PHD finger found in PYGO proteins; The family includes Drosophila melanogaster protein pygopus (dPYGO) and its two homologs, PYGO1 and PYGO2. dPYGO is a fundamental Wnt signaling transcriptional component in Drosophila. PYGO1 is essential for the association with Legless (Lgs)/Bcl9 that acts an adaptor between Pygopus (Pygo) and Arm/beta-catenin. dPYGO and PYGO2 function as context-dependent beta-catenin coactivators, and they bind di- and trimethylated lysine 4 of histone H3 (H3K4me2/3). Moreover, PYGO2 acts as a histone methylation reader, and a chromatin remodeler in a testis-specific and Wnt-unrelated manner. It also mediates chromatin regulation and links Wnt signaling and Notch signaling to suppress the luminal/alveolar differentiation competence of mammary stem and basal cells. PYGO2 also plays a new role in rRNA transcription during cancer cell growth. It regulates mammary tumor initiation and heterogeneity in MMTV-Wnt1 mice. All family members contain a plant homeodomain (PHD) finger. : Pssm-ID: 277026 Cd Length: 54 Bit Score: 103.60 E-value: 4.17e-29

PHD zinc finger; The plant homeodomain (PHD) finger is a C4HC3 zinc-finger-like motif found in nuclear proteins thought to be involved in epigenetics and chromatin-mediated transcriptional regulation. The PHD finger binds two zinc ions using the so-called 'cross-brace' motif and is thus structurally related to the RING finger and the FYVE finger. It is not yet known if PHD fingers have a common molecular function. Several reports suggest that it can function as a protein-protein interacton domain and it was recently demonstrated that the PHD finger of p300 can cooperate with the adjacent BROMO domain in nucleosome binding in vitro. Other reports suggesting that the PHD finger is a ubiquitin ligase have been refuted as these domains were RING fingers misidentified as PHD fingers.

159-212 | 1.10e-06 | ||
PHD finger found in Transcription factor 19 (TCF-19), Lysine-specific demethylase KDM5A and KDM5B, and other similar proteins; TCF-19 was identified as a putative trans-activating factor with expression beginning at the late G1-S boundary in dividing cells. It functions as a novel islet factor necessary for proliferation and survival in the INS-1 beta cell line. It plays an important role in susceptibility to both Type 1 Diabetes Mellitus (T1DM) and Type 2 Diabetes Mellitus (T2DM); it has been suggested that it may positively impact beta cell mass under conditions of beta cell stress and increased insulin demand. KDM5A was originally identified as a retinoblastoma protein (Rb)-binding partner and its inactivation may be important for Rb to promote differentiation. It is involved in transcription through interaction with TBP, p107, nuclear receptors, Myc, Sin3/HDAC, Mad1, RBP-J, CLOCK, and BMAL1. KDM5B has a restricted expression pattern in the testis, ovary, and transiently in the mammary gland of the pregnant female and has been shown to be upregulated in breast cancer, prostate cancer, and lung cancer, suggesting a potential role in tumorigenesis. Both KDM5A and KDM5B function as trimethylated histone H3 lysine 4 (H3K4me3) demethylases. This family also includes Caenorhabditis elegans Lysine-specific demethylase 7 homolog (ceKDM7A). ceKDM7A (also termed JmjC domain-containing protein 1.2, PHD finger protein 8 homolog, or PHF8 homolog) is a plant homeodomain (PHD)- and JmjC domain-containing protein that functions as a histone demethylase specific for H3K9me2 and H3K27me2. The binding of the PHD finger to H3K4me3 guides H3K9me2- and H3K27me2-specific demethylation by its catalytic JmjC domain in a trans-histone regulation mechanism. In addition, this family includes plant protein OBERON 1 and OBERON 2, Alfin1-like (AL) proteins, histone acetyltransferases (HATs) HAC, and AT-rich interactive domain-containing protein 4 (ARID4).

PHD finger superfamily; The PHD finger superfamily includes a canonical plant homeodomain (PHD) finger typically characterized as Cys4HisCys3, and a non-canonical extended PHD finger, characterized as Cys2HisCys5HisCys2His. Variations include the RAG2 PHD finger characterized by Cys3His2Cys2His and the PHD finger 5 found in nuclear receptor-binding SET domain-containing proteins characterized by Cys4HisCys2His. The PHD finger is also termed LAP (leukemia-associated protein) motif or TTC (trithorax consensus) domain. Single or multiple copies of PHD fingers have been found in a variety of eukaryotic proteins involved in the control of gene transcription and chromatin dynamics. PHD fingers can recognize the unmodified and modified histone H3 tail, and some have been found to interact with non-histone proteins. They also function as epigenome readers controlling gene expression through molecular recruitment of multi-protein complexes of chromatin regulators and transcription factors. The PHD finger domain SF is structurally similar to the RING and FYVE_like superfamilies. Pssm-ID: 276966 [Multi-domain] Cd Length: 48 Bit Score: 43.84 E-value: 1.49e-06

