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 the transcriptional intermediary factor 1 (TIF1) family and similar proteins; The TIF1 family of transcriptional cofactors includes TIF1alpha (TRIM24), TIF1beta (TRIM28), TIF1gamma (TRIM33), and TIF1delta (TRIM66), which are characterized by an N-terminal RING-finger B-box coiled-coil (RBCC/TRIM) motif and plant homeodomain (PHD) finger followed by a bromodomain in the C-terminal region. TIF1 proteins couple chromatin modifications to transcriptional regulation, signaling, and tumor suppression. They exert a deacetylase-dependent silencing effect when tethered to a promoter region. TIF1alpha, TIF1beta, and TIF1delta can homodimerize and contain a PXVXL motif necessary and sufficient for heterochromatin protein 1(HP1) binding. TIF1alpha and TIF1beta bind nuclear receptors and Kruppel-associated boxes (KRAB) specifically and respectively. In contrast, TIF1delta appears to lack nuclear receptor- and KRAB-binding activity. Moreover, TIF1delta is specifically involved in heterochromatin-mediated gene silencing during postmeiotic phases of spermatogenesis. TIF1gamma is structurally closely related to TIF1alpha and TIF1beta, but has very little functional features in common with them. It does not interact with the KRAB silencing domain of KOX1 or the heterochromatinic proteins HP1alpha, beta, and gamma. It cannot bind to nuclear receptors (NRs). This family also includes Sp100/Sp140 family proteins, the nuclear body SP100 and SP140. Sp110 is a leukocyte-specific component of the nuclear body. It may function as a nuclear hormone receptor transcriptional coactivator that may play a role in inducing differentiation of myeloid cells. It is also involved in resisting intracellular pathogens and functions as an important drug target for preventing intracellular pathogen diseases, such as tuberculosis, hepatic veno-occlusive disease, and intracellular cancers. SP140 is an interferon inducible nuclear leukocyte-specific protein involved in primary biliary cirrhosis and a risk factor in chronic lymphocytic leukemia. It is also implicated in innate immune response to human immunodeficiency virus type 1 (HIV-1) by binding to the virus viral infectivity factor (Vif) protein. Both Sp110 and Sp140 contain a SAND domain, a plant homeodomain (PHD) finger, and a bromodomain (BRD).

PHD finger found in transcription intermediary factor 1-alpha (TIF1-alpha); TIF1-alpha, also termed tripartite motif-containing protein 24 (TRIM24), or E3 ubiquitin-protein ligase TRIM24, or RING finger protein 82, belongs to the TRIM/RBCC protein family. It interacts specifically and in a ligand-dependent manner with the ligand binding domain (LBD) of several nuclear receptors (NRs), including retinoid X (RXR), retinoic acid (RAR), vitamin D3 (VDR), estrogen (ER), and progesterone (PR) receptors. It also associates with heterochromatin-associated factors HP1alpha, MOD1 (HP1beta) and MOD2 (HP1gamma), as well as vertebrate Kruppel-type (C2H2) zinc finger proteins that contain transcriptional silencing domain KRAB. TIF1-alpha is a ligand-dependent co-repressor of retinoic acid receptor (RAR) that interacts with multiple nuclear receptors in vitro via an LXXLL motif, and further acts as a gatekeeper of liver carcinogenesis. It also functions as an E3-ubiquitin ligase targeting p53 and is broadly associated with chromatin silencing. Moreover, it is a chromatin regulator that recognizes specific, combinatorial histone modifications through its C-terminal plant homeodomain (PHD)-Bromodomain (Bromo) region. In addition, it interacts with chromatin and estrogen receptor to activate estrogen-dependent genes associated with cellular proliferation and tumor development. TIF1-alpha contains an N-terminal RBCC (RING finger, B-box zinc-fingers, coiled-coil), a plant homeodomain (PHD) finger, followed by a bromodomain in the C-terminal region.

PHD finger 1 found in PHD finger protein 12 (PHF12); PHF12, also termed PHD factor 1 (Pf1), is a plant homeodomain (PHD) zinc finger-containing protein that bridges the transducin-like enhancer of split (TLE) corepressor to the mSin3A-histone deacetylase (HDAC)-complex, and further represses transcription at targeted genes. PHF12 also interacts with MRG15 (mortality factor-related genes on chromosome 15), a member of the mortality factor (MORF) family of proteins implicated in regulating cellular senescence. PHF12 contains two plant-homeodomain (PHD) zinc fingers followed by a polybasic region. The PHD fingers function downstream of phosphoinositide signaling triggered by the interaction between polybasic regions and phosphoinositides. This model corresponds to the first PHD finger.

