tRNA-derived RNAs: Biogenesis and roles in translational control

Transfer RNA (tRNA)-derived RNAs (tDRs) are a class of small non-coding RNAs that play important roles in different aspects of gene expression. These ubiquitous and heterogenous RNAs, which vary across different species and cell types, are proposed to regulate various biological processes. In this review, we will discuss aspects of their biogenesis, and specifically, their contribution into translational control. We will summarize diverse roles of tDRs and the molecular mechanisms underlying their functions in the regulation of protein synthesis and their impact on related events such as stress-induced translational reprogramming.This article is categorized under:RNA Processing > Processing of Small RNAsRegulatory RNAs/RNAi/Riboswitches > Regulatory RNAsRegulatory RNAs/RNAi/Riboswitches > Biogenesis of Effector Small RNAs
