The AAA(+) ATPase valosin containing protein (VCP) is crucial for maintaining the stability of cells and organs, especially in the nervous system. VCP collaborates with various cofactors to ensure proteostasis and is linked to human health through numerous mutations. Dysfunctional VCP is associated with neurodegeneration and other diseases, as it is responsible for dismantling protein aggregates and removing dysfunctional organelles. Further research is needed to uncover the molecular mechanisms connecting VCP mutations to specific brain pathologies and explore its potential as a drug target for neurodegeneration.
The AAA(+) ATPase valosin containing protein (VCP) is essential for cell and organ homeostasis, especially in cells of the nervous system. As part of a large network, VCP collaborates with many cofactors to ensure proteostasis under normal, stress, and disease conditions. A large number of mutations have revealed the importance of VCP for human health. In particular, VCP facilitates the dismantling of protein aggregates and the removal of dysfunctional organelles. These are critical events to prevent malfunction of the brain and other parts of the nervous system. In line with this idea, VCP mutants are linked to the onset and progression of neurodegeneration and other diseases. The intricate molecular mechanisms that connect VCP mutations to distinct brain pathologies continue to be uncovered. Emerging evidence supports the model that VCP controls cellular functions on multiple levels and in a cell type specific fashion. Accordingly, VCP mutants derail cellular homeostasis through several mechanisms that can instigate disease. Our review focuses on the association between VCP malfunction and neurodegeneration. We discuss the latest insights in the field, emphasize open questions, and speculate on the potential of VCP as a drug target for some of the most devastating forms of neurodegeneration.
