteins; TRIM59, also known as RING finger protein 104 (RNF104) or tumor suppressor TSBF-1, is a putative E3 ubiquitin-protein ligase that functions as a novel multiple cancer biomarker for immunohistochemical detection of early tumorigenesis. It is upregulated in gastric cancer and promotes gastric carcinogenesis by interacting with and targeting the P53 tumor suppressor for its ubiquitination and degradation. It also acts as a novel accessory molecule involved in cytotoxicity of BCG-activated macrophages (BAM). Moreover, TRIM59 may serve as a multifunctional regulator for innate immune signaling pathways.

B-box-type 1 zinc finger found in midline-1 (MID1) and similar proteins; MID1, also termed midin, or midline 1 RING finger protein, or putative transcription factor XPRF, or RING finger protein 59 (RNF59), or tripartite motif-containing protein 18 (TRI18), is a microtubule-associated E3 ubiquitin-protein ligase implicated in epithelial-mesenchymal differentiation, cell migration and adhesion, and programmed cell death along specific regions of the ventral midline during embryogenesis. It monoubiquinates the alpha4 subunit of protein phosphatase 2A (PP2A), promoting proteosomal degradation of the catalytic subunit of PP2A (PP2Ac) and preventing the A and B subunits from forming an active complex. It promotes allergen and rhinovirus-induced asthma through the inhibition of PP2A activity. It is strongly upregulated in cytotoxic lymphocytes (CTLs) and directs lytic granule exocytosis and cytotoxicity of killer T cells. Loss-of-function mutations in MID1 lead to the human X-linked Opitz G/BBB (XLOS) syndrome characterized by defective midline development during embryogenesis. MID1 belongs to the C-I subclass of TRIM (tripartite motif) family of proteins that are defined by their N-terminal RBCC (RING, Bbox, and coiled coil) domains, including three consecutive zinc-binding domains, a RING finger, Bbox1 and Bbox2, and a coiled coil region, as well as a COS (carboxyl-terminal subgroup one signature) box, the fibronectin type III domain and the SPRY/B30.2 domain positioned C-terminal to the RBCC domain. The type 1 B-box (Bbox1) zinc finger is characterized by a C6H2 zinc-binding consensus motif. MID1 heterodimerizes in vitro with its paralog MID2.

RING finger, HC subclass, found in tripartite motif-containing protein TRIM25 and similar proteins; TRIM25, also known as estrogen-responsive finger protein (EFP), RING finger protein 147 (RNF147), or RING-type E3 ubiquitin transferase, is an E3 ubiquitin/ISG15 ligase that is induced by estrogen and is therefore particularly abundant in placenta and uterus. TRIM25 regulates various cellular processes through E3 ubiquitin ligase activity, transferring ubiquitin and ISG15 to target proteins. It mediates K63-linked polyubiquitination of retinoic acid inducible gene I (RIG-I) that is crucial for downstream antiviral interferon signaling. It is also required for melanoma differentiation-associated gene 5 (MDA5) and mitochondrial antiviral signaling (MAVS, also known as IPS-1, VISA, Cardiff) mediated activation of nuclear factor-kappaB (NF-kappaB) and interferon production. Upon UV irradiation, TRIM25 interacts with mono-ubiquitinated PCNA and promotes its ISG15 modification (ISGylation), suggesting a crucial role in termination of error-prone translesion DNA synthesis. TRIM25 also functions as a novel regulator of p53 and Mdm2. It enhances p53 and Mdm2 abundance by inhibiting their ubiquitination and degradation in 26S proteasomes. Meanwhile, it inhibits p53's transcriptional activity and dampens the response to DNA damage, and is essential for medaka development and this dependence is rescued by silencing of p53. Moreover, TRIM25 is involved in the host cellular innate immune response against retroviral infection. It interferes with the late stage of feline leukemia virus (FeLV) replication. Furthermore, TRIM25 acts as an oncogene in gastric cancer. Its blockade by RNA interference inhibits migration and invasion of gastric cancer cells through transforming growth factor-beta (TGF-beta) signaling, suggesting it presents a novel target for the detection and treatment of gastric cancer. In addition, TRIM25 acts as an RNA-specific activator for Lin28a/TuT4-mediated uridylation. TRIM25 belongs to the C-IV subclass of TRIM (tripartite motif) family of proteins that are defined by their N-terminal RBCC (RING, Bbox, and coiled coil) domains, including three consecutive zinc-binding domains, a C3HC4-type RING-HC finger, Bbox1 and Bbox2, and a coiled coil region, as well as a B30.2/SPRY (SplA and ryanodine receptor) domain positioned C-terminal to the RBCC domain.

