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.

TolA protein; TolA couples the inner membrane complex of itself with TolQ and TolR to the outer membrane complex of TolB and OprL (also called Pal). Most of the length of the protein consists of low-complexity sequence that may differ in both length and composition from one species to another, complicating efforts to discriminate TolA (the most divergent gene in the tol-pal system) from paralogs such as TonB. Selection of members of the seed alignment and criteria for setting scoring cutoffs are based largely conserved operon struction. //The Tol-Pal complex is required for maintaining outer membrane integrity. Also involved in transport (uptake) of colicins and filamentous DNA, and implicated in pathogenesis. Transport is energized by the proton motive force. TolA is an inner membrane protein that interacts with periplasmic TolB and with outer membrane porins ompC, phoE and lamB. [Transport and binding proteins, Other, Cellular processes, Pathogenesis]

first PWWP domain found in nuclear SET domain-containing protein 2 (NSD2) and similar proteins; NSD2, also called histone-lysine N-methyltransferase NSD2, multiple myeloma SET domain-containing protein (MMSET), or protein trithorax-5 Wolf-Hirschhorn syndrome candidate 1 protein (WHSC1), is overexpressed frequently in the t(4;14) translocation in 15% to 20% of multiple myeloma. It plays important roles in cancer cell proliferation, survival, and tumor growth, through mediating constitutive NF-kappaB signaling via the cytokine autocrine loop. It also enhances androgen receptor (AR)-mediated transcription. The principal chromatin-regulatory activity of NSD2 is dimethylation of histone H3 at lysine 36 (H3K36me2). NSD2 contains a catalytic suppressor of variegation, enhancer of zeste and trithorax (SET) domain, two proline-tryptophan-tryptophan-prolin motif (PWWP) domains, a high mobility group (HMG) box, five PHD (plant-homeodomain) zinc finger motifs, and an NSD-specific Cys-His rich domain (C5HCH). The SET domain is responsible for histone methyltransferase activity. The PWWP, HMG, and PHD domains mediate chromatin interaction and recognition of histone marks. This model corresponds to the first PWWP domain. The PWWP domain specifically recognizes DNA and histone methylated lysines.

It plays a role in several pathologies, including but not limited to Sotos and Weaver syndromes, acute myeloid leukemia, breast cancer, neuroblastoma, and glioblastoma formation. It can alter transcription by interacting with the protein NSD1-interacting zinc finger protein 1 (NIZP1). It also mitigates caspase-1 activation by listeriolysin o (LLO) in macrophages, and requires functional LLO for the regulation of IL-1beta secretion. Moreover, NSD1 regulates RNA polymerase II (RNAP II) recruitment to bone morphogenetic protein 4 (BMP4). NSD1 contains 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 (C5HCH).

PWWP domain; The PWWP domain is named after a conserved Pro-Trp-Trp-Pro motif. The domain binds to Histone-4 methylated at lysine-20, H4K20me, suggesting that it is methyl-lysine recognition motif. Removal of two conserved aromatic residues in a hydrophobic cavity created by this domain within the full-length protein, Pdp1, abolishes the interaction o f the protein with H4K20me3. In fission yeast, Set9 is the sole enzyme that catalyzes all three states of H4K20me, and Set9-mediated H4K20me is required for efficient recruitment of checkpoint protein Crb2 to sites of DNA damage. The methylation of H4K20 is involved in a diverse array of cellular processes, such as organizing higher-order chromatin, maintaining genome stability, and regulating cell-cycle progression.

PHD finger 3 found in nuclear receptor-binding SET domain-containing protein 1 (NSD1); NSD1, also termed H3 Lysine-36 and H4 Lysine-20 specific histone-lysine N-methyltransferase, or androgen receptor coactivator 267 kDa protein, or androgen receptor-associated protein of 267 kDa, or H3-K36-HMTase H4-K20-HMTase, or Lysine N-methyltransferase 3B (KMT3B), or NR-binding SET domain-containing protein, is a lysine methyltransferase that preferentially methylates H3 on Lysine36 (H3-K36) and H4 on Lysine20 (H4-K20), which is primarily associated with active transcription. It plays a role in several pathologies, including but not limited to Sotos and Weaver syndromes, acute myeloid leukemia, breast cancer, neuroblastoma, and glioblastoma formation. It can alter transcription by interacting with the protein NSD1-interacting zinc finger protein 1 (NIZP1). It also mitigates caspase-1 activation by listeriolysin o (LLO) in macrophages, and requires functional LLO for the regulation of IL-1beta secretion. Moreover, NSD1 regulates RNA polymerase II (RNAP II) recruitment to bone morphogenetic protein 4 (BMP4). NSD1 contains 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). The SET domain is responsible for histone methyltransferase activity. The PWWP and PHD fingers are involved in protein-protein interactions. This model corresponds to the third PHD finger.

PHD finger 4 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 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).

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.

PHD finger 2 found in monocytic leukemia zinc-finger protein (MOZ) and its factor (MORF); MOZ, also termed histone acetyltransferase KAT6A, YBF2/SAS3, SAS2 and TIP60 protein 3 (MYST-3), or runt-related transcription factor-binding protein 2, or zinc finger protein 220, is a MYST-type histone acetyltransferase (HAT) that functions as a coactivator for acute myeloid leukemia 1 protein (AML1)- and p53-dependent transcription. 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.

