A small RNA guides a post-transcriptional regulatory protein to its target

RNA-binding proteins are central to post-transcriptional regulation and are generally thought to recognize their target RNAs through direct binding. Here, we uncover a previously unrecognized mechanism in which a small RNA (sRNA) guides a protein regulator to specific target mRNAs, enabling programmable post-transcriptional control. By mapping in pathogenic Escherichia coli the RNA interactome of…
