m1A RNA Modification in Gene Expression Regulation

Abstract

N1-methyladenosine (m1A) is a prevalent and reversible post-transcriptional RNA modification that decorates tRNA, rRNA and mRNA. Recent studies based on technical advances in analytical chemistry and high-throughput sequencing methods have revealed the crucial roles of m1A RNA modification in gene regulation and biological processes. In this review, we focus on progress in the study of m1A methyltransferases, m1A demethylases and m1A-dependent RNA-binding proteins and highlight the biological mechanisms and functions of m1A RNA modification, as well as its association with human disease. We also summarize the current understanding of detection approaches for m1A RNA modification.
