VCP/p97 is an AAA+ ATPase that, together with its cofactors UFD1-NPL4 (p97-UN), unfolds ubiquitylated substrates to maintain cellular homeostasis. The human p97-UN complex associates with additional cofactors, but how these cofactors modulate p97-UN activity is not fully understood. Here, we screen cofactors and identi...

Haem-Regulated Inhibitor (HRI, aka EIF2AK1) is one of four stress-sensing kinases that phosphorylate eIF2α as part of the integrated stress response (ISR). HRI was first characterized as a haem-sensing kinase where it is inhibited when bound to haem. Recent studies have revealed another role for HRI in sensing mitochon...

A non-canonical proteolytic function of USP5 is revealed, uncovering a previously unrecognised regulatory axis linking deubiquitinating enzymes to protein maturation, expanding the substrate repertoire for USP5 and providing a framework for identifying protease–substrate relationships in post-translational regulation.
