Function in SwissProt
Component of the RNA polymerase II elongator complex, a multiprotein complex associated with the RNA polymerase II (Pol II) holoenzyme, and which is involved in transcriptional elongation (PubMed:10024884, PubMed:11296232, PubMed:11689709, PubMed:11904415). The elongator complex 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). The elongator complex catalyzes formation of carboxymethyluridine in the wobble base at position 34 in tRNAs (PubMed:29332244). It 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. May be involved in tRNA modification (PubMed:13680368). Independently, ELP3 may be involved in polarized exocytosis (PubMed:15780940).
