Messenger RNAs (mRNAs) that induce stalling during translation are degraded by a quality control mechanism known as no-go decay (NGD). The aberrant mRNAs are recognized by two factors, Dom34 and Hbs1. Using cryo-EM to visualize NGD intermediates bound to a stalled ribosome, Beckman and coworkers suggest how binding of Dom34-Hbs1 may lead to ribosome disassembly and recruitment of mRNA degradation factors.
