PHD finger found in transcription initiation factor TFIID subunit 3 (TAF3); TAF3 (also termed 140 kDa TATA box-binding protein-associated factor, TBP-associated factor 3, transcription initiation factor TFIID 140 kDa subunit (TAF140), or TAFII-140, is an integral component of TFIID) is a general initiation factor (GTF) that plays a key role in preinitiation complex (PIC) assembly through core promoter recognition. The interaction of H3K4me3 with TAF3 directs global TFIID recruitment to active genes, which regulates gene-selective functions of p53 in response to genotoxic stress. TAF3 is highly enriched in embryonic stem cells and is required for endoderm lineage differentiation and prevents premature specification of neuroectoderm and mesoderm. Moreover, TAF3, along with TRF3, forms a complex that is essential for myogenic differentiation. TAF3 contains a plant homeodomain (PHD) finger. This family also includes Drosophila melanogaster BIP2 (Bric-a-brac interacting protein 2) protein, which functions as an interacting partner of D. melanogaster p53 (Dmp53).

PHD finger found in mixed lineage leukemia 5 (MLL5); MLL5 is a histone methyltransferase that plays a key role in hematopoiesis, spermatogenesis and cell cycle progression. It contains a single plant homeodomain (PHD) finger followed by a catalytic SET domain. MLL5 can be recruited to E2F1-responsive promoters to stimulate H3K4 trimethylation and transcriptional activation by binding to the cell cycle regulator host cell factor (HCF-1), thereby facilitating the cell cycle G1 to S phase transition. It is also involved in mitotic fidelity and genomic integrity by modulating the stability of the chromosomal passenger complex (CPC) via the interaction with Borealin. Moreover, MLL5 is a component of a complex associated with retinoic acid receptor that requires GlcN Acylation of its SET domain in order to activate its histone lysine methyltransferase activity. It also participates in the camptothecin (CPT)-induced p53 activation. Furthermore, MLL5 indirectly regulates H3K4 methylation, represses cyclin A2 (CycA) expression, and promotes myogenic differentiation.

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.

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).

Ecm5p is a JmjC domain-containing protein that directly removes histone lysine methylation via a hydroxylation reaction. It associates with the yeast Snt2p and Rpd3 deacetylase, which may play a role in regulating transcription in response to oxidative stress. Ecm5p promotes oxidative stress tolerance, while Snt2p ultimately decreases tolerance. Ecm5p contains an N-terminal ARID domain, a JmjC domain, and a C-terminal plant homeodomain (PHD) finger. Lid2p is a trimethyl H3K4 (H3K4me3) demethylase responsible for H3K4 hypomethylation in heterochromatin. It interacts with the histone lysine-9 methyltransferase, Clr4, through the Dos1/Clr8-Rik1 complex, and mediates H3K9 methylation and small RNA production. It also acts cooperatively with the histone modification enzymes Set1 and Lsd1 and plays an essential role in cross-talk between H3K4 and H3K9 methylation in euchromatin. Lid2p contains a JmjC domain, three PHD fingers and a JmjN domain. This model includes the second PHD finger of Lid2p.

The phosphorylation of PHF20 on Ser291 mediated by protein kinase B (PKB) is essential in tumorigenesis via the regulation of p53 mediated signaling. P20L1 is an active malignant brain tumor (MBT) domain-containing protein that binds to monomethylated lysine 142 on DNA (Cytosine-5) Methyltransferase 1 (DNMT1) (DNMT1K142me1) and colocalizes at the perinucleolar space in a SET7-dependent manner. Its MBT domain reads and controls enzyme levels of methylated DNMT1 in cells, thus representing a novel antagonist of DNMT1 proteasomal degradation. Both PHF20 and PHF20L1 contain an N-terminal MBT domain, two Tudor domains, a plant homeodomain (PHD) finger and the putative DNA-binding domains, AT hook and Cys2His2-type zinc finger.

PHD finger found in Schizosaccharomyces pombe meiosis-specific protein hop1 (Hop1p) and similar proteins; Fission yeast Hop1p, also termed linear element-associated protein hop1, is an S. pombe homolog of the synaptonemal complex (SC)-associated protein Hop1 in Saccharomyces cerevisiae. In contrast to S. cerevisiae, S. pombe forms thin threads, known as linear elements (LinEs), in meiotic nuclei, instead of a canonical synaptonemal complex. LinEs contain Rec10 protein and are evolutionary relics of SC axial elements. Fission yeast Hop1p is a linear element (LinE)-associated protein. It also associates with Rec10, which plays a role in recruiting the recombination machinery to chromatin. Hop1p contains an N-terminal HORMA (for Hop1p, Rev7p, and MAD2) domain and a C-terminal plant homeodomain (PHD) finger.

PHD finger found in Transcription factor 19 (TCF-19) and similar proteins; TCF-19, also termed transcription factor SC1, was identified as a putative trans-activating factor with expression beginning at the late G1-S boundary in dividing cells. It also 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. TCF-19 contains an N-terminal fork head association domain (FHA), a proline rich region, and a C-terminal plant homeodomain (PHD) finger. The FHA domain may serve as a nuclear signaling domain or as a phosphoprotein binding domain. The proline rich region is a common characteristic of trans-activating factors. The PHD finger may allow TCF-19 to interact with chromatin via methylated histone H3.

Both spAsh2p and D. melanogaster Ash2 contain a plant homeodomain (PHD) finger and a SPRY domain. In contrast, its counterpart in Saccharomyces cerevisiae, Bre2p, has no PHD finger and is not included in this family. spAsh2p shows histone H3 Lys4 (H3K4) methyltransferase activity through its PHD finger. It also interacts with Lid2p in S. pombe. Human Ash2L contains an atypical PHD finger that lacks part of the Cys4HisCys3 signature characteristic of PHD fingers, it binds to only one zinc ion through the second half of the motif and does not have histone tail binding activity.

PHD finger found in histone lysine demethylase PHF8; PHF8, also termed PHD finger protein 8, or KDM7B, is a monomethylated histone H4 lysine 20 (H4K20me1) demethylase that transcriptionally regulates many cell cycle genes. It also preferentially acts on H3K9me2 and H3K9me1. PHF8 is modulated by CDC20-containing anaphase-promoting complex (APC (cdc20)) and plays an important role in the G2/M transition. It acts as a critical molecular sensor for mediating retinoic acid (RA) treatment response in RAR alpha-fusion-induced leukemia. Moreover, PHF8 is essential for cytoskeleton dynamics and is associated with X-linked mental retardation. PHF8 contains an N-terminal plant homeodomain (PHD) finger followed by a JmjC domain. The PHD finger mediates binding to nucleosomes at active gene promoters and the JmjC domain catalyzes the demethylation of mono- or dimethyl-lysines.

PHD finger 2 found in polycomb repressive complex 2 (PRC2)-associated polycomb-like (PCL) family proteins MTF2, PHF19, and similar proteins; The PCL family includes PHD finger protein1 (PHF1) and its homologs metal-response element-binding transcription factor 2 (MTF2/PCL2) and PHF19/PCL3, which are accessory components of the Polycomb repressive complex 2 (PRC2) core complex and all contain an N-terminal Tudor domain followed by two plant homeodomain (PHD) fingers, and a C-terminal MTF2 domain. PCL proteins specifically recognize tri-methylated H3K36 (H3K36me3) through their N-terminal Tudor domains. The interaction between their Tudor domains and H3K36me3 is critical for both the targeting and spreading of PRC2 into active chromatin regions and for the maintenance of optimal repression of poised developmental genes where PCL proteins, H3K36me3, and H3K27me3 coexist. Moreover, unlike other PHD finger-containing proteins, the first PHD finger of PCL proteins do not display histone H3K4 binding affinity and they do not affect the Tudor domain binding to histones. This model corresponds to the second PHD finger.

PHD finger 1 found in metal-response element-binding transcription factor 2 (MTF2); MTF2, also termed metal regulatory transcription factor 2, or metal-response element DNA-binding protein M96, or polycomb-like protein 2 (PCL2), complexes with the polycomb repressive complex-2 (PRC2) in embryonic stem cells and regulates the transcriptional networks during embryonic stem cell self-renewal and differentiation. It recruits the PRC2 complex to the inactive X chromosome and target loci in embryonic stem cells. Moreover, MTF2 is required for PRC2-mediated Hox cluster repression. It activates the Cdkn2a gene and promotes cellular senescence, thus suppressing the catalytic activity of PRC2 locally. MTF2 consists of an N-terminal Tudor domain followed by two PHD fingers, and a C-terminal MTF2 domain. This model corresponds to the first PHD finger.

