Epigenetic memory meets G2/M: to remember or to forget?

摘要

The histone H3 lysine 27 (H3K27) methyltransferase EZH2 is essential for stem cell maintenance and proliferation. Recent insights suggest that the cyclin-dependent kinase CDK1 phosphorylates EZH2 at specific threonine residues by sensing developmental cues to mediate self-renewal or differentiation during G2/M phase.