RING finger, HC subclass, found in tripartite motif-containing protein 36 (TRIM36) and similar proteins; TRIM36, the human ortholog of mouse Haprin, also known as RING finger protein 98 (RNF98) or zinc-binding protein Rbcc728, is an E3 ubiquitin-protein ligase expressed in the germ plasm. It has been implicated in acrosome reaction, fertilization, and embryogenesis, as well as in carcinogenesis. TRIM36 functions upstream of Wnt/beta-catenin activation, and plays a role in controlling the stability of proteins regulating microtubule polymerization during cortical rotation, and subsequently dorsal axis formation. It is also potentially associated with chromosome segregation by interacting with the kinetochore protein centromere protein-H (CENP-H), and colocalizing with the microtubule protein alpha-tubulin. Its overexpression may cause chromosomal instability and carcinogenesis. It is, thus, a novel regulator affecting cell cycle progression. Moreover, TRIM36 plays a critical role in the arrangement of somites during embryogenesis. TRIM36 belongs to the C-I subclass of the TRIM (tripartite motif) family of proteins that are defined by their N-terminal RBCC (RING, Bbox, and coiled coil) domains, including three consecutive zinc-binding domains, a C3HC4-type RING-HC finger, Bbox2, and a coiled coil region, as well as a COS (carboxyl-terminal subgroup one signature) box, a fibronectin type III (FN3) domain, a PRY domain and a B30.2/SPRY (SplA and ryanodine receptor) domain positioned C-terminal to the RBCC domain.

B-box-type 2 zinc finger (Bbox2); The B-box-type zinc finger is a short zinc binding domain of around 40 amino acid residues in length. It has been found in transcription factors, ribonucleoproteins and proto-oncoproteins, such as in TRIM (tripartite motif) proteins that consist of an N-terminal RING finger (originally called an A-box), followed by 1-2 B-box domains and a coiled-coil domain (also called RBCC for Ring, B-box, Coiled-Coil). The B-box-type zinc finger often presents in combination with other motifs, like RING zinc finger, NHL motif, coiled-coil or RFP domain in functionally unrelated proteins, most likely mediating protein-protein interaction. Based on different consensus sequence and the spacing of the 7-8 zinc-binding residues, B-box-type zinc fingers can be divided into two groups, type 1 (Bbox1: C6H2) and type 2 (Bbox2: CHC3H2). The family corresponds to type 2 B-box (Bbox2).

