tRNA (cytidine(32)/guanosine(34)-2'-O)-methyltransferase

UniProtKB accession:  P38238

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Methylates the 2'-O-ribose of nucleotides at positions 32 and 34 of the tRNA anticodon loop of substrate tRNAs (PubMed:11927565, PubMed:22912484, PubMed:26310293, PubMed:31586407). Requisite for faithful cytoplasmic translation (By similarity). Requires TRM732 for methylation of the cytidine at position 32 of the anticodon loop of substrate tRNAs (PubMed:22912484). Requires RTT10/TRM734 for methylation of the nucleotide at position 34 of the anticodon loop of substrate tRNAs (PubMed:22912484). May modify position 32 in tRNA(Leu(UAA)), tRNA(Phe(GAA)), and tRNA(Trp(CCA)) and position 34 in tRNA(Leu(UAA)), tRNA(Phe(GAA)) and tRNA(Trp(CCA)) (PubMed:22912484). Methylation of tRNA(Phe) at position 34 plays a role in the oxidative stress-response as it may promote translation of UUC over UUU, and UUC-containing genes are enriched for oxidative stress-responsive processes (PubMed:32053677).
