From: The Dynamics and Regulatory Mechanism of Pronuclear H3k9me2 Asymmetry in Mouse Zygotes
Schematic figure showing possible mechanism of asymmetric H3K9me2 in fertilized eggs.
Certain unknown protein (?) prevents G9a from binding to H3k9 sites of the male pronucleus before 8 h of IVF. The unknown new born protein (UNBP) inhibits G9a catalysis after 10 h of IVF.