RING finger, HC subclass, found in tripartite motif-containing proteins, TRIM7, TRIM11 and TRIM27, and similar proteins; TRIM7, TRIM11 and TRIM27, closely related tripartite motif-containing proteins, belong to the C-IV subclass of the TRIM (tripartite motif) family of proteins that are defined by their N-terminal RBCC (RING, Bbox, and coiled coil) domains, including three consecutive zinc-binding domains, a C3HC4-type RING-HC finger, Bbox2, and a coiled coil region, as well as a SPRY/B30.2 domain positioned C-terminal to the RBCC domain. TRIM7, also known as glycogenin-interacting protein (GNIP) or RING finger protein 90 (RNF90), is an E3 ubiquitin-protein ligase that mediates c-Jun/AP-1 activation by Ras signalling. Its phosphorylation and activation by MSK1 in response to direct activation by the Ras-Raf-MEK-ERK pathway can stimulate TRIM7 E3 ubiquitin ligase activity in mediating Lys63-linked ubiquitination of the AP-1 coactivator RACO-1, leading to RACO-1 protein stabilization. Moreover, TRIM7 binds and activates glycogenin, the self-glucosylating initiator of glycogen biosynthesis. TRIM11, also known as protein BIA1, or RING finger protein 92 (RNF92), is an E3 ubiquitin-protein ligase involved in the development of the central nervous system. It is overexpressed in high-grade gliomas and promotes proliferation, invasion, migration and glial tumor growth. TRIM11 acts as a potential therapeutic target for congenital central hypoventilation syndrome (CCHS) by mediating the degradation of CCHS-associated polyalanine-expanded Phox2b. TRIM11 modulates the function of neurogenic transcription factor Pax6 through the ubiquitin-proteosome system, and thus plays an essential role for Pax6-dependent neurogenesis. It also binds to and destabilizes a key component of the activator-mediated cofactor complex (ARC105), humanin, a neuroprotective peptide against Alzheimer's disease-relevant insults, and further regulates ARC105 function in transforming growth factor beta (TGFbeta) signaling. Moreover, TRIM11 negatively regulates retinoic acid-inducible gene-I (RIG-I)-mediated interferon-beta (IFNbeta) production and antiviral activity by targeting TANK-binding kinase-1 (TBK1). It may contribute to the endogenous restriction of retroviruses in cells. It enhances N-tropic murine leukemia virus (N-MLV) entry by interfering with Ref1 restriction. It also suppresses the early steps of human immunodeficiency virus HIV-1 transduction, resulting in decreased reverse transcripts. TRIM27, also known as RING finger protein 76 (RNF76), RET finger protein (RFP), or zinc finger protein RFP, is a nuclear E3 ubiquitin-protein ligase that is highly expressed in testis and in various tumor cell lines. Expression of TRIM27 is associated with prognosis of colon and endometrial cancers. TRIM27 was first identified as a fusion partner of the RET receptor tyrosine kinase. It functions as a transcriptional repressor and associates with several proteins involved in transcriptional activity, such as enhancer of polycomb 1 (Epc1), a member of the Polycomb group proteins, and Mi-2beta, a main component of the nucleosome remodeling and deacetylase (NuRD) complex, and the cell cycle regulator retinoblastoma protein (RB1). It also interacts with HDAC1, leading to downregulation of thioredoxin binding protein 2 (TBP-2), which inhibits the function of thioredoxin. Moreover, TRIM27 mediates Pax7-induced ubiquitination of MyoD in skeletal muscle atrophy. In addition, it inhibits muscle differentiation by modulating serum response factor (SRF) and Epc1. TRIM27 promotes a non-canonical polyubiquitination of PTEN, a lipid phosphatase that catalyzes PtdIns(3,4,5)P3 (PIP3) to PtdIns(4,5)P2 (PIP2). It is an IKKepsilon-interacting protein that regulates IkappaB kinase (IKK) function and negatively regulates signaling involved in the antiviral response and inflammation. TRIM27 also forms a protein complex with MBD4 or MBD2 or MBD3, and thus plays an important role in the enhancement of transcriptional repression through MBD proteins in tumorigenesis, spermatogenesis, and embryogenesis. It is a component of an estrogen receptor 1 (ESR1) regulatory complex that is involved in estrogen receptor-mediated transcription in MCF-7 cells.

PRY/SPRY domain, also known as B30.2; This domain contains residues in the N-terminus that form a distinct PRY domain structure such that the B30.2 domain consists of PRY and SPRY subdomains. B30.2 domains comprise the C-terminus of three protein families: BTNs (receptor glycoproteins of immunoglobulin superfamily); several TRIM proteins (composed of RING/B-box/coiled-coil core); Stonutoxin (secreted poisonous protein of the stonefish Synanceia horrida). While SPRY domains are evolutionarily ancient, B30.2 domains are a more recent adaptation where the SPRY/PRY combination is a possible component of immune defense. Among the TRIM proteins, also known as the N-terminal RING finger/B-box/coiled coil (RBCC) family, only Classes I and II contain the B30.2 domain that has evolved under positive selection. Class I TRIM proteins include multiple members involved in antiviral immunity at various levels of interferon signaling cascade. Among the 75 human TRIMs, roughly half enhance immune response, which they do at multiple levels in signaling pathways. The PRY-SPRY domain in these TRIM families is suggested to serve as the target binding site.

