ADDz domain found in DNA (cytosine-5) methyltransferases (C5-MTases) 3a (Dnmt3a); Dnmt3a is a member of the Dnmt3 family and is a protein with de novo DNA methyltransferase activity. Dnmt3 family members are Dnmt3a, Dnmt3b, and Dnmt3l the non-enzymatic regulatory factor. Dnmt3a is recruited by Dnmt3l to unmethylated histone H3 and methylates the target. Dnmt3a has a variable region at the N-terminus, followed by a conserved PWWP region and the cysteine-rich ADDz domain. ADDz_Dnmt3a is an active catalytic domain of Dnmt3a. DNA methylation is an important epigenetic mechanism involved in diverse biological processes such as embryonic development, gene expression, and genomic imprinting. The methyltransferase activity of Dnmt3a is not only responsible for the establishment of DNA methylation pattern, but is also essential for the inheritance of these patterns during mitosis. The ADDz_Dnmt3 domain 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. A knockout of Dnmt3a has been shown to be lethal in the mouse model.

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.

DNMT3A, also called DNA methyltransferase HsaIIIA, DNA MTase HsaIIIA, or M.HsaIIIA, modifies DNA in a non-processive manner and also methylates non-CpG sites. It may preferentially methylate DNA linker between 2 nucleosomal cores and is inhibited by histone H1. DNMT3A is recruited to trimethylated 'Lys-36' of histone H3 (H3K36me3) sites. DNMT3B, also called DNA methyltransferase HsaIIIB, DNA MTase HsaIIIB, or M.HsaIIIB, 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. Members of this family contains a PWWP domain that is responsible for establishing DNA methylation patterns during embryogenesis and gametogenesis.

PWWP domain found in methyl-CpG-binding domain protein 5 (MBD5) and similar proteins; MBD5, is a methyl-CpG-binding protein that binds to heterochromatin. It does not interact with either methylated or unmethylated DNA. MBD5 acts as a transcriptional regulator responsible for 2q23.1 deletion syndrome. It belongs to the MBD family proteins, which play central roles in transcriptional regulation and development. The PWWP domain specifically recognizes DNA and histone methylated lysines.

Cytosine-C5 specific DNA methylases; Methyl transfer reactions play an important role in many aspects of biology. Cytosine-specific DNA methylases are found both in prokaryotes and eukaryotes. DNA methylation, or the covalent addition of a methyl group to cytosine within the context of the CpG dinucleotide, has profound effects on the mammalian genome. These effects include transcriptional repression via inhibition of transcription factor binding or the recruitment of methyl-binding proteins and their associated chromatin remodeling factors, X chromosome inactivation, imprinting and the suppression of parasitic DNA sequences. DNA methylation is also essential for proper embryonic development and is an important player in both DNA repair and genome stability.

PWWP domain found in PWWP domain-containing protein 2A (PWWP2A); PWWP2A is a H2A.Z-specific chromatin binding protein which may play an important role in the neural crest stem cell migration and differentiation during early development. It is also required for proper mitosis progression. PWWP2A and its paralog PWWP2B form a stable complex with NuRD subunits MTA1/2/3:HDAC1/2:RBBP4/7, but not with MBD2/3, p66alpha/beta, and CHD3/4. The PWWP domain specifically recognizes DNA and histone methylated lysines.

PWWP domain found in Arabidopsis thaliana histone-lysine N-methyltransferase trithorax-like protein ATX3, ATX4, ATX5, and similar proteins; The family includes A. thaliana ATX3 (also called protein SET domain group 14, or trithorax-homolog protein 3), ATX4 (also called protein SET domain group 16, or trithorax-homolog protein 4) and ATX5 (also called protein SET domain group 29, or trithorax-homolog protein 5), which belong to the histone-lysine methyltransferase family. They show distinct phylogenetic origins from the family of ATX1 and ATX2. They are multi-domain containing protein that consists of an N-terminal PWWP domain, 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.

PWWP domain found in hepatoma-derived growth factor (HDGF)-related protein (HRP) family; The HRP family includes hepatoma-derived growth factor (HDGF), and HDGF-related proteins (HRPs). HDGF, also called high mobility group protein 1-like 2 (HMG-1L2), is a heparin-binding protein that acts as a transcriptional repressor with mitogenic activity for fibroblasts. 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.

PWWP domain found in Saccharomyces cerevisiae ISWI one complex protein 4 (ScIOC4) and similar proteins; ScIOC4 functions as a component of the ISW1B complex, which acts in remodeling the chromatin by catalyzing an ATP-dependent alteration in the structure of nucleosomal DNA. The ISW1B complex acts within coding regions to control the amount of RNA polymerase II released into productive elongation and to coordinate elongation with termination and pre-mRNA processing. The family also includes Schizosaccharomyces pombe PWWP domain-containing proteins 1 and 2 (SpPDP1 and SpPDP2). SpPDP1 associates with Set9 to regulate its chromatin localization and methyltransferase activity towards H4K20. Members of this family contain a PWWP domain. The PWWP domain specifically recognizes DNA and histone methylated lysines.
