Gt(pU21)96Imeg, or N-6 adenine-specific DNA methyltransferase 2 (putative), is a human gene encoded by N6AMT2. The encoded protein is an enzyme with an amino acid length of 214 and a mass of 24.5 kDa. Other isoforms may exist. Gt(pU21)96Imeg is a member of the Class I-like SAM-binding methyltransferase superfamily, EFM5 family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
