Abstract:

A large number of epigenetic chemical modifications have been detected in cellular mRNA and non-coding RNAs. Among these modifications, N4-acetylcytidine(ac4C) is a relatively unique one, which has widely been discovered in tRNA, rRNA and tRNAs in eukaryotes and prokaryotes. Current research have shown that ac4C RNA may possess a variety of biological functions, including regulating the translation process of proteins, affecting the stability of RNA, and modulating RNA-protein interactions. However, only one ac4C acetyltransferase, NAT10, has been identified so far. Besides, current technical methods for the detection and sequencing of ac4C RNA are quite limited. This review comprehensively summarized current advances in the exploration of distribution of ac4C RNA, its roles in gene expression regulation and its detection methods. Finally the opportunities and shortcomings of the related research on ac4C were summarized and prospected.

Key words: N4-Acetylcytidine, RNA modification, Detection method
