WebDNMT1 is crucial for mammalian development, proliferation and survival of cancer cells (6-9). It attaches a methyl group to the carbon-5 (C5) position of cytosine residues using AdoMet as a cofactor. With an unmethylated DNA substrate, the full-length DNMT1 is catalytically poor compared to its activity on the same hemimethylated DNA sequence (10). WebDNMT1 (DNA (Cytosine-5-)-Methyltransferase 1) proteins are involved in DNA methylation in which a methyl group is added to a cytosine residue on DNA, commonly at the C5 position of a CpG dinucleotide. Three families …