B-box-type 2 zinc finger found in tripartite motif-containing protein 36 (TRIM36) and similar proteins; TRIM36, human ortholog of mouse Haprin, also known as RING finger protein 98 (RNF98) or zinc-binding protein Rbcc728, is an E3 ubiquitin-protein ligase expressed in the germ plasm. It has been implicated in acrosome reaction, fertilization, and embryogenesis, as well as in carcinogenesis. TRIM36 functions upstream of Wnt/beta-catenin activation, and plays a role in controlling the stability of proteins regulating microtubule polymerization during cortical rotation, and subsequently dorsal axis formation. It is also potentially associated with chromosome segregation through interacting with the kinetochore protein centromere protein-H (CENP-H), and colocalizing with the microtubule protein alpha-tubulin. Its overexpression may cause chromosomal instability and carcinogenesis. It is, thus, a novel regulator affecting cell cycle progression. Moreover, TRIM36 plays a critical role in the arrangement of somites during embryogenesis. TRIM36 belongs to the C-I subclass of TRIM (tripartite motif) family of proteins that are defined by their N-terminal RBCC (RING, Bbox, and coiled coil) domains, including three consecutive zinc-binding domains, a RING finger, Bbox1 and Bbox2, and a coiled coil region, as well as a COS (carboxyl-terminal subgroup one signature) box, a fibronectin type III (FN3) domain, and a B30.2/SPRY (SplA and ryanodine receptor) domain positioned C-terminal to the RBCC domain. The type 2 B-box (Bbox2) zinc finger is characterized by a CHC3H2 zinc-binding consensus motif.

B-box-type 1 zinc finger found in tripartite motif-containing proteins, TRIM36, TRIM46 and similar proteins; The family includes tripartite motif-containing proteins, TRIM36 and TRIM46, both of which belong to the C-I subclass of TRIM (tripartite motif) family of proteins that are defined by their N-terminal RBCC (RING, Bbox, and coiled coil) domains, including three consecutive zinc-binding domains, a RING finger, Bbox1 and Bbox2, and a coiled coil region, as well as a COS (carboxyl-terminal subgroup one signature) box, a fibronectin type III (FN3) domain, and a B30.2/SPRY (SplA and ryanodine receptor) domain positioned C-terminal to the RBCC domain. The type 1 B-box (Bbox1) zinc finger is characterized by a C6H2 zinc-binding consensus motif. TRIM36, the human ortholog of mouse Haprin, also known as RING finger protein 98 (RNF98) or zinc-binding protein Rbcc728, is an E3 ubiquitin-protein ligase expressed in the germ plasm.

Moreover, TRIM36 plays a critical role in the arrangement of somites during embryogenesis. TRIM46, also known as gene Y protein (GeneY) or tripartite, fibronectin type-III and C-terminal SPRY motif protein (TRIFIC), is a microtubule-associated protein that specifically localizes to the proximal axon, partly overlaps with the axon initial segment (AIS) at later stages, and organizes uniform microtubule orientation in axons. It controls neuronal polarity and axon specification by driving the formation of parallel microtubule arrays.

PRY/SPRY domain in tripartite motif-binding protein 7 (TRIM7)-like, including TRIM7, TRIM10, TRIM15, TRIM26, TRIM39, TRIM41; This domain, consisting of the distinct N-terminal PRY subdomain followed by the SPRY subdomain, is found at the C-terminus of several tripartite motif-containing (TRIM) proteins, including TRIM7 (also referred to as glycogenin-interacting protein, RING finger protein 90 or RNF90), TRIM10, TRIM15, TRIM26, TRIM39 and TRIM41. TRIM7 or GNIP interacts with glycogenin and stimulates its self-glucosylating activity via its SPRY domain. TRIM10 (also known as hematopoietic RING finger 1 (HERF1) or TRIM10/HERF1) plays a key role in definitive erythroid development; downregulation of the Spi-1/PU.1 oncogene induces the expression of TRIM10/HERF1, a key factor required for terminal erythroid cell differentiation and survival. Antiviral activity of TRIM15 is dependent on the ability of its B-box to interact with the MLV Gag precursor protein; downregulation of TRIM15, along with TRIM11, enhances virus release suggesting that these proteins contribute to the endogenous restriction of retroviruses in cells. Tripartite motif-containing 26 (TRIM26) function is as yet unknown; however, since it is localized in the human histocompatibility complex (MHC) class I region, TRIM26 may play a role in immune response although studies show no association between TRIM26 polymorphisms and the risk of aspirin-exacerbated respiratory disease. TRIM39 is a MOAP-1 (Modulator of Apoptosis)-binding protein that stabilizes MOAP-1 through inhibition of its poly-ubiquitination process. TRIM41 (also known as RING finger-interacting protein with C kinase or RINCK) functions as an E3 ligase that catalyzes the ubiquitin-mediated degradation of protein kinase C.

