Role of Tet proteins in 5mC to 5hmC conversion, ES-cell self-renewal and inner cell mass specification
DNA methylation is one of the best-characterized epigenetic modifications. Although the enzymes that catalyse DNA methylation have been characterized, enzymes responsible for demethylation have been elusive. A recent study indicates that the human TET1 protein could catalyse the conversion of 5-methylcytosine (5mC) of DNA to 5-hydroxymethylcytosine (5hmC), raising the possibility that DNA …