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.

It alters the remodeling properties of the ATPase motor protein sucrose nonfermenting-2 homolog (SNF2H). Moreover, BAZ1A and its complexes play important roles in DNA double-strand break (DSB) repair. It is essential for averting improper gene expression during spermatogenesis. It also regulates transcriptional repression of vitamin D3 receptor-regulated genes. BAZ1B, also termed Tyrosine-protein kinase BAZ1B, or Williams syndrome transcription factor (WSTF), or Williams-Beuren syndrome chromosomal region 10 protein, Williams-Beuren syndrome chromosomal region 9 protein, or WALp2, is a multifunctional protein implicated in several nuclear processes, including replication, transcription, and the DNA damage response. BAZ1B/WSTF, together with the imitation switch (ISWI) ATPase, forms a WSTF-ISWI chromatin remodeling complex (WICH), which transiently associates with the human inactive X chromosome (Xi) during late S-phase prior to BRCA1 and gamma-H2AX. Moreover, BAZ1B/WSTF, SNF2h, and nuclear myosin 1 (NM1) forms the chromatin remodeling complex B-WICH that is involved in regulating rDNA transcription. Both BAZ1A and BAZ1B contain a WAC motif, a DDT domain, BAZ 1 and BAZ 2 motifs, a WAKZ (WSTF/Acf1/KIAA0314/ZK783.4) motif, a plant homeodomain (PHD) finger, and a bromodomain.

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.

TolA protein; TolA couples the inner membrane complex of itself with TolQ and TolR to the outer membrane complex of TolB and OprL (also called Pal). Most of the length of the protein consists of low-complexity sequence that may differ in both length and composition from one species to another, complicating efforts to discriminate TolA (the most divergent gene in the tol-pal system) from paralogs such as TonB. Selection of members of the seed alignment and criteria for setting scoring cutoffs are based largely conserved operon struction. //The Tol-Pal complex is required for maintaining outer membrane integrity. Also involved in transport (uptake) of colicins and filamentous DNA, and implicated in pathogenesis. Transport is energized by the proton motive force. TolA is an inner membrane protein that interacts with periplasmic TolB and with outer membrane porins ompC, phoE and lamB. [Transport and binding proteins, Other, Cellular processes, Pathogenesis]

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.

Extended PHD finger 2 found in histone-lysine N-methyltransferase 2C (KMT2C) and 2D (KMT2D); The extended plant homeodomain (ePHD) zinc finger is characterized as Cys2HisCys5HisCys2His. This model corresponds to the second ePHD finger of KMT2C, and 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, five PHD fingers, two ePHD fingers, a RING finger, an HMG (high-mobilitygroup)-binding motif, and two FY-rich regions.

PWWP domain found in protein BS69 and similar proteins; Protein BS69, also called 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. The PWWP domain specifically recognizes DNA and histone methylated lysines.

PHD finger found in transcriptional intermediary factor 1 delta (TIF1delta); TIF1delta, also termed tripartite motif-containing protein 66 (TRIM66), is a novel heterochromatin protein 1 (HP1)-interacting member of the transcriptional intermediary factor1 (TIF1) family expressed by elongating spermatids. Like other TIF1 proteins, TIF1delta displays a potent trichostatin A (TSA)-sensitive repression function; TSA is a specific inhibitor of histone deacetylases. Moreover, TIF1delta plays an important role in heterochromatin-mediated gene silencing during postmeiotic phases of spermatogenesis. It functions as a negative regulator of postmeiotic genes acting through HP1 isotype gamma (HP1gamma) complex formation and centromere association. TIF1delta 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 found in inhibitor of growth protein 1 (ING1); ING1 is an epigenetic regulator and a type II tumor suppressor that impacts cell growth, aging, apoptosis, and DNA repair, by affecting chromatin conformation and gene expression. It acts as a reader of the active chromatin mark, the trimethylation of histone H3 lysine 4 (H3K4me3). It binds and directs Growth arrest and DNA damage inducible protein 45 a (Gadd45a) to target sites, thus linking the histone code with DNA demethylation. It interacts with the proliferating cell nuclear antigen (PCNA) via the PCNA-interacting protein (PIP) domain in a UV-inducible manner. It also interacts with a PCNA-interacting protein, p15 (PAF). Moreover, ING1 associates with members of the 14-3-3 family, which is necessary for the cytoplasmic relocalization. Endogenous ING1 protein specifically interacts with the pro-apoptotic BCL2 family member BAX and colocalizes with BAX in a UV-inducible manner. It stabilizes the p53 tumor suppressor by inhibiting polyubiquitination of multi-monoubiquitinated forms via interaction with and colocalization of the herpesvirus-associated ubiquitin-specific protease (HAUSP)-deubiquitinase with p53. It is also involved in trichostatin A-induced apoptosis and caspase 3 signaling in p53-deficient glioblastoma cells. In addition, tyrosine kinase Src can bind phosphorylate ING1 and further regulates its activity. ING1 contains an N-terminal ING domain and a C-terminal plant homeodomain (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.
