DESCRIPTION

Also known as ELP3_HUMAN, ELP3. Catalytic tRNA acetyltransferase subunit of the RNA polymerase II elongator complex, which is a component of the RNA polymerase II (Pol II) holoenzyme and is involved in transcriptional elongation (PubMed:11714725, PubMed:11818576, PubMed:15902492, PubMed:16713582). 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:29415125). In the elongator complex, acts as a tRNA uridine(34) acetyltransferase by mediating formation of carboxymethyluridine in the wobble base at position 34 in tRNAs (By similarity). May also act as a protein lysine acetyltransferase by mediating acetylation of target proteins; such activity is however unclear in vivo and recent evidences suggest that ELP3 primarily acts as a tRNA acetyltransferase (PubMed:29415125). Involved in neurogenesis: regulates the migration and branching of projection neurons in the developing cerebral cortex, through a process depending on alpha-tubulin acetylation (PubMed:19185337). Required for acetylation of GJA1 in the developing cerebral cortex (By similarity). Component of the RNA polymerase II elongator complex (Elongator), which consists of ELP1, STIP1/ELP2, ELP3, ELP4, ELP5 and ELP6. ELP1, STIP1/ELP2 and ELP3 form the Elongator core complex (PubMed:11714725, PubMed:11818576, PubMed:22854966). Elongator associates with the C-terminal domain (CTD) of Pol II largest subunit (PubMed:11714725, PubMed:11818576, PubMed:22854966). Interacts with ELP1 (PubMed:11818576, PubMed:19185337). Interacts with alpha-tubulin (PubMed:19185337).
