Abstract The ATP-driven chaperone valosin-containing protein (VCP)/p97 governs critical steps in ubiquitin-dependent protein quality control and intracellular signalling pathways. It cooperates with diverse partner proteins to help process ubiquitin-labelled proteins for recycling or degradation by the proteasome in many cellular contexts. Recent studies have uncovered unexpected cellular functions for p97 in autophagy, endosomal sorting and regulating protein degradation at the outer mitochondrial membrane, and elucidated a role for p97 in key chromatin-associated processes. These findings extend the functional relevance of p97 to lysosomal degradation and reveal a surprising dual role in protecting cells from protein stress and ensuring genome stability during proliferation.