PHD finger 2 found in Histone-lysine N-methyltransferase 2D (KMT2D); KMT2D, also termed ALL1-related protein (ALR), is encoded by the gene that was named myeloid/lymphoid or mixed-lineage leukemia 4 (MLL4), a fourth human homolog of Drosophila trithorax, located on chromosome 12. KMT2D enzymatically generates trimethylated histone H3 Lys 4 (H3K4me3). It plays an essential role in differentiating the human pluripotent embryonal carcinoma cell line NTERA-2 clone D1 (NT2/D1) stem cells by activating differentiation-specific genes, such asHOXA1-3 and NESTIN. It is also a part of activating signal cointegrator-2 (ASC-2)-containing complex (ASCOM) that contains the transcriptional coactivator nuclear receptor coactivator 6 (NCOA6), KMT2C and KMT2D. The ASCOM complex is critical for nuclear receptor (NR) activation of bile acid transporter genes and is down regulated in cholestasis. KMT2D contains the catalytic domain SET, five plant homeodomain (PHD) fingers, two extended PHD (ePHD) fingers, Cys2HisCys5HisCys2His, a RING finger, an HMG (high-mobility group)-binding motif, and two FY-rich regions. This model corresponds to the second PHD finger.

PHD finger 1 found in autoimmune regulator (AIRE); AIRE, also termed autoimmune polyendocrinopathy candidiasis ectodermal dystrophy (APECED) protein, functions as a regulator of gene transcription in the thymus. It is essential for prevention of autoimmunity. AIRE plays a critical role in the induction of central tolerance. It promotes self-tolerance through tissue-specific antigen (TSA) expression. It also acts as an active regulator of chondrocyte differentiation. AIRE contains a homogeneously-staining region (HSR) or caspase-recruitment domain (CARD), a nuclear localization signal (NLS), a SAND (for Sp100, AIRE, nuclear phosphoprotein 41/75 or NucP41/75, and deformed epidermal auto regulatory factor 1 or Deaf1) domain, two plant homeodomain (PHD) fingers, and four LXXLL (where L stands for leucine) motifs. This model corresponds to the first PHD finger that recognizes the unmethylated tail of histone H3 and targets AIRE-dependent genes.

PHD finger found in ubiquitin-like PHD and RING finger domain-containing protein 2 (UHRF2); UHRF2 (also termed Np95/ICBP90-like RING finger protein (NIRF), Np95-like RING finger protein, nuclear protein 97, nuclear zinc finger protein Np97, RING finger protein 107, or E3 ubiquitin-protein ligase UHRF2) was originally identified as a ubiquitin ligase acting as a small ubiquitin-like modifier (SUMO) E3 ligase that enhances zinc finger protein 131 (ZNF131) SUMOylation but does not enhance ZNF131 ubiquitination. It also ubiquitinates PCNP, a PEST-containing nuclear protein. Moreover, UHRF2 functions as a nuclear protein involved in cell-cycle regulation and has been implicated in tumorigenesis. It interacts with cyclins, CDKs,p53, pRB, PCNA, HDAC1, DNMTs, G9a, methylated histone H3 lysine 9, and methylated DNA. It interacts with the cyclin E-CDK2 complex, ubiquitinates cyclins D1 and E1, induces G1 arrest, and is involved in the G1/S transition regulation. Furthermore, UHRF2 is a direct transcriptional target of the transcription factor E2F-1 in the induction of apoptosis. It recruits HDAC1 and binds to methyl-CpG. UHRF2 also participates in the maturation of Hepatitis B virus (HBV) by interacting with the HBV core protein and promoting its degradation. UHRF2 contains an N-terminal ubiquitin-like domain (UBL), a tandem Tudor domain (TTD), a plant homeodomain (PHD) finger, a SET- and RING-associated (SRA) domain, and a C-terminal RING finger.

