Abstract excerpt
Epigenetic inheritance of DNA methylation in mammals requires a multifunctional protein UHRF1, which is believed to recruit DNMT1 to DNA replication forks through a unique hemi-methylated CpG-binding activity. Here we demonstrate that the UHRF1 mutants deficient in binding either hemi-methylated CpG or H3K9me2/3, but not both, are able to associate with pericentric heterochromatin, recruit Dnmt1 and partially...
