翻译调控在正常生理状态和疾病状态中都起着重要的作用。这种调节需要主要位于5′和3′ UTR的顺式调节元件和反式调节因子(例如,RNA结合蛋白(RBP)识别特定的RNA特征并与翻译机制相互作用以调节其活性。在本文中,我们讨论了重要方面的5′ UTR介导的调控,提供了一个概述的特点和功能的主要元素,在这个区域,如uORF(上游开放阅读框架),二级结构,和RBP结合基序和不同的翻译调控机制,以及它们对基因表达和人类健康的影响时,解除管制。
Translation regulation plays important roles in both normal physiological conditions and diseases states. This regulation requires cis-regulatory elements located mostly in 5′ and 3′ UTRs and trans-regulatory factors (e.g., RNA binding proteins (RBPs)) which recognize specific RNA features and interact with the translation machinery to modulate its activity. In this paper, we discuss important aspects of 5′ UTR-mediated regulation by providing an overview of the characteristics and the function of the main elements present in this region, like uORF (upstream open reading frame), secondary structures, and RBPs binding motifs and different mechanisms of translation regulation and the impact they have on gene expression and human health when deregulated.