PHD finger found in yeast orthologs of ING tumor suppressor family; The yeast orthologs of the plant homeodomain (PHD) finger-containing ING tumor suppressor family consists of chromatin modification-related protein YNG1 (Yng1p), YNG2 (Yng2p), and transcriptional regulatory protein PHO23 (Pho23p). Yng1p, also termed ING1 homolog 1, is one of the components of the NuA3 histone acetyltransferase (HAT) complex. Its PHD finger binding to H3 Trimethylated at K4 (H3K4me3) promotes NuA3 H3 HAT activity at K14 of H3 on chromatin. Yng2p, also termed ESA1-associated factor 4, or ING1 homolog 2, is a subunit of the NuA4 HAT complex. It plays a critical role in intra-S-phase DNA damage response. Pho23p is part of the Rpd3/Sin3 histone deacetylase (HDAC) complex. It is required for the normal function of Rpd3 in the silencing of rDNA, telomeric, and mating-type loci. Yng1p and Pho23p inhibit p53-dependent transcription. In contrast, Yng2p has the opposite effect. All family members contain an N-terminal ING histone-binding domain and a C-terminal PHD finger.

PHD finger found in bromodomain adjacent to zinc finger domain protein 2A (BAZ2A) and 2B (BAZ2B); BAZ2A, also termed transcription termination factor I-interacting protein 5 (TTF-I-interacting protein 5, or Tip5), or WALp3, is an epigenetic regulator. It has been implicated in epigenetic rRNA gene silencing, as the large subunit of the SNF2h-containing chromatin-remodeling complex NoRC that induces nucleosome sliding in an ATP- and histone H4 tail-dependent fashion. BAZ2A has also been shown to be broadly overexpressed in prostate cancer, to regulate numerous protein-coding genes and to cooperate with EZH2 (enhancer of zeste homolog 2) to maintain epigenetic silencing at genes repressed in prostate cancer metastasis. Its overexpression is tightly associated with a prostate cancer subtype displaying CpG island methylator phenotype (CIMP) in tumors and with prostate cancer recurrence in patients. BAZ2B, also termed WALp4, is a bromodomain-containing protein whose biological role is still elusive. It shows high sequence similarly with BAZ2A. Both BAZ2A and BAZ2B contain a TAM (TIP5/ARBP/MBD) domain, a DDT domain, four AT-hooks, BAZ 1 and BAZ 2 motifs, a WAKZ (WSTF/Acf1/KIAA0314/ZK783.4) motif, a plant homeodomain (PHD) finger, and a bromodomain. BAZ2B also harbors an extra Apolipophorin-III like domain in its N-terminal region.

PHD finger 2 found in d4 gene family proteins; The family includes proteins coded by three members of the d4 gene family, DPF1 (neuro-d4), DPF2 (ubi-d4/Requiem), and DPF3 (cer-d4), which function as transcription factors and are involved in transcriptional regulation of genes by changing the condensed/decondensed state of chromatin in the nucleus. DPF2 is ubiquitously expressed and it acts as a transcription factor that may participate in developmentally programmed cell death. DPF1 and DPF3 are expressed predominantly in neural tissues, and they may be involved in the transcription regulation of neuro-specific gene clusters. The d4 family proteins show distinct domain organization with domain 2/3 in the N-terminal region, a Cys2His2 (C2H2) zinc finger or Kruppel-type zinc finger in the central part and two adjacent plant homeodomain (PHD) fingers (d4-domain) in the C-terminal part of the molecule.

PHD finger 3 found in nuclear receptor-binding SET domain-containing (NSD) proteins; The nuclear receptor binding SET domain (NSD) protein is a family of three HMTases, NSD1, NSD2/MMSET/WHSC1, and NSD3/WHSC1L1, that are critical in maintaining chromatin integrity. Reducing NSD activity through specific lysine-HMTase inhibitors appears promising to help suppress cancer growth. NSD proteins have specific mono- and dimethylase activities for H3K36, and they play non-redundant roles during development. NSD1 plays a role in several pathologies, including but not limited to Sotos and Weaver syndromes, acute myeloid leukemia, breast cancer, neuroblastoma, and glioblastoma formation. NSD2 is involved in cancer cell proliferation, survival, and tumor growth, by mediating constitutive NF-kappaB signaling via the cytokine autocrine loop. NSD3 is amplified in human breast cancer cell lines. Moreover, translocation resulting in NUP98 fusion to NSD3 leads to the development of acute myeloid leukemia. NSD proteins contain a catalytic suppressor of variegation, enhancer of zeste and trithorax (SET) domain, two proline-tryptophan-tryptophan-proline (PWWP) domains, five plant homeodomain (PHD) fingers, and an NSD-specific Cys-His rich domain (Cys5HisCysHis). This model corresponds to the third PHD finger.

