The protein encoded by this gene is an RNA cytidine acetyltransferase involved in histone acetylation, tRNA acetylation, the biosynthesis of 18S rRNA, and the enhancement of nuclear architecture and chromatin organization. [provided by RefSeq, Oct 2016]
RNA cytidine acetyltransferase with specificity toward both 18S rRNA and tRNAs (PubMed:25411247, PubMed:25653167). Catalyzes the formation of N(4)-acetylcytidine (ac4C) at position 1842 in 18S rRNA (PubMed:25411247). May also catalyze the formation of ac4C at position 1337 in 18S rRNA (By similarity). Required for early nucleolar cleavages of precursor rRNA at sites A0, A1 and A2 during 18S rRNA synthesis (PubMed:25411247, PubMed:25653167). Catalyzes the formation of ac4C in serine and leucine tRNAs (By similarity). Requires the tRNA-binding adapter protein THUMBD1 for full tRNA acetyltransferase activity but not for 18S rRNA acetylation (PubMed:25653167). Can acetylate both histones and microtubules (PubMed:14592445, PubMed:17631499, PubMed:19303003). Histone acetylation may regulate transcription and mitotic chromosome de-condensation (PubMed:17631499). Activates telomerase activity by stimulating the transcription of TERT, and may also regulate telomerase function by affecting the balance of telomerase subunit assembly, disassembly, and localization (PubMed:14592445, PubMed:18082603). Acetylates alpha-tubulin, which may affect microtubule stability and cell division (PubMed:19303003).
