Abstract
In zygotes, a global loss of DNA methylation occurs selectively in the paternal pronucleus before the first cell division, concomitantly with the appearance of modified forms of 5-methylcytosine. The adjacent maternal pronucleus and certain paternally-imprinted loci are protected from this process. Nakamura et al. recently clarified the molecular mechanism involved: PGC7/Stella/Dppa3 binds to dimethylated histone 3 lysine 9 (H3K9me2), thereby blocking the activity of the Tet3 methylcytosine oxidase in the maternal genome as well as at certain imprinted loci in the paternal genome.Entities:
