Where this comes from

Abstract

Chen et al. demonstrate a new way by which noncoding RNAs tailor the function of multicomponent complexes. They show that a noncoding RNA interacts with an exoribonuclease, altering its substrate specificity and enzymatic activity by serving as a ribonucleoprotein scaffold and, perhaps, a gate for entry of the RNA substrate.
