Elongator complex protein 1

UniProtKB accession:  Q06706

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Component of the elongator complex which is required for multiple tRNA modifications, including mcm5U (5-methoxycarbonylmethyl uridine), mcm5s2U (5-methoxycarbonylmethyl-2-thiouridine), and ncm5U (5-carbamoylmethyl uridine) (PubMed:15769872, PubMed:18755837, PubMed:31309145, PubMed:25569479). The elongator complex catalyzes formation of carboxymethyluridine in the wobble base at position 34 in tRNAs (PubMed:29332244). Functions as a gamma-toxin target (TOT); disruption of the complex confers resistance to Kluyveromyces lactis toxin zymocin (pGKL1 killer toxin) (PubMed:12424236). May also be involved in sensitivity to Pichia inositovora toxin (PubMed:13680368). ELP1/IKI3 binds to tRNA, mediating interaction of the elongator complex with tRNA (PubMed:24750273). Independently, may be involved in polarized exocytosis (PubMed:15780940).