PHD finger found in transcriptional intermediary factor 1 gamma (TIF1gamma); TIF1gamma, also termed tripartite motif-containing 33 (trim33), or ectodermin, or RFG7, or PTC7, is an E3-ubiquitin ligase that functions as a regulator of transforming growth factor beta (TGFbeta) signaling; it inhibits the Smad4-mediated TGFbeta response by interaction with Smad2/3 or ubiquitylation of Smad4. Moreover, TIF1gamma is an important regulator of transcription during hematopoiesis, as well as a key factor of tumorigenesis. Like other TIF1 family members, TIF1gamma also contains an intrinsic transcriptional silencing function. It can control erythroid cell fate by regulating transcription elongation. It can bind to the anaphase-promoting complex/cyclosome (APC/C) and promotes mitosis. TIF1gamma contains an N-terminal RBCC (RING finger, B-box zinc-fingers, coiled-coil), a plant homeodomain (PHD) finger, followed by a bromodomain in the C-terminal region.

PHD finger 1 found in Lysine-specific demethylase KDM5A, KDM5B, KDM5C, KDM5D and similar proteins; The JARID subfamily within the JmjC proteins includes Lysine-specific demethylase KDM5A, KDM5B, KDM5C, KDM5D and a Drosophila homolog, protein little imaginal discs (Lid). 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 interacting 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. KDM5C is a H3K4 trimethyl-histone demethylase that catalyzes demethylation of H3K4me3 and H3K4me2 to H3K4me1. It plays a role in neuronal survival and dendrite development. KDM5C defects are associated with X-linked mental retardation (XLMR). KDM5D is a male-specific antigen that shows a demethylase activity specific for di- and tri-methylated histone H3K4 (H3K4me2 and H3K4me3), and has a male-specific function as a histone H3K4 demethylase by recruiting a meiosis-regulatory protein, MSH5, to condensed DNA. KDM5D directly interacts with a polycomb-like protein Ring6a/MBLR, and plays a role in regulation of transcriptional initiation through H3K4 demethylation. This family also includes Drosophila melanogaster protein little imaginal discs (Lid) that functions as a JmjC-dependent H3K4me3 demethylase, which is required for dMyc-induced cell growth. It positively regulates Hox gene expression in S2 cells. Members in this family contain the catalytic JmjC domain, JmjN, the BRIGHT domain, which is an AT-rich interacting domain (ARID), and a Cys5HisCys2 zinc finger, as well as two or three plant homeodomain (PHD) fingers.

It possesses intrinsic HAT activity to acetylate both itself and lysine (K) residues on histone H2B, histone H3 (K14) and histone H4 (K5, K8, K12 and K16) in vitro and H3K9 in vivo. MOZ-related factor (MORF), also termed MOZ2, or histone acetyltransferase KAT6B, or MOZ, YBF2/SAS3, SAS2 and TIP60 protein 4 (MYST4), is a ubiquitously expressed transcriptional regulator with intrinsic HAT activity. It can interact with the Runt-domain transcription factor Runx2 and form a tetrameric complex with BRPFs, ING5, and EAF6. Both MOZ and MORF are catalytic subunits of HAT complexes that are required for normal developmental programs, such as hematopoiesis, neurogenesis, and skeletogenesis, and are also implicated in human leukemias. MOZ is also the catalytic subunit of a tetrameric inhibitor of growth 5 (ING5) complex, which specifically acetylates nucleosomal histone H3K14. Moreover, MOZ and MORF are involved in regulating transcriptional activation mediated by Runx2 (or Cbfa1), a Runt-domain transcription factor known to play important roles in T cell lymphomagenesis and bone development, and its homologs. MOZ contains a linker histone 1 and histone 5 domains and two plant homeodomain (PHD) fingers. In contrast, MORF contains an N-terminal region containing two PHD fingers, a putative HAT domain, an acidic region, and a C-terminal Ser/Met-rich domain. The family corresponds to the first PHD finger.

It has a restricted expression pattern in the testis, ovary, and transiently in the mammary gland of pregnant females 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.

PHD finger 1 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 first PHD finger.

