• Product name
    Anti-MVP antibody [1032]
    See all MVP primary antibodies
  • Description
    Mouse monoclonal [1032] to MVP
  • Host species
  • Specificity
    This antibody reacts with a 104 to 110 kD protein known as Major Vault Protein (MVP).
  • Tested applications
    Suitable for: WB, IP, IHC-P, IHC-Frmore details
  • Species reactivity
    Reacts with: Rat, Human
  • Immunogen

    Proteins precipitated with AER317 from the phosphocellulose column flow through of extract of human breast cancer MCF-7 cells.

  • Positive control
    • Breast.
  • General notes

    MVP is identical to Lung-Resistance Related Protein (LRP). Treatment of cells with estradiol increases the amount of MVP in nuclear extract. Antibodies to progesterone and glucocorticoid receptors are also able to co-immunoprecipitate the MVP.

  • 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
    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.
