  • a fraction of VCP is localized to the early endosome membrane, where it binds EEA1 via the N-terminal C2H2 zinc finger domain

  • basic FUNCTION
  • homohexameric AAA (ATPase associated with a variety of activities)
  • vesicular transport and fusion
  • involved in the transfer of membranes from the endoplasmic reticulum to the golgi apparatus occurs via 50-70 nm transition vesicles which derive from part-rough, part-smooth transitional elements of the endoplasmic reticulum
  • 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
  • participating in a number of cellular processes including endoplasmic reticulum-associated degradation (ERAD)
  • multiubiquitin chain-targeting factor in the degradation of the ubiquitin-proteasome pathway
  • binding to an ubiquitylated form of Aurora B on chromatin, resulting in extraction of Aurora B from chromatin, allowing chromosome decondensation and nuclear envelope formation
  • essential biochemical component of a wide range of ubiquitin-linked cell biological reactions, including ubiquitin-proteasome system-mediated protein degradation, Golgi and endoplasmic reticulum (ER) membrane fusion, transcription factor activation, and DNA repair
  • having functions in endocytic trafficking by establishing EEA1 as a new VCP substrate
