5'-UTR RNA G-quadruplexes: translation regulation and targeting

RNA structures in the untranslated regions (UTRs) of mRNAs influence post-transcriptional regulation of gene expression. Much of the knowledge in this area depends on canonical double-stranded RNA elements. There has been considerable recent advancement of our understanding of guanine(G)-rich nucleic acids sequences that form four-stranded structures, called G-quadruplexes. While much of the research has been focused on DNA G-quadruplexes, there has recently been a rapid emergence of interest in RNA G-quadruplexes, particularly in the 5'-UTRs of mRNAs. Collectively, these studies suggest that RNA G-quadruplexes exist in the 5'-UTRs of many genes, including genes of clinical interest, and that such structural…