PHD finger 5 found in Histone-lysine N-methyltransferase 2C (KMT2C) and PHD finger 4 found in KMT2D; KMT2C, also termed myeloid/lymphoid or mixed-lineage leukemia protein 3 (MLL3), or homologous to ALR protein, is a histone H3 lysine 4 (H3K4) lysine methyltransferase that functions as a circadian factor contributing to genome-scale circadian transcription. 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. KMT2D, also termed ALL1-related protein (ALR), is encoded by the gene that was named MLL4, a fourth human homolog of Drosophila trithorax, located on chromosome 12. It enzymatically generates trimethylated histone H3 Lysine 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 as HOXA1-3 and NESTIN. KMT2D is also a part of ASCOM. Both KMT2C and KMT2D contain the catalytic domain SET, several plant homeodomain (PHD) fingers, 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 fifth PHD finger of KMT2C and the fourth PHD finger of KMT2D.

PHD finger found in ubiquitin-like PHD and RING finger domain-containing protein UHRF1 and UHRF2; UHRF1 is a unique chromatin effector protein that integrates the recognition of both histone PTMs and DNA methylation. It is essential for cell proliferation and plays a critical role in the development and progression of many human carcinomas, such as laryngeal squamous cell carcinoma (LSCC), gastric cancer (GC), esophageal squamous cell carcinoma (ESCC), colorectal cancer, prostate cancer, and breast cancer. UHRF1 acts as a transcriptional repressor through its binding to histone H3 when it is unmodified at Arg2. Its overexpression in human lung fibroblasts results in downregulation of expression of the tumour suppressor pRB. It also plays a role in transcriptional repression of the cell cycle regulator p21. Moreover, UHRF1-dependent repression of transcription factors can facilitate the G1-S transition. It interacts with Tat-interacting protein of 60 kDa (TIP60) and induces degradation-independent ubiquitination of TIP60. It is also an N-methylpurine DNA glycosylase (MPG)-interacting protein that binds MPG in a p53 status-independent manner in the DNA base excision repair (BER) pathway. In addition, UHRF1 functions as an epigenetic regulator that is important for multiple aspects of epigenetic regulation, including maintenance of DNA methylation patterns and recognition of various histone modifications. 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. Both UHRF1 and UHRF2 contain 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 Remodeling and spacing factor 1 (Rsf-1); Rsf-1, also termed HBV pX-associated protein 8, or Hepatitis B virus X-associated protein alpha (HBxAPalpha), or p325 subunit of RSF chromatin-remodeling complex, is a novel nuclear protein with histone chaperon function. It is a subunit of an ISWI chromatin remodeling complex, remodeling and spacing factor (RSF), and plays a role in mediating ATPase-dependent chromatin remodeling and conferring tumor aggressiveness in common carcinomas. As an ataxia-telangiectasia mutated (ATM)-dependent chromatin remodeler, Rsf-1 facilitates DNA damage checkpoints and homologous recombination repair. It regulates the mitotic spindle checkpoint and chromosome instability through the association with serine/threonine kinase BubR1 (BubR1) and Hepatitis B virus (HBV) X protein (HBx) in the chromatin fraction during mitosis. It also interacts with cyclin E1 and promotes tumor development. Rsf-1 contains a plant homeodomain (PHD) finger.

PHD finger found in transcription intermediary factor 1-beta (TIF1-beta); TIF1-beta, also termed Kruppel-associated Box (KRAB)-associated protein 1 (KAP-1), or KRAB-interacting protein 1 (KRIP-1), or nuclear co-repressor KAP-1, or RING finger protein 96, or tripartite motif-containing protein 28 (TRIM28), or E3 SUMO-protein ligase TRIM28, acts as a nuclear co-repressor that plays a role in transcription and in DNA damage response. Upon DNA damage, the phosphorylation of KAP-1 on serine 824 by the ataxia telangiectasia-mutated (ATM) kinase enhances cell survival and facilitates chromatin relaxation and heterochromatic DNA repair. It also regulates CHD3 nucleosome remodeling during DNA double-strand break (DSB) response. Meanwhile, KAP-1 can be dephosphorylated by protein phosphatase PP4C in the DNA damage response. In addition, KAP-1 is a co-activator of the orphan nuclear receptor NGFI-B (or Nur77) and is involved in NGFI-B-dependent transcription. It is also a coiled-coil binding partner, substrate and activator of the c-Fes protein tyrosine kinase. TIF1-beta contains an N-terminal RBCC (RING finger, B-box zinc-fingers, coiled-coil), which can interact with KRAB zinc finger proteins (KRAB-ZFPs), MDM2, MM1, C/EBPbeta, and mediates homo- and heterodimerization, a plant homeodomain (PHD) finger followed by a bromodomain in the C-terminal region, which interact with SETDB1, Mi-2alpha and other proteins to form complexes with histone deacetylase or methyltransferase activity.

