Molecular Basis of VCPIP1 and P97/VCP Interaction Reveals Its Functions in Post-Mitotic Golgi Reassembly.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

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 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.
