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.

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].
