Williams-Beuren syndrome DDT (WSD), D-TOX E motif; This family represents the combined alpha-helical module found in diverse eukaryotic chromatin proteins. Based on the Ioc3 structure, the N-terminus of this module is inferred to interact with nucleosomal linker DNA and the SLIDE domain of ISWI proteins. The resulting complex forms a protein ruler that measures out the spacing between two adjacent nucleosomes. The acidic residue from the GxD signature at the N-terminus is a major determinant of the interaction between the ISWI and WHIM motifs. The N-terminal portion also contacts the inter-nucleosomal linker DNA. The module shows a great domain architectural diversity and is often combined with other modified histone peptide recognizing and DNA binding domains, some of which discriminate methylated DNA. The WSD module constitutes the inter-nucleosomal linker DNA binding site in the major groove of DNA, and was first identified as WSD, the D-TOX E motif of plant homeodomains homologous with the mutant transcription factor causing Williams-Beuren syndrome in association with the DDT-domain.

PHD finger found in bromodomain adjacent to zinc finger domain protein 2A (BAZ2A); 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. It contains 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.

Methyl-CpG binding domain; The Methyl-CpG binding domain (MBD) binds to DNA that contains one or more symmetrically methylated CpGs. DNA methylation in animals is associated with alterations in chromatin structure and silencing of gene expression. MBD has negligible non-specific affinity for DNA. In vitro foot-printing with MeCP2 showed the MBD can protect a 12 nucleotide region surrounding a methyl CpG pair. MBDs are found in several Methyl-CpG binding proteins and also DNA demethylase.

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.

DDT domain; The DDT domain is named after (DNA binding homeobox and Different Transcription factors) and is approximately 60 residues in length. Along with the WHIM motifs, it comprises an entirely alpha helical module found in diverse eukaryotic chromatin proteins. Based on the structure of Ioc3, this module is inferred to interact with nucleosomal linker DNA and the SLIDE domain of ISWI proteins. The resulting complex forms a protein ruler that measures out the spacing between two adjacent nucleosomes. In particular, the DDT domain, in combination with the WHIM1 and WHIM2 motifs form the SLIDE domain binding pocket.

Bromodomain; tif1_like subfamily. Tif1 (transcription intermediary factor 1) is a member of the tripartite motif (TRIM) protein family, which is characterized by a particular domain architecture. It functions by recruiting coactivators and/or corepressors to modulate transcription. Vertebrate Tif1-gamma, also labeled E3 ubiquitin-protein ligase TRIM33, plays a role in the control of hematopoiesis. Its homologue in Xenopus laevis, Ectodermin, has been shown to function in germ-layer specification and control of cell growth during embryogenesis. Bromodomains are 110 amino acid long domains, that are found in many chromatin associated proteins. Bromodomains can interact specifically with acetylated lysine.

MeCP2, MBD1, MBD2, MBD3, MBD4, CLLD8-like, and BAZ2A-like proteins constitute a family of proteins that share the methyl-CpG-binding domain (MBD). The MBD consists of about 70 residues and is defined as the minimal region required for binding to methylated DNA by a methyl-CpG-binding protein which binds specifically to methylated DNA. The MBD can recognize a single symmetrically methylated CpG either as naked DNA or within chromatin. MeCP2, MBD1 and MBD2 (and likely MBD3) form complexes with histone deacetylase and are involved in histone deacetylase-dependent repression of transcription. MBD4 is an endonuclease that forms a complex with the DNA mismatch-repair protein MLH1. The MBDs present in putative chromatin remodelling subunit, BAZ2A, and putative histone methyltransferase, CLLD8, represent two phylogenetically distinct groups within the MBD protein family.

PHD finger found in bromodomain adjacent to zinc finger domain protein 1A (BAZ1A); BAZ1A, also termed ATP-dependent chromatin-remodeling protein, or ATP-utilizing chromatin assembly and remodeling factor 1 (ACF1), or CHRAC subunit ACF1, or Williams syndrome transcription factor-related chromatin-remodeling factor 180 (WCRF180), or WALp1, is a subunit of the conserved imitation switch (ISWI)-family ATP-dependent chromatin assembly and remodeling factor (ACF)/chromatin accessibility complex (CHRAC) chromatin remodeling complex, which is required for DNA replication through heterochromatin. 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. BAZ1A contains 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.

Bromodomain; SPT7_like subfamily. SPT7 is a yeast protein that functions as a component of the transcription regulatory histone acetylation (HAT) complexes SAGA, SALSA, and SLIK. SAGA is involved in the RNA polymerase II-dependent transcriptional regulation of about 10% of all yeast genes. The SPT7 bromodomain has been shown to weakly interact with acetylated histone H3, but not H4. The human representative of this subfamily is cat eye syndrome critical region protein 2 (CECR2). Bromodomains are 110 amino acid long domains, that are found in many chromatin associated proteins. Bromodomains can interact specifically with acetylated lysine.

PHD finger 1 found in Schizosaccharomyces pombe Lid2 complex component Lid2p and similar proteins; 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 corresponds to the first PHD finger.

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 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.

PHD finger 1 found in lysine-specific demethylase 5B (KDM5B); KDM5B (also termed Cancer/testis antigen 31 (CT31), Histone demethylase JARID1B, Jumonji/ARID domain-containing protein 1B (JARID1B), 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 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 Lysine-specific demethylase 5C (KDM5C) and 5D (KDM5D); The family includes KDM5C and KDM5D, both of which belong to the JARID subfamily within the JmjC proteins. KDM5C (also termed Histone demethylase JARID1C, Jumonji/ARID domain-containing protein 1C, SmcX, or Xe169) 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 (also termed Histocompatibility Y antigen (H-Y), Histone demethylase JARID1D, Jumonji/ARID domain-containing protein 1D, or SmcY) is a male-specific antigen that shows a demethylase activity specific for di- and tri-methylated histone H3K4 (H3K4me3 andH3K4me2), 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. Both KDM5C and KDM5D 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 plant homeodomain (PHD) fingers. This model corresponds to the first PHD finger.

DDT domain; The DDT domain is named after (DNA binding homeobox and Different Transcription factors) and is approximately 60 residues in length. Along with the WHIM motifs, it comprises an entirely alpha helical module found in diverse eukaryotic chromatin proteins. Based on the structure of Ioc3, this module is inferred to interact with nucleosomal linker DNA and the SLIDE domain of ISWI proteins. The resulting complex forms a protein ruler that measures out the spacing between two adjacent nucleosomes. In particular, the DDT domain, in combination with the WHIM1 and WHIM2 motifs form the SLIDE domain binding pocket.
