This Week in Cell

A group of Princeton University and Caltech researchers write in Cell that small RNAs are involved in quorum-sensing pathways. The researchers found that the small RNA Qrr3 relies on four different mechanisms to influence its targets. For instance, it uses catalytic degradation to repress luxR, while using coupled degradation and sequestration to repress luxM and luxO, respectively. And it activates aphA by revealing the ribosome-binding site.
