    basic FUNCTION
  • methyltransferase activity
  • required for tRNA 7-methylguanosine-methyltransferase activity (Alexandrov 2002)
  • catalyses the 7-methylguanosine modification of tRNA (Cartlidge 2005)
  • NSUN2 and METTL1, are required for protecting tRNA against tRNA decay (RTD)
  • METTL1 promotes cell proliferation and migration in hepatocellular carcinoma (HCC, and exerts oncogenic activities via suppression of PTEN signaling
