Such motifs are among the most common tertiary interactions in known RNA structures, comparable in number with the non-canonical base pairs. They are …
WebMar 13, 2006 · Posttranscriptional regulation of gene expression plays important roles in diverse cellular processes. This regulation is often mediated by specific RNA-binding proteins (RBPs) that bind to elements in the UTRs of mRNAs and regulate the stability, translation, or localization of the mRNA (1–3).Whereas many classical studies explored … WebApr 1, 2015 · Here we survey known examples of global RNA symmetry, including the true quaternary symmetry of the bacteriophage ϕ29 prohead RNA (pRNA) and the internal …
