evolution | nonessential tRNA modifications by methyltransferases are evolutionarily conserved and have been reported to stabilize mature tRNA molecules and prevent rapid tRNA decay. The tRNA modifying enzymes, NSUN2 and METTL1, are mammalian orthologues of yeast Trm4 and Trm8, which are required for protecting tRNA against tRNA decay | Homo sapiens |
malfunction | combined knockdown of NSUN2, EC 2.1.1.203, and METTL1 in HeLa cells drastically potentiate sensitivity of cells to 5-fluorouracil, but does not affect cisplatin- and paclitaxel-induced cytotoxicity, synergistic effects of NSUN2 and METTL1 double knockdown, which causes rapid tRNA(ValAAC) degradation induced by destabilizing 5-fluorouracil | Homo sapiens |
physiological function | Nonessential tRNA modifications by methyltransferases are evolutionarily conserved and have been reported to stabilize mature tRNA molecules and prevent rapid tRNA decay. The tRNA modifying enzyme METTL1 is a mammalian orthologues of yeast Trm8, which is required for protecting tRNA against tRNA decay | Homo sapiens |
