特徴

• Methylation at the 5'-position of cytosine is the only known naturally occurring covalent modification of the mammalian genome.
• DNA methylation requires the enzymatic activity of DNA 5-cytosine methyltransferase (Dnmt) proteins, which catalyze the transfer of a methyl group from S-adenosyl methionine to the 5'-position of cytosines residing in the dinucleotide CpG motif, and this methylation results in transcriptional repression of the target gene.
• The Dnmt enzymes are encoded by independent genes.
• Dnmt1 is the most abundant, and it preferentially methylates hemimethylated DNA and coordinates gene expression during development.
• Additional mammalian Dnmt proteins include Dnmt2 and Dnmt3.
• Dnmt2 lacks the large N-terminal regulator domain of Dnmt1, is expressed at substantially lower levels in adult tissues, and is likely involved in methylating newly integrated retroviral DNA.
• Dnmt3a and Dnmt3b are encoded by two distinct genes, but both are abundantly expressed in embryonic stem cells, where they also methylate CpG motifs on DNA.