Mutations in the human MID1 gene result in X-linked Opitz G/BBB syndrome (OS), a disorder affecting development of midline structures, causing craniofacial, urogenital, gastrointestinal and cardiovascular abnormalities. A unique MID1 gene mutation located in a variable loop in the SPRY domain alters conformation of the binding pocket and may affect the binding affinity to the PRY/SPRY domain.

RING finger, HC subclass, found in muscle-specific RING finger protein 2 (MuRF-2) and similar proteins; MuRF-2, also known as tripartite motif-containing protein 55 (TRIM55) or RING finger protein 29 (RNF29), is a muscle-specific E3 ubiquitin-protein ligase in ubiquitin-mediated muscle protein turnover and is also a ligand of the transactivation domain of the serum response transcription factor (SRF). It is predominantly slow-fibre associated and highly expressed in embryonic skeletal muscle. MuRF-2 associates transiently with microtubules, myosin, and titin during sarcomere assembly. It has been implicated in microtubule, intermediate filament, and sarcomeric M-line maintenance in striated muscle development, as well as in signaling from the sarcomere to the nucleus. It plays an important role in the earliest stages of skeletal muscle differentiation and myofibrillogenesis. It is developmentally downregulated and is assembled at the M-line region of the sarcomere and with microtubules. MuRF-2 belongs to the C-II subclass of the TRIM (tripartite motif) family of proteins that are defined by their N-terminal RBCC (RING, Bbox, and coiled coil) domains, including three consecutive zinc-binding domains, a C3HC4-type RING-HC finger, Bbox2, and a coiled coil region, as well as a COS (carboxyl-terminal subgroup one signature) box, and an acidic residue-rich (AR) domain. It also harbors a MURF family-specific conserved box (MFC) between its RING-HC finger and Bbox domains.

RING finger, HC subclass, found in midline-1 (MID1), midline-2 (MID2) and similar proteins; MID1, also known as midin, midline 1 RING finger protein, putative transcription factor XPRF, RING finger protein 59 (RNF59), or tripartite motif-containing protein 18 (TRIM18), is a microtubule-associated E3 ubiquitin-protein ligase implicated in epithelial-mesenchymal differentiation, cell migration and adhesion, and programmed cell death along specific regions of the ventral midline during embryogenesis. MID2, also known as midin-2, midline defect 2, RING finger protein 60 (RNF60), or tripartite motif-containing protein 1 (TRIM1), associates with the microtubule network and may at least partially compensate for the loss of MID1. Both MID1 and MID2 interacts with Alpha 4, which is a regulatory subunit of PP2-type phosphatases, such as PP2A, and an integral component of the rapamycin-sensitive signaling pathway. They also play a central role in the regulation of granule exocytosis. Functional redundancy exists between MID1 and MID2 in cytotoxic lymphocytes (CTL). Both MID1 and MID2 belong to the C-I subclass of the TRIM (tripartite motif) family of proteins that are defined by their N-terminal RBCC (RING, Bbox, and coiled coil) domains, including three consecutive zinc-binding domains, a C3HC4-type RING-HC finger, Bbox1 and Bbox2, and a coiled coil region, as well as a COS (carboxyl-terminal subgroup one signature) box, a fibronectin type III (FN3) domain, and a B30.2/SPRY (SplA and ryanodine receptor) domain positioned C-terminal to the RBCC domain.
