RNA分子往往通过分子内RNA-RNA相互作用(RRI)形成复杂的三级结构,以调节转录、RNA加工和翻译过程。在这些生物过程中,RNA,特别是非编码RNA,通常通过分子间RNA-RNA碱基配对来实现其调控特异性,并通过相关的RNA结合蛋白来执行其调控结果。解码分子内和分子间的RRIs是了解各种RNA分子的结构及其在发育、分化和疾病中的调节作用的先决条件。最近发明了许多基于测序的方法,并揭示了哺乳动物细胞中异常复杂的RRI。在这里,我们讨论了为研究细胞RRIs而开发的各种方法的技术进步和局限性,重点是RRIs在基因调控中的新兴架构角色。
RNA molecules tend to form intricate tertiary structures via intramolecular RNA–RNA interactions (RRIs) to regulate transcription, RNA processing, and translation processes. In these biological processes, RNAs, especially noncoding RNAs, usually achieve their regulatory specificity through intermolecular RNA–RNA base pairing and execute their regulatory outcomes via associated RNA-binding proteins. Decoding intramolecular and intermolecular RRIs is a prerequisite for understanding the architecture of various RNA molecules and their regulatory roles in development, differentiation, and disease. Many sequencing-based methods have recently been invented and have revealed extraordinarily complicated RRIs in mammalian cells. Here, we discuss the technical advances and limitations of various methodologies developed for studying cellular RRIs, with a focus on the emerging architectural roles of RRIs in gene regulation.
