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.

PWWP domain found in protein BS69, protein kinase C-binding protein 1 (PRKCBP1) 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. BS69 is a multi-domain protein, containing bromo, plant homeodomain (PHD), proline-tryptophan-tryptophan-proline (PWWP), and MYeloid translocation protein 8, Nervy and DEAF-1 (MYND) domains. The specific role of the PWWP domain within BS69 is not clearly identified, but BS69 functions in chromatin remodeling, consistent with other PWWP-containing 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 PHD finger, a bromodomain, and a PWWP domain. The PWWP domain specifically recognizes DNA and histone methylated lysines.

PWWP (Pro-Trp-Trp-Pro) domain; The PWWP domain, named for a conserved Pro-Trp-Trp-Pro motif, is a small domain consisting of 100-150 amino acids and is composed of a five-stranded antiparallel beta-barrel followed by a helical region. It is found in numerous proteins that are involved in cell division, growth, and differentiation. Most PWWP-domain proteins seem to be nuclear, often DNA-binding, proteins that function as transcription factors regulating a variety of developmental processes. PWWP domains specifically recognize DNA and histone methylated lysines at the level of the nucleosome. Based on the fact that other regions of PWWP-domain proteins are responsible for nuclear localization and DNA-binding, is likely that the PWWP domain acts as a site for protein-protein binding interactions, influencing chromatin remodeling and thereby regulating transcriptional processes. Some PWWP-domain proteins have been linked to cancer or other diseases; some are known to function as growth factors.

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.

It is a prognostic factor in several types of cancer. HDGFL1 is also called PWWP domain-containing protein 1 (PWWP1). Its biological function remains unclear. HDGFL2, also called HDGF-related protein 2 (HRP-2), or hepatoma-derived growth factor 2 (HDGF-2), is involved in cellular growth control, through the regulation of cyclin D1 expression. HDGFL3, also called HDGF-related protein 3 (HRP-3), enhances DNA synthesis and may play a role in cell proliferation. The family also includes PC4 and SFRS1-interacting protein (PSIP) and similar proteins. PSIP, also called CLL-associated antigen KW-7, dense fine speckles 70 kDa protein (DFS 70), lens epithelium-derived growth factor (LEDGF), or transcriptional coactivator p75/p52, acts as a transcriptional coactivator involved in neuroepithelial stem cell differentiation and neurogenesis. Members of the HRP family contains a PWWP domain, which is necessary for DNA binding.

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.

Bromodomain, polybromo repeat I. Polybromo is a nuclear protein of unknown function, which contains 6 bromodomains. The human ortholog BAF180 is part of a SWI/SNF chromatin-remodeling complex, and it may carry out the functions of Yeast Rsc-1 and Rsc-2. It was shown that polybromo bromodomains bind to histone H3 at specific acetyl-lysine positions. Bromodomains are found in many chromatin-associated proteins and in nuclear histone acetyltransferases. They interact specifically with acetylated lysine, but not all the bromodomains in polybromo may bind to acetyl-lysine.

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.

ADDz domain found in ATRX (alpha-thalassemia/mental retardation, X-linked); ADDz_ATRX is a PHD-like zinc finger domain of ATRX, which belongs to the SNF2 family of chromatin remodeling proteins. ATRX is a large chromatin-associated nuclear protein with two domains, ADDz_ATRX at the N-terminus, followed by a C-terminal ATPase/helicase domain. The ADDz_ATRX domain recognizes a specific methylated histone, and this interaction is required for heterochromatin localization of the ATRX protein. Missense mutations in either of the two ATRX domains lead to the X-linked alpha-thalassemia and mental retardation syndrome; however the mutations in the ADDz_ATRX domain produce a more severe disease phenotype that may also relate to disturbing unknown functions or interaction sites of this domain. The ADDz domain is also present in chromatin-associated proteins cytosine-5-methyltransferase 3 (Dnmt3); it is a PHD-like zinc finger motif that contains two parts, a C2-C2 and a PHD-like zinc finger. PHD zinc finger domains have been identified in more than 40 proteins that are mainly involved in chromatin mediated transcriptional control; the classical PHD zinc finger has a C4-H-C3 motif that spans about 50-80 amino acids. In ADDz, the conserved histidine residue of the PHD finger is replaced by a cysteine, and an additional zinc finger C2-C2 like motif is located about twenty residues upstream of the C4-C-C3 motif.

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.

PWWP domain found in DNA (cytosine-5)-methyltransferase 3B (DNMT3B); DNMT3B, also called DNA methyltransferase HsaIIIB, DNA MTase HsaIIIB, or M.HsaIIIB, is required for genome-wide de novo methylation and is essential for the establishment of DNA methylation patterns during development. It may preferentially methylate nucleosomal DNA within the nucleosome core region. DNMT3B may function as a transcriptional co-repressor by associating with CBX4 and independently of DNA methylation. In tumorigenesis, DNA methylation by DNMT3B is known to play a role in the inactivation of tumor suppressor genes. In addition, a point mutation in the PWWP domain of DNMT3B has been identified in patients with ICF (immunodeficiency, centromeric instability, and facial anomalies) syndrome, a rare autosomal recessive disorder characterized by hypomethylation of classical satellite DNA.

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).
