在这一期的展望中,Owens和Liu讨论了Flamand等人在本期《基因与发展》上的一篇论文,他们开发了一种新的方法(Tribe-Stamp),该方法可以检测单个mRNA分子上两个不同的限制性商业惯例的结合事件,他们首先将这种方法应用于YTHDF家族的N6-甲基腺苷(M6A)阅读器蛋白。RNA结合蛋白(RBPs)在RNA代谢和基因调控中起重要作用。在本期《基因与发育》杂志上,Flamand及其同事(pp.1002-1015)开发了一种新方法(Tribe-Stamp),该方法可以检测单个mRNA分子上两个不同的限制性商业惯例的结合事件,他们首先将这种方法应用于N6-甲基腺苷(M6A)阅读器蛋白的YTHDF家族。研究人员表明,这些限制性商业惯例在很大程度上共享一个公共的结合转录本池,并且单个mRNA在其整个生命周期中可能被多个YTHDF蛋白结合。这种单分子技术是研究不同限制性商业惯例之间潜在的协同和/或拮抗作用的一种令人兴奋的新方法。
In this Outlook, Owens and Liu discuss a paper in this issue of Genes & Development from Flamand et al., who developed a new method (TRIBE-STAMP) that detects binding events by two distinct RBPs on single mRNA molecules, which they first applied to the YTHDF family of N6-methyladenosine (m6A) reader proteins. RNA binding proteins (RBPs) are important players in RNA metabolism and gene regulation. In this issue of Genes & Development, Flamand and colleagues (pp. 1002–1015) developed a new method (TRIBE-STAMP) that detects binding events by two distinct RBPs on single mRNA molecules, which they first applied to the YTHDF family of N6-methyladenosine (m6A) reader proteins. The investigators show that these RBPs largely share a common pool of bound transcripts and that an individual mRNA may be bound by multiple YTHDF proteins throughout its lifetime. This single-molecule technique is an exciting new method to study potential synergy and/or antagonism between different RBPs.
