tRNA(Thr) (cytosine(32)-N(3))-methyltransferase

UniProtKB accession:  Q08641

Grouped By:  Matching UniProtKB accession

UniProtKB description:  S-adenosyl-L-methionine-dependent methyltransferase that mediates N(3)-methylcytidine modification of residue 32 of the tRNA anticodon loop of tRNA(Thr) and tRNA(Ser) (PubMed:21518804, PubMed:21518805, PubMed:28003514). N(3)-methylcytidine methylation of tRNA(Thr) requires the N6-threonylcarbamoylation of tRNA (t6A37) by the EKC/KEOPS complex as prerequisite (PubMed:28003514). N(3)-methylcytidine methylation of tRNA(Ser) requires the formation of N(6)-dimethylallyladenosine(37) (i6A37) by MOD5 as prerequisite (PubMed:28003514). Methylation of tRNA(Ser) is also stimulated by SES1 (PubMed:28003514). Binds F-actin and shows weak F-actin cross-linking activity (PubMed:9467951).
