DNMT3s are de novo DNA methyltransferases responsible for the establishment of DNA methylation patterns in mammalian genomes [1-4]. The ATRX-DNMT3-DNMT3L (ADD) domain contains two parts, a C2-C2-like zinc finger (Pfam:PF17980) and a PHD-like zinc finger, represented in this entry. In this domain, the conserved His residue observed in classical PHD zinc fingers is replaced by a cysteine.	Domain

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 c ...	The PWWP domain is named after a conserved Pro-Trp-Trp-Pro motif [1]. 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 catalyses 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 organising higher-order chromatin, maintaining genome stability, and regulating cell-cycle progression [2].

This is a C4-type GATA1-like zinc finger of a cysteine-rich domain termed ADD (ATRX-DNMT3-DNMT3L, AD-DATRX) found in animal DNMT3A proteins. The ADD domains of the DNMT3 family have a decisive role in blocking DNMT activity in the areas of the genome with chromatin containing methylated H3K4. This domain contains two parts, a GATA1-like and a PHD-like (Pfam:PF21255) zinc fingers. The DNA methyltransferase (DNMT) 3 family members DNMT3A and the DNMT3-like non-enzymatic regulatory factor DNMT3L, are involved in de-novo establishment of DNA methylation patterns in early mammalian development [1,2].
