TRMT61A encodes the human gene, TRNA methyltransferase 61A. It may also be known as: tRNA(m1A58)-methyltransferase subunit TRMT61A; tRNA(m1A58)MTase subunit TRMT61A; C14orf172; GCD14; Gcd14p; TRM61; hTRM61. The encoded protein is an enzyme with an amino acid length of 289 and a mass of 31.4 kDa. Other isoforms may exist. TRMT61A is a member of the Class I-like SAM-binding methyltransferase superfamily, TRM61 family. Homologs of this gene exist in other organisms, including: Mouse, Rat.
