N6-甲基腺苷 (m6A) 是真核 RNA 上发现的一种高度普遍且动态的修饰。尽管几十年来一直未能理解这种表观转录组标记的真正调控潜力,但近年来我们对 m6A 的了解迅速扩大。该修饰现已在功能上与 mRNA 代谢的所有阶段相关,并被证明可以调节多种生物过程。此外,m6A 已在多种病毒编码的转录本上得到鉴定。调查 m6A 在病毒-宿主相互作用中的功能的研究强调了不同的作用,表明对病毒生命周期的广泛调控。因此,揭示 m6A 修饰的真正影响可能会彻底改变我们对控制病毒复制的调控机制的理解。本文是 Soller Matthias 博士和 Fray Rupert 博士编辑的特刊的一部分,题为:基因表达控制中的 mRNA 修饰。 m6A 甲基化在功能上与 mRNA 代谢的所有阶段相关,并调节多种生物过程。 m6A 甲基化标记了多种病毒的基因组 RNA 和 mRNA。 m6A 甲基化在调节许多病毒的复制中发挥着重要作用。
N6-methyladenosine (m6A) is a highly pervasive and dynamic modification found on eukaryotic RNA. Despite the failure to comprehend the true regulatory potential of this epitranscriptomic mark for decades, our knowledge of m6A has rapidly expanded in recent years. The modification has now been functionally linked to all stages of mRNA metabolism and demonstrated to regulate a variety of biological processes. Furthermore, m6A has been identified on transcripts encoded by a wide range of viruses. Studies to investigate m6A function in viral-host interactions have highlighted distinct roles indicating widespread regulatory control over viral life cycles. As a result, unveiling the true influence of m6A modification could revolutionise our comprehension of the regulatory mechanisms controlling viral replication. This article is part of a Special Issue entitled: mRNA modifications in gene expression control edited by Dr. Soller Matthias and Dr. Fray Rupert. m6A methylation is functionally linked to all stages of mRNA metabolism and regulates a variety of biological processes. m6A methylation marks both the genomic RNA and mRNAs of multiple viruses. m6A methylation plays a significant role in modulating the replication of many viruses.
