几乎所有的动物和植物都利用小RNA分子来控制不同发育阶段和病毒感染时的蛋白质表达。结构和机制研究已经开始阐明这些途径的三个基本方面:小RNA生物合成,RNA诱导沉默复合物(RISC)的形成和互补mRNA的靶向。在这里,我们回顾了令人兴奋的最新进展,了解调控RNA是如何产生的,以及它们是如何在RNA干扰(RNAi)过程中触发mRNA的特异性破坏的。
Virtually all animals and plants utilize small RNA molecules to control protein expression during different developmental stages and in response to viral infection. Structural and mechanistic studies have begun to illuminate three fundamental aspects of these pathways: small RNA biogenesis, formation of RNA-induced silencing complexes (RISCs) and targeting of complementary mRNAs. Here we review exciting recent progress in understanding how regulatory RNAs are produced and how they trigger specific destruction of mRNAs during RNA interference (RNAi).
