title: Physiology of tmRNA: what gets tagged and why?
abstract: Transfer-messenger RNA (tmRNA) enters stalled translational complexes and, with small protein B (SmpB), mediates peptide tagging of the nascent protein and release of the stalled ribosome. Recent studies clarify how the tmRNA system is targeted to ribosomes and suggest that tmRNA-tagging is used for both quality control and specific regulation of cellular physiology.
