摘要

? 2019 Elsevier LtdDiverse chemical modifications have been identified in the transcriptome, leading to the emerging field of epitranscriptomics. In eukaryotic mRNA, the 5′ cap and 3′ poly(A) tail play important roles in regulation, and multiple internal modifications have also been revealed to participate in RNA metabolism. In this review, we focus on internal modifications in eukaryotic mRNA, including modifications to A/U/C/G bases and to ribose as well. We provide an overview of their biogenesis, high-throughput detection methods, biological functions, and regulatory mechanisms, with an emphasis on their reported reader proteins (RNA-binding proteins that specifically bind to modified RNA). We also briefly discuss the current problems in the investigation of mRNA modifications that need to be solved.
