Target

  • Function

    Required for normal vault structure. Vaults are multi-subunit structures that may act as scaffolds for proteins involved in signal transduction. Vaults may also play a role in nucleo-cytoplasmic transport. Down-regulates INFG-mediated STAT1 signaling and subsequent activation of JAK. Down-regulates SRC activity and signaling through MAP kinases.
  • Tissue specificity

    Present in most normal tissues. Higher expression observed in epithelial cells with secretory and excretory functions, as well as in cells chronically exposed to xenobiotics, such as bronchial cells and cells lining the intestine. Overexpressed in many multidrug-resistant cancer cells.
  • Sequence similarities

    Contains 9 MVP (vault) repeats.
  • Domain

    MVP 3 mediates interaction with PTEN.
    MVP 4 mediates interaction with PARP4.
  • Post-translational
    modifications

    Phosphorylated on Tyr residues after EGF stimulation.
    Dephosphorylated by PTPN11.
  • Cellular localization

    Cytoplasm. Nucleus > nuclear pore complex. 5% found in the nuclear pore complex. Translocates from the nucleus to the cytoplasm upon EGF treatment.
