Abstract:

The 3′ untranslated regions (3′UTRs) are a component of eukaryotic messenger RNAs (mRNAs) and located at their 3′-most ends. 3′UTRs play crucial roles in post-transcriptional regulation of gene expression, regulating cleavage and polyadenylation, mRNA stability, mRNA translation and localization. With deepening research of the 3′UTRs, and with advent of various omics methods, a few unexpected functions of the eukaryotic 3′UTRs have been uncovered. In this review, we summarize recent advances in the study of 3′UTRs and propose the future research directions for studying the roles and mechanisms of the 3′UTRs, with the aim to provide a better reference for comprehensively investigating gene function and regulation.

Key words: gene, 3′ untranslated region (3′UTR), post-transcritional regulation, isolated 3′UTR (i3′UTR), protein multifunctionality