It is a component of a large complex that acts as a coactivator of multiple transcription factors, including the bile acid (BA)-activated nuclear receptor, farnesoid X receptor (FXR), a critical player in BA homeostasis. The MLL3 complex is essential for p53 transactivation of small heterodimer partner (SHP). KMT2C is also a part of activating signal cointegrator-2 (ASC-2)-containing complex (ASCOM) that contains the transcriptional coactivator nuclear receptor coactivator 6 (NCOA6), KMT2C and its paralog MLL4. The ASCOM complex is critical for nuclear receptor (NR) activation of bile acid transporter genes and is down regulated in cholestasis. KMT2C contains several plant homeodomain (PHD) fingers, two extended PHD (ePHD) fingers, Cys2HisCys5HisCys2His, an ATPase alpha beta signature, a high mobility group (HMG)-1 box, a SET (Suppressor of variegation, Enhancer of zeste, Trithorax) domain and two FY (phenylalanine tyrosine)-rich domains. This model corresponds to the third PHD finger.

PHD finger found in protein BS69; Protein BS69, also termed zinc finger MYND domain-containing protein 11 (ZMYND11 or ZMY11), is a ubiquitously expressed nuclear protein acting as a transcriptional co-repressor in association with various transcription factors. It was originally identified as an adenovirus 5 E1A-binding protein that inhibits E1A transactivation, as well as c-Myb transcription. It also mediates repression, at least in part, through interaction with the co-repressor N-CoR. Moreover, it interacts with Toll-interleukin 1 receptor domain (TIR)-containing adaptor molecule-1 (TICAM-1, also named TRIF) to facilitate NF-kappaB activation and type I IFN induction. It associates with PIAS1, a SUMO E3 enzyme, and Ubc9, a SUMO E2 enzyme, and plays an inhibitory role in muscle and neuronal differentiation. Moreover, BS69 regulates Epstein-Barr virus (EBV) latent membrane protein 1 (LMP1)/C-terminal activation region 2 (CTAR2)-mediated NF-kappaB activation by interfering with the complex formation between TNFR-associated death domain protein (TRADD) and LMP1/CTAR2. It also cooperates with tumor necrosis factor receptor (TNFR)-associated factor 3 (TRAF3) in the regulation of EBV-derived LMP1/CTAR1-induced NF-kappaB activation. Furthermore, BS69 is involved in the p53-p21Cip1-mediated senescence pathway. BS69 contains a plant homeodomain (PHD) finger, a bromodomain, a proline-tryptophan-tryptophan-proline (PWWP) domain, and a Myeloid translocation protein 8, Nervy and DEAF-1 (MYND) domain.

PHD finger found in PHD finger protein 20 (PHF20); PHF20, also termed Glioma-expressed antigen 2, or hepatocellular carcinoma-associated antigen 58, or novel zinc finger protein, or transcription factor TZP (referring to Tudor and zinc finger domain containing protein), is a regulator of NF-kappaB activation by disrupting recruitment of PP2A to p65. It also functions as a transcription factor that binds Akt and plays a role in Akt cell survival/growth signaling. Moreover, it transcriptionally regulates p53. The phosphorylation of PHF20 on Ser291 mediated by protein kinase B (PKB) is essential in tumorigenesis via the regulation of p53 mediated signaling. PHF20 contains an N-terminal malignant brain tumor (MBT) domain, two Tudor domains, a plant homeodomain (PHD) finger and the putative DNA-binding domains, AT hook and Cys2His2-type zinc finger.

PHD finger found in inhibitor of growth protein 3 (ING3) and similar proteins; ING3, also termed p47ING3, is one member of the inhibitor of growth (ING) family of type II tumor suppressors. It is ubiquitously expressed and has been implicated in transcription modulation, cell cycle control, and the induction of apoptosis. It is an important subunit of human NuA4 histone acetyltransferase complex, which regulates the acetylation of histones H2A and H4. Moreover, ING3 promotes ultraviolet (UV)-induced apoptosis through the Fas/caspase-8-dependent pathway in melanoma cells. It physically interacts with subunits of E3 ligase Skp1-Cullin-F-boxprotein complex (SCF complex) and is degraded by the SCF (F-box protein S-phase kinase-associated protein 2, Skp2)-mediated ubiquitin-proteasome system. It also acts as a suppression factor during tumorigenesis and progression of hepatocellular carcinoma (HCC). ING3 contains an N-terminal ING domain and a C-terminal plant homeodomain (PHD) finger.
