摘要

Ribosome-associated quality control (RQC) safeguards translation by detecting and resolving collided ribosomes and triaging their nascent chains. This Review outlines mechanisms, crosstalk and disease implications of RQC cascades and presents RQC as a ‘first responder’ that prevents escalation to global stress responses and provides protection against proteostasis collapse.
