Western blot analysis of Mesothelin on different lysates. Proteins were transferred to a PVDF membrane and blocked with 5% BSA in PBS for 1 hour at room temperature. The primary antibody was used at a 1:500 dilution in 5% BSA at room temperature for 2 hours. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1:5,000 dilution was used for 1 hour at room temperature.<br /> Positive control: <br /> Lane 1: SiHa cell lysate<br /> Lane 2: Hela cell lysate

  • Immunohistochemical analysis of paraffin-embedded human tonsil tissue using anti-Mesothelin antibody. The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 8.0-8.4) for 20 minutes. The tissues were blocked in 5% BSA for 30 minutes at room temperature, washed with ddH2O and PBS, and then probed with the antibody (ER1803-76) at 1/100 dilution, for 30 minutes at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chrogen. Counter stained with hematoxylin and mounted with DPX.

SEQUENCE SIMILARITIES

Belongs to the mesothelin family.

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).

POST-TRANSLATIONAL MODIFICATION

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.

SUBCELLULAR LOCATION

Cell membrane, Golgi apparatus, Membrane, Secreted.

FUNCTION

This gene encodes a preproprotein that is proteolytically processed to generate two protein products, megakaryocyte potentiating factor and mesothelin. Mesothelin is a glycosylphosphatidylinositol-anchored cell-surface protein that may function as a cell adhesion protein. Alternative splicing results in multiple transcript variants, at least one of which encodes an isoform that is proteolytically processed. Mesothelin is over expressed in several human tumors, including mesothelioma, ovarian cancer, pancreatic adenocarcinoma and cholangiocarcinoma. The interaction between mesothelin and MUC16 (also known as CA125) may facilitate the implantation and peritoneal spread of tumors by cell adhesion. Dr. Mitchell Ho and colleagues at the National Cancer Institute identified the region (residues 296-359) consisting of 64 amino acids at the N-terminus of cell surface mesothelin as the functional binding domain for MUC16.
