title: A BLAST from the past: ancient origin of human Sm proteins.
abstract: In this issue of Molecular Cell, Zhang et al. and Møller et al. independently report studies of the E. coli Hfq protein, revealing significant sequence similarities with human Sm proteins. Their findings suggest that Hfq, and the Sm and Sm-like (Lsm) proteins, may function in stabilizing interactions between RNA molecules.
