RNA modifications are prevalent among all the classes of RNA, regulate diverse biological processes, and have emerged as a key regulatory mechanism in post-transcriptional control of gene expression. They are subjected to precise spatial and temporal control and shown to be critical for the maintenance of normal development and physiology. For example, mA modification of mRNA affects stability, recruitment of RNA binding protein (RBP), translation, and splicing. The deposition of m6A on the RNA happens co-transcriptionally, allowing the tight coupling between the transcription and RNA modification machinery. The mA modification is affected by transcriptional dynamics, but recent insights also suggest that mA machinery impacts transcription and chromatin signature.
RNA 修饰普遍存在于各类 RNA 中,调控多种生物过程,并已成为基因表达转录后调控的关键机制。它们受到精确的时空控制,并且对于维持正常的发育和生理机能至关重要。例如,mRNA 的 mA 修饰影响稳定性、RNA 结合蛋白(RBP)的募集、翻译和剪接。RNA 上的 m6A 修饰是共转录发生的,允许转录和 RNA 修饰机制紧密偶联。mA 修饰受到转录动态的影响,但最近的研究也表明,mA 机制会影响转录和染色质特征。
