DNA (cytosine-5)-methyltransferase 3A (DNMT3A) is a methyltransferase involving in methyl group transference. The epigenetic modification is important for embryonic development, imprinting, and X-chromosome inactivation. DNMT3A has been shown to interact with protein like HDAC1 (1), Myc (2), Protein inhibitor of activated STAT2 (3) etc.
