Background:
Catalyzes the methylation of 5-carboxymethyl uridine to 5-methylcarboxymethyl uridine at the wobble position of the anticodon loop in tRNA via its methyltransferase domain. Catalyzes the last step in the formation of 5-methylcarboxymethyl uridine at the wobble position of the anticodon loop in target tRNA. Has a preference for tRNA(Arg and tRNA(Glu, and does not bind tRNA(Lys(PubMed:20308323. Binds tRNA and catalyzes the iron and alpha-ketoglutarate dependent hydroxylation of 5-methylcarboxymethyl uridine at the wobble position of the anticodon loop in tRNA via its dioxygenase domain, giving rise to 5-(S-methoxycarbonylhydroxymethyluridine; has a preference for tRNA(Gly. Required for normal survival after DNA damage. May inhibit apoptosis and promote cell survival and angiogenesis.
