INTRODUCTION Abstract INTRODUCTION Results DISCUSSION METHODS AND MATERIALS SUPPLEMENTARY MATERIALS Funding Author contributions Competing interests Data and materials availability Supplemental Figures REFERENCES DNA methylation, as a major epigenetic modification in the genome of higher eukaryotes, is catalyzed by DNA methyltransferase enzymes (DNMTs) by addition of a methyl group to the 5th carbon position of cytosine, resulting 5-methylcytosine (5mC) (1, 2). DNMT1 is the most abundant DNA methyltransferase in mammalian cells, and mainly methylate hemi-methylated CpG dinucleotides as a maintenance methyltransferase, although DNMT1 has also been ...
