RNA G-quadruplexes (RG4) occur in vivo and have regulatory roles in mRNA metabolism. Here the authors show that the guanine residue stretches at the 5’ end of tRNA-derived stress-induced RNAs mediate the formation of tetramolecular RG4 structures, which play a role in the post-transcriptional regulation of gene expression.
