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.

B-box-type 1 zinc finger found in tripartite motif-containing protein 66 (TRIM66) and similar proteins; TRIM66, also termed transcriptional intermediary factor 1 delta (TIF1delta), is a novel heterochromatin protein 1 (HP1)-interacting member of the transcriptional intermediary factor 1 (TIF1) family, and is expressed by elongating spermatids. Like other TIF1 proteins, TRIM66 displays a potent trichostatin A (TSA)-sensitive repression function; TSA is a specific inhibitor of histone deacetylases. Moreover, TRIM66 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. TRIM66 belongs to an unclassified TRIM (tripartite motif) family of proteins that do not have RING fingers and thus lack the characteristic tripartite (RING (R), B-box, and coiled coil (CC)) RBCC motif. The type 1 B-box (Bbox1) zinc finger is characterized by a C6H2 zinc-binding consensus motif.

coiled-coil (CC) domain of Drosophila brain tumor (brat) and similar proteins; This family contains the coiled-coil (CC) region of Drosophila brain tumor (Brat), a translational repressor that belongs to the tripartite motif (TRIM) protein superfamily. TRIM proteins play important roles in various cellular processes and are involved in many diseases which consists of two B-box domains and a coiled-coil (CC) domain at the N-terminal region, and an NHL domain at the C-terminus. Brat localizes at the basal cortex during asymmetric division of Drosophila neuroblasts by directly interacting with the scaffolding protein Miranda (Mira), which it does through the CC-NHL domain tandem, indicating that the function of the Brat CC domain is to assemble Brat-NHL in dimeric form which is necessary for Mira binding. Brat CC forms an elongated antiparallel dimer similar to its other TRIM protein counterparts, but the overall length of Brat CC dimer is shorter than the TRIMs.

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.

B-box-type 1 zinc finger found in tripartite motif-containing protein 66 (TRIM66) and similar proteins; TRIM66, also termed transcriptional intermediary factor 1 delta (TIF1delta), is a novel heterochromatin protein 1 (HP1)-interacting member of the transcriptional intermediary factor 1 (TIF1) family, and is expressed by elongating spermatids. Like other TIF1 proteins, TRIM66 displays a potent trichostatin A (TSA)-sensitive repression function; TSA is a specific inhibitor of histone deacetylases. Moreover, TRIM66 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. TRIM66 belongs to an unclassified TRIM (tripartite motif) family of proteins that do not have RING fingers and thus lack the characteristic tripartite (RING (R), B-box, and coiled coil (CC)) RBCC motif. The type 1 B-box (Bbox1) zinc finger is characterized by a C6H2 zinc-binding consensus motif.

Bromodomain, cbp_like subfamily. Cbp (CREB binding protein or CREBBP) is an acetyltransferase acting on histone, which gives a specific tag for transcriptional activation and also acetylates non-histone proteins. CREBBP binds specifically to phosphorylated CREB protein and augments the activity of phosphorylated CREB to activate transcription of cAMP-responsive genes. Bromodomains are 110 amino acid long domains, that are found in many chromatin associated proteins. Bromodomains can interact specifically with acetylated lysine.

PHD finger 2 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 second PHD finger.

B-box-type 2 zinc finger found in transcription intermediary factor 1 (TIF1) family; This family corresponds to the TIF1 family of transcriptional cofactors including TIF1-alpha (TRIM24), TIF1-beta (TRIM28), and TIF1-gamma (TRIM33), which belong to the C-VI subclass of TRIM (tripartite motif) family of proteins that are defined by their N-terminal RBCC (RING, Bbox, and coiled coil) domains, including three consecutive zinc-binding domains, a RING finger, Bbox1 and Bbox2, and a coiled coil region, as well as a plant homeodomain (PHD), and a bromodomain (Bromo) positioned C-terminal to the RBCC domain. The type 2 B-box (Bbox2) zinc finger is characterized by a CHC3H2 zinc-binding consensus motif. 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 and TIF1beta can homodimerize and contain a PXVXL motif necessary and sufficient for heterochromatin protein 1(HP1) binding. They bind nuclear receptors and Kruppel-associated boxes (KRAB) specifically and respectively. 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).

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 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.

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 5 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 fifth PHD finger.

Bromodomain, brd7_like subgroup. The BRD7 gene encodes a nuclear protein that has been shown to inhibit cell growth and the progression of the cell cycle by regulating cell-cycle genes at the transcriptional level. BRD7 has been identified as a gene involved in nasopharyngeal carcinoma. The protein interacts with acetylated histone H3 via its bromodomain. Bromodomains are 110 amino acid long domains that are found in many chromatin associated proteins. Bromodomains can interact specifically with acetylated lysine.
