General annotation (Comments)
| Function | Membrane-anchored forms may play a role in cellular adhesion. Ref.9 Ref.11 Megakaryocyte-potentiating factor (MPF) potentiates megakaryocyte colony formation in vitro. Ref.9 Ref.11 |
| Subunit structure | Interacts with MUC16. Ref.11 |
| Subcellular location | Cell membrane; Lipid-anchor › GPI-anchor. Golgi apparatus Ref.2 Ref.13. |
| 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). Ref.1 Ref.12 |
| Post-translational modification | Both MPF and the cleaved form of mesothelin are N-glycosylated. Ref.2 Ref.9 Ref.12 Proteolytically cleaved by a furin-like convertase to generate megakaryocyte-potentiating factor (MPF), and the cleaved form of mesothelin. Ref.2 |
| Involvement in disease | Note=Antibodies against MSLN are detected in patients with mesothelioma and ovarian cancer. Ref.4 |
| Sequence similarities | Belongs to the mesothelin family. |