PHD finger found in PHD finger protein 3 (PHF3), and death-inducer obliterator variants Dido1, Dido2, and Dido3; PHF3 is a human homolog of yeast protein bypass of Ess1 (Bye1), a nuclear protein with a domain resembling the central domain in the transcription elongation factor TFIIS. It is ubiquitously expressed in normal tissues including brain, but its expression is significantly reduced or lost in glioblastomas. PHF3 contains an N-terminal plant homeodomain (PHD) finger, a central RNA polymerase II (Pol II)-binding TFIIS-like domain (TLD) domain, and a C-terminal Spen paralogue and orthologue C-terminal (SPOC) domain. This family also includes Dido gene encoding three alternative splicing variants (Dido1, 2, and 3), which have been implicated in a number of cellular processes such as apoptosis and chromosomal segregation, particularly in the hematopoietic system. Dido1 is important for maintaining embryonic stem (ES) cells and directly regulates the expression of pluripotency factors. It is the shortest isoform that contains only a highly conserved PHD finger responsible for the binding of histone H3 with a higher affinity for trimethylated lysine4 (H3K4me3). Gene Dido1 is a Bone morphogenetic protein (BMP) target gene and promotes BMP-induced melanoma progression. It also triggers apoptosis after nuclear translocation and caspase upregulation. Dido3 is the largest isoform and is ubiquitously expressed in all human tissues. It is dispensable for ES cell self-renewal and pluripotency, but is involved in the maintenance of stem cell genomic stability and tumorigenesis. Dido3 contains a PHD finger, a transcription elongation factor S-II subunit M (TFSIIM) domain, a SPOC module, and a long C-terminal region (CT) of unknown homology.

PHD finger 3 found in lysine-specific demethylase 5B (KDM5B); KDM5B, also termed Cancer/testis antigen 31 (CT31), or Histone demethylase JARID1B, or Jumonji/ARID domain-containing protein 1B (JARID1B), or PLU-1, or retinoblastoma-binding protein 2 homolog 1 (RBP2-H1 or RBBP2H1A), is a member of the JARID subfamily within the JmjC proteins. It has a restricted expression pattern in the testis, ovary, and transiently in the mammary gland of the pregnant female and has been shown to be upregulated in breast cancer, prostate cancer, and lung cancer, suggesting a potential role in tumorigenesis. KDM5B acts as a histone demethylase that catalyzes the removal of trimethylation of lysine 4 on histone H3 (H3K4me3), induced by polychlorinated biphenyls (PCBs). It also mediates demethylation of H3K4me2 and H3K4me1. Moreover, KDM5B functions as a negative regulator of hematopoietic stem cell (HSC) self-renewal and progenitor cell activity. KDM5B has also been shown to interact with the DNA binding transcription factors BF-1 and PAX9, as well as TIEG1/KLF10 (transforming growth factor-beta inducible early gene-1/Kruppel-like transcription factor 10), and possibly function as a transcriptional corepressor. KDM5B contains the catalytic JmjC domain, JmjN, the BRIGHT domain, which is an AT-rich interacting domain (ARID), and a Cys5HisCys2 zinc finger, as well as three plant homeodomain (PHD) fingers. This model corresponds to the third PHD finger. Pssm-ID: 277157 Cd Length: 50 Bit Score: 36.85 E-value: 5.96e-04

PHD finger 2 and 3 found in bromodomain and PHD finger-containing transcription factor (BPTF); BPTF, also termed nucleosome-remodeling factor subunit BPTF, or fetal Alz-50 clone 1 protein (FAC1), or fetal Alzheimer antigen, functions as a transcriptional regulator that exhibits altered expression and subcellular localization during neuronal development and neurodegenerative diseases such as Alzheimer's disease. It interacts with the human orthologue of the Kelch-like Ech-associated protein (Keap1). Its function and subcellular localization can be regulated by Keap1. Moreover, BPTF is a novel DNA-binding protein that recognizes the DNA sequence CACAACAC and represses transcription through this site in a phosphorylation-dependent manner. Furthermore, BPTF interacts with the Myc-associated zinc finger protein (ZF87/MAZ) and alters its transcriptional activity, which has been implicated in gene regulation in neurodegeneration. Some family members contain two or three plant homeodomain (PHD) fingers, which may be involved in complex formation with histone H3 trimethylated at K4 (H3K4me3). This family corresponds to the second and third PHD fingers. Pssm-ID: 277035 Cd Length: 47 Bit Score: 35.40 E-value: 1.63e-03
