WebDnmt3A, Dnmt3B, and Dnmt3L (see Fig. 1) (20, 21). Dnmt3A and -3B have a regulatory N-terminal domain that in contrast to Dnmt1 is not essential for catalysis (22, 23) but is involved in enzyme targeting (24–27). The N-terminal parts of Dnmt3A and -3B contain an ATRX-like Cys-rich domain (also called PHD domain) and a PWWP domain, which are ... WebNov 1, 2024 · The de novo DNA methyltransferases Dnmt3a and Dnmt3b play crucial roles in developmental and cellular processes. Their enzymatic activities are stimulated by a regulatory protein Dnmt3L (Dnmt3-like) in vitro. However, genetic evidence indicates that Dnmt3L functions predominantly as a regulator of Dnmt3a in germ cells.
