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.

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.

F-type ATP synthase, membrane subunit b; Membrane subunit b is a component of the Fo complex of FoF1-ATP synthase. The F-type ATP synthases (FoF1-ATPase) consist of two structural domains: the F1 (assembly factor one) complex containing the soluble catalytic core, and the Fo (oligomycin sensitive factor) complex containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. F1 is composed of alpha (or A), beta (B), gamma (C), delta (D) and epsilon (E) subunits with a stoichiometry of 3:3:1:1:1, while Fo consists of the three subunits a, b, and c (1:2:10-14). An oligomeric ring of 10-14 c subunits (c-ring) make up the Fo rotor. The flux of protons through the ATPase channel (Fo) drives the rotation of the c-ring, which in turn is coupled to the rotation of the F1 complex gamma subunit rotor due to the permanent binding between the gamma and epsilon subunits of F1 and the c-ring of Fo. The F-ATP synthases are primarily found in the inner membranes of eukaryotic mitochondria, in the thylakoid membranes of chloroplasts or in the plasma membranes of bacteria. The F-ATP synthases are the primary producers of ATP, using the proton gradient generated by oxidative phosphorylation (mitochondria) or photosynthesis (chloroplasts). Alternatively, under conditions of low driving force, ATP synthases function as ATPases, thus generating a transmembrane proton or Na(+) gradient at the expense of energy derived from ATP hydrolysis. This group also includes F-ATP synthase that has also been found in the archaea Candidatus Methanoperedens.

PWWP domain found in protein kinase C-binding protein 1 (PRKCBP1) and similar proteins; PRKCBP1, also called cutaneous T-cell lymphoma-associated antigen se14-3 (CTCL-associated antigen se14-3), Rack7, or zinc finger MYND domain-containing protein 8 (ZMYND8), is a novel receptor for activated C-kinase (RACK)-like protein that may play an important role in the activation and regulation of PKC-beta I, and the PKC signaling cascade. It also has been identified as a formin homology-2-domain containing protein 1 (FHOD1)-binding protein that may be involved in FHOD1-regulated actin polymerization and transcription. Moreover, PRKCBP1 may function as a REST co-repressor 2 (RCOR2) interacting factor. They form a RCOR2/ZMYND8 complex which might be involved in the regulation of neural differentiation. PRKCBP1 contains a plant homeodomain (PHD) finger, a bromodomain, and a proline-tryptophan-tryptophan-proline (PWWP) domain. The PWWP domain specifically recognizes DNA and histone methylated lysines.

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 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). This model corresponds to the fourth PHD finger.

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 1 found in class II Chromodomain-Helicase-DNA binding (CHD) proteins; Class II CHD proteins includes chromodomain-helicase-DNA-binding protein CHD3, CHD4, and CHD5, which are nuclear and ubiquitously expressed chromatin remodelling ATPases generally associated with histone deacetylases (HDACs). They are involved in DNA Double Strand Break (DSB) signaling, DSB repair and/or p53-dependent pathways such as apoptosis and senescence, as well as in the maintenance of genomic stability, and/or cancer prevention. They function as subunits of the Nucleosome Remodelling and Deacetylase (NuRD) complex, which is generally associated with gene repression, heterochromatin formation, and overall chromatin compaction. In contrast to the class I CHD enzymes (CHD1 and CHD2), class II CHD proteins lack identifiable DNA-binding domains, but possess a C-terminal coiled-coil region. Moreover, in addition to the tandem chromodomains and a helicase domain, they all harbor tandem plant homeodomain (PHD) zinc fingers involved in the recognition of methylated histone tails. This model corresponds to the first PHD finger.

PHD finger 4 found in nuclear SET domain-containing protein 2 (NSD2); NSD2, also termed histone-lysine N-methyltransferase NSD2, or 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, by 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 fingers, and an NSD-specific Cys-His rich domain (Cys5HisCysHis). The SET domain is responsible for histone methyltransferase activity. The PWWP, HMG, and PHD fingers mediate chromatin interaction and recognition of histone marks. This model corresponds to the fourth PHD finger.

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 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.
