ProQ/FinO‐domain proteins: another ubiquitous family of RNA matchmakers?

What is it about?

Small regulatory RNAs modulate almost all aspects of bacterial physiology. Many of these small RNAs require a chaperone protein for function. The chaperone protein characterized most extensively thus far is Hfq, but recent studies discussed in this review have revealed that proteins with a FinO domain constitute a second major class of bacterial chaperones.
