特徴

• Primordial germ cell (PGCs)-specific protein involved in epigenetic chromatin reprogramming in the zygote following fertilization.
• In zygotes, DNA demethylation occurs selectively in the paternal pronucleus before the first cell division, while the adjacent maternal pronucleus and certain paternally-imprinted loci are protected from this process.
• Participates in protection of DNA methylation in the maternal pronucleus by preventing conversion of 5mC to 5hmC: specifically recognizes and binds histone H3 dimethylated at 'Lys-9' (H3K9me2) on maternal genome, and protects maternal genome from TET3-mediated conversion to 5hmC and subsequent DNA demethylation.
• Does not bind paternal chromatin, which is mainly packed into protamine and does not contain much H3K9me2 mark.
• Also protects imprinted loci that are marked with H3K9me2 in mature sperm from DNA demethylation in early embryogenesis.
• May be important for the totipotent/pluripotent states continuing through preimplantation development.
• Also involved in chromatin condensation in oocytogenesis (By similarity).
• Applications:Suitable for use in Western Blot.
• Other applications not tested.
