Description
This gene encodes a preproprotein that is proteolytically processed to generate two protein products, megakaryocyte potentiating factor and mesothelin. Megakaryocyte potentiating factor functions as a cytokine that can stimulate colony formation of bone marrow megakaryocytes. Mesothelin is a glycosylphosphatidylinositol-anchored cell-surface protein that may function as a cell adhesion protein. This protein is overexpressed in epithelial mesotheliomas, ovarian cancers and in specific squamous cell carcinomas. Alternative splicing results in multiple transcript variants, at least one of which encodes an isoform that is proteolytically processed.
Bio-activity
Measured by its binding ability in a functional ELISA. When Recombinant Mouse Mesothelin C-Terminal (aa 298-600) His-tag (Catalog 8604-MS) is immobilized at 2 μg/mL (100 μL/well), the concentration of Recombinant Human CA125/MUC16 that produces 50% optimal binding response is approximately 0.4-2.4 ng/mL.
