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; 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.

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.

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.

first PWWP domain found in nuclear receptor-binding SET domain-containing (NSD) proteins; The nuclear receptor binding SET domain (NSD) protein family consists of three HMTases, NSD1, NSD2/MMSET/WHSC1, and NSD3/WHSC1L1 that are critical in maintaining the chromatin integrity. Reducing NSD activity through specific lysine-HMTase inhibitors appears promising in suppressing cancer growth. NSD proteins have specific mono- and dimethylase activities for H3K36, and play nonredundant 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, through 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 (C5HCH). This model corresponds to the first PWWP domain. This family also includes Drosophila melanogaster maternal-effect sterile 4 (dMes4) that may act as a histone-lysine N-methyltransferase required for wing morphogenesis. The PWWP domain specifically recognizes DNA and histone methylated lysines.

PWWP domain found in Arabidopsis thaliana histone-lysine N-methyltransferase trithorax-like proteins ATX1, ATX2, and similar proteins; This family includes A. thaliana ATX1 and ATX2, which are sister paralogs originating from a segmental chromosomal duplication. They are plant counterparts of the Drosophila melanogaster trithorax (TRX) and mammalian mixed-lineage leukemia (MLL1) proteins. ATX1, also called protein SET domain group 27, or trithorax-homolog protein 1 (TRX-homolog protein 1), is a methyltransferase that trimethylates histone H3 at lysine 4 (H3K4me3). It also acts as a histone modifier and as a positive effector of gene expression. ATX1 regulates transcription from diverse classes of genes implicated in biotic and abiotic stress responses. It is involved in dehydration stress signaling in both abscisic acid (ABA)-dependent and ABA-independent pathways. ATX2, also called protein SET domain group 30, or trithorax-homolog protein 2 (TRX-homolog protein 2), is involved in dimethylating histone H3 at lysine 4 (H3K4me2). Both ATX1 and ATX2 are multi-domain containing proteins that consist of an N-terminal PWWP domain, FYRN- and FYRC (DAST, domain associated with SET in trithorax) domains, a canonical plant homeodomain (PHD) domain, a non-canonical extended PHD (ePHD) domain, and a C-terminal SET domain. The PWWP domain specifically recognizes DNA and histone methylated lysines.
