CATEGORY

enzyme

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytosolic
	intracellular,nucleus,nucleoplasm

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
