Methyltransferase Like Protein 7B (METTL7B)

METTL7B belongs to the methyltransferase superfamily. It is a probable methyltransferase. A methyltransferase is a type of transferase enzyme that transfers a methyl group from a donor to an acceptor. Methylation often occurs on nucleic bases in DNA or amino acids in protein structures.

Methytransferases use a reactive methyl group bound to sulfur in S-adenosyl methionine (SAM) as the methyl donor. DNA methylation is often utilized to silence and regulate genes without changing the original DNA sequence, an example of epigenetic modification. This methylation occurs on cytosine residues. DNA methylation may be necessary for normal growth from embryonic stages in mammals.
