![]() | ![]() Title: Molecular Basis of VCPIP1 and P97/VCP Interaction Reveals Its Functions in Post-Mitotic Golgi Reassembly. Authors: Tianzhui Liao / Ruotong Li / Ping Lu / Yusong Liu / Rong Yang / Hao Guo / Zhuoxi Wu / Ruiwen Wang / Ling Yuan / Zhengmao Hu / Haishan Gao / Faxiang Li / ![]() Abstract: The VCPIP1-P97/VCP (Valosin-Containing Protein) complex is required for post-mitotic Golgi cisternae reassembly and maintenance in interphase. However, the organization and mechanism of this complex ...The VCPIP1-P97/VCP (Valosin-Containing Protein) complex is required for post-mitotic Golgi cisternae reassembly and maintenance in interphase. However, the organization and mechanism of this complex in regulating Golgi membrane fusion is still elusive. Here, the cryo-electron microscopy (cryo-EM) structures of the human VCPIP1-P97/VCP complex are presented. These studies reveal that three independent VCPIP1 molecules sit over the C-terminal substrate exit tunnel formed by P97/VCP homo-hexamer, resulting in an unusual C3 to C6 symmetric barrel architecture. The UFD1 (unknown function domain 1) from VCPIP1, but not the N-terminal OTU domain and the C-terminal UBL domain, docks to the two adjacent D2 domains of P97/VCP, allosterically causing the cofactors binding domain-NTDs (N-terminal domains) of P97/VCP in a "UP" and D1 domain in an ATPase competent conformation. Conversely, VCPIP1 bound P97/VCP hexamer favors the binding of P47, and thus the intact SNARE complex, promoting Golgi membrane fusion. These studies not only reveal the unexpected organization of humanVCPIP1-P97/VCP complex, but also provide new insights into the mechanism of VCPIP1-P97/VCP mediated Golgi apparatus reassembly, which is a fundamental cellular event for protein and lipid processing. | |||||||||||||||||||||||||||||||||||||||
