We report the first genome-wide landscape of H3K9me2 ChIP-seq profile in mouse oocytes. We also performed whole-genome bisulfite sequencing and RNA-seq analysis of G9a conditional KO oocytes and maternal KO preimplantation embryos. Our findings illuminate the functional importance of G9a in preimplantation development and, in addition, pose a question on the proposed role for H3K9me2 in protection of the maternal genome from active CG demethylation.

How this grade was computed

The insufficient grade is a transparent weighted average. Each metric below scored from 0–100% against the published ChIP-seq thresholds, weighted by its importance; nothing is hidden or subjective.
