Measurement of histone mRNA transcript abundance in Xenopus oocytes by a quantitative primer extension assay.

abstract：:There are five methyl binding domain (MBD) proteins characterized by a methyl CpG-binding domain. Four MBD proteins (MeCP2 and MBDs 1-3) are linked to transcriptional repression and one (MBD4), to DNA repair. During preimplantation development, the embryo undergoes global demethylation following fertilization and sele...