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 the inhibitor of growth (ING) protein family; The ING family includes a group of tumor suppressors, ING1-5, which act as readers and writers of the histone epigenetic code, affecting DNA damage response, chromatin remodeling, cellular senescence, differentiation, cell cycle regulation and apoptosis. They may have a general role in mediating the cellular response to genotoxic stress through binding to and regulating the activities of histone acetyltransferase (HAT) and histone deacetylase (HDAC) chromatin remodeling complexes. All ING proteins contain an N-terminal ING domain and a C-terminal plant homeodomain (PHD) finger.

PHD finger 1 found in polycomb repressive complex 2 (PRC2)-associated polycomb-like (PCL) family proteins MTF2, PHF19, and similar proteins; The family includes two PCL family proteins, metal-response element-binding transcription factor 2 (MTF2/PCL2) and PHF19/PCL3, which are homologs of PHD finger protein1 (PHF1). PCL family proteins are accessory components of the polycomb repressive complex 2 (PRC2) core complex and all contain an N-terminal Tudor domain followed by two PHD fingers, and a C-terminal MTF2 domain. They 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 fingers 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 first PHD finger.

PHD finger found in BRPF proteins, Jade proteins, protein AF-10, AF-17, and similar proteins; The family includes BRPF proteins, Jade proteins, protein AF-10 and AF-17. BRPF proteins are scaffold proteins that form monocytic leukemic zinc-finger protein (MOZ)/MOZ-related factor (MORF) H3 histone acetyltransferase (HAT) complexes with other regulatory subunits, such as inhibitor of growth 5 (ING5) and Esa1-associated factor 6 ortholog (EAF6). BRPF proteins have multiple domains, including a canonical Cys4HisCys3 plant homeodomain (PHD) zinc finger followed by a non-canonical extended PHD (ePHD) finger, Cys2HisCys5HisCys2His, a bromodomain and a proline-tryptophan-tryptophan-proline (PWWP) domain. PHD and ePHD fingers both bind to lysine 4 of histone H3 (K4H3), bromodomains interact with acetylated lysines on N-terminal tails of histones and other proteins, and PWWP domains show histone-binding and chromatin association properties. Jade proteins are required for ING4 and ING5 to associate with histone acetyltransferase (HAT) HBO1 and EAF6, to form a HBO1 complex that has a histone H4-specific acetyltransferase activity, a reduced activity toward histone H3, and is responsible for the bulk of histone H4 acetylation in vivo. AF-10, also termed ALL1 (acute lymphoblastic leukemia)-fused gene from chromosome 10 protein, is a transcription factor that has been implicated in the development of leukemia following chromosomal rearrangements between the AF10 gene and one of at least two other genes, MLL and CALM. AF-17, also termed ALL1-fused gene from chromosome 17 protein, is a putative transcription factor that may play a role in multiple signaling pathways. All Jade proteins, AF-10, and AF-17 contain a canonical PHD finger followed by a non-canonical ePHD finger. This model corresponds to the canonical PHD finger.

PHD finger found in protein Jade-1 and similar proteins; Jade-1, also termed PHD finger protein 17 (PHF17), is a novel binding partner of von Hippel-Lindau (VHL) tumor suppressor Pvhl, a key regulator of the cellular oxygen sensing pathway. It is highly expressed in renal proximal tubules. Jade-1 functions as an essential regulator of multiple cell signaling pathways. It may be involved in the serine/threonine kinase AKT/AKT1 pathway during renal cancer pathogenesis and normally prevents renal epithelial cell proliferation and transformation. It also acts as a pro-apoptotic and growth suppressive ubiquitin ligase to inhibit canonical Wnt downstream effector beta-catenin for proteasomal degradation, and as a transcription factor associated with histone acetyltransferase activity and with increased abundance of cyclin-dependent kinase inhibitor p21. Moreover, Jade-1 is required for ING4 and ING5 to associate with histone acetyltransferase (HAT) HBO1 and Eaf6 to form a HBO1 complex, and plays a role in epithelial cell regeneration. It has also been identified as a novel component of the nephrocystin protein (NPHP) complex and interacts with the ciliary protein nephrocystin-4 (NPHP4). Jade-1 contains a canonical Cys4HisCys3 plant homeodomain (PHD) finger followed by a non-canonical extended PHD (ePHD) finger, Cys2HisCys5HisCys2His, both of which are zinc-binding motifs. This model corresponds to the canonical Cys4HisCys3 PHD finger.
