DNMT3A

DNMT3A

A gene on chromosome 2p23 that encodes a DNA methyltransferase thought to function in de novo methylation, rather than maintenance methylation. The protein localises to the cytoplasm and nucleus; its expression is developmentally regulated.

Although these enzymes place in the same category of enzymes and have second catalytic characteristics but may have different role in tumor development: DNMT3A deletion can stimulate and grow the tumor (Gao, 2011) in the other hand, DNMT3B deletion can stop tumor creation through the deployment and activation of tumor suppressor genes have got silent earlier (Nosho, 2009; Linhart, 2007).
