DNA (cytosine-5)-methyltransferase 3A is an enzyme that in humans is encoded by the DNMT3A gene.

CpG methylation is an epigenetic modification that is important for embryonic development, imprinting, and X-chromosome inactivation. Studies in mice have demonstrated that DNA methylation is required for mammalian development. This gene encodes a DNA methyltransferase that is thought to function in de novo methylation, rather than the maintenance of existing methylated sites. The protein localizes to the cytoplasm and nucleus and its expression is developmentally regulated. Alternative splicing results in multiple transcript variants encoding different isoforms.

Interactions

DNMT3A has been shown to interact with ZNF238, HDAC1, Myc, Protein inhibitor of activated STAT2, DNMT1, DNMT3B, PIAS1, UBE2I and SUV39H1.
