Transitional endoplasmic reticulum ATPase (TER ATPase) also known as valosin-containing protein (VCP) is an enzyme that in humans is encoded by the VCP gene.[1][2][3]

Function[edit]

Valosin-containing protein (VCP) is a type II member of AAA+-ATPase family. It functions as a ubiquitin segregase that remodels multimeric protein complexes by extracting polyubiquitinated proteins for recycling or degradation by the proteasome. VCP subserves a broad array of cellular functions including that includes mitochondrial quality control, autophagy, vesicle transport and fusion, 26S proteasome function, and assembly of peroxisomes. VCP, as a structural protein, is associated with clathrin, and heat-shock protein Hsc70, to form a complex. VCP has been implicated in a number of cellular events that are regulated during mitosis, including homotypic membrane fusion, spindle pole body function, and ubiquitin-dependent protein degradation.[3]

Interactions[edit]

Valosin-containing protein has been shown to interact with AMFR,[4][5] SELS,[6][7] BRCA1,[8] NSFL1C,[9] IκBα[10] and Ataxin 3.[7][11]

Clinical significance[edit]

Mutations in VCP are causative of a pleiotropic degenerative disorder called multisystem proteinopathy or "MSP" that can affect muscle, bone and/or the central nervous system. MSP can manifest clinically as classical amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), inclusion body myopathy (IBM), Paget's disease of bone (PDB), or as a combination of these disorders.[12][13]
