Ribosome stalling results in the production of truncated proteins that can cause proteotoxic stress if not efficiently degraded. A recent paper by Izawa et al. (2017) identifies Vms1 as a key player in the regulation of ribosome quality control specifically on mitochondria-localized ribosomes, ultimately preventing protein aggregate accumulation within mitochondria.
