These processes can depend on protein extraction and unfolding by the essential mechanoenzyme valosin-containing protein (VCP) and on ubiquitin chain remodeling by ubiquitin-specific proteases known as deubiquitinases (DUBs). How the activities of VCP and DUBs are coordinated is poorly understood. Here, we focus on the DUB VCPIP1, a VCP interactor required for post-mitotic Golgi and ER organization. We determine ∼3.3 Å cryogenic electron microscopy structures of VCP-VCPIP1 complexes in the absence of added nucleotide or the presence of an ATP analog. We find that up to 3 VCPIP1 protomers interact with the VCP hexamer to position VCPIP1's catalytic domain at the exit of VCP's central pore, poised to cleave ubiquitin following substrate unfolding. We observe competition between VCPIP1 and other cofactors for VCP binding and show that VCP stimulates VCPIP1's DUB activity. Together, our data suggest how the two enzyme activities can be coordinated to regulate proteostasis. 履歴 登録 2025年1月2日 - ヘッダ(付随情報) 公開 2025年3月26日 - マップ公開 2025年3月26日 - 更新 2025年5月21日 - 現状 2025年5月21日 処理サイト : RCSB / 状態 : 公開
