  • Function

    Membrane-anchored forms may play a role in cellular adhesion.
    Megakaryocyte-potentiating factor (MPF) potentiates megakaryocyte colony formation in vitro.
  • Tissue specificity

    Expressed in lung. Expressed at low levels in heart, placenta and kidney. Expressed in mesothelial cells. Highly expressed in mesotheliomas, ovarian cancers, and some squamous cell carcinomas (at protein level).
  • Involvement in disease

    Note=Antibodies against MSLN are detected in patients with mesothelioma and ovarian cancer.
  • Sequence similarities

    Belongs to the mesothelin family.
  • Post-translational

    Both MPF and the cleaved form of mesothelin are N-glycosylated.
    Proteolytically cleaved by a furin-like convertase to generate megakaryocyte-potentiating factor (MPF), and the cleaved form of mesothelin.
  • Cellular localization

    Secreted and Cell membrane. Golgi apparatus.

  • Mesothelin was immunoprecipitated from 1 mg of NIH/3T3 (mouse embryo fibroblast cell line) whole cell lysate with ab187063 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab187063 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10000 dilution.

    Lane 1: NIH/3T3 whole cell lysate 10 µg (Input). 

    Lane 2: ab187063 IP in NIH/3T3 whole cell lysate (+). 

    Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab187063 in NIH/3T3 whole cell lysate (-).

    Blocking and dilution buffer and concentration: 5% NFDM/TBST.

    Exposure time: 3 minutes.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab187063).
