Thrombomodulin / CD141 (EP175), RMab

Summary and Explanation

Thrombomodulin, also known as CD141, is an endothelial-specific type 1 membrane receptor that binds thrombin, resulting in the activation of protein C. This causes the degradation of clotting factors Va and VIIIa and reduces the amount of thrombin generated. Defect in Thrombomodulin is a cause of thromboembolic disease, also known as inherited thrombophilia.

Thrombomodulin antibody was initially identified in endothelial cells, but is also found in extra-vascular sites, such as synctiotrophoblasts in the placenta, epithelial tissues in the gingiva, in skin and in the synovial lining cells. In tumors, Thrombomodulin is expressed in vascular tumors and squamous cell carcinoma in a variety of tissues, including oral mucosa, esophagus, and skin. Thrombodulin antibody is a useful marker for detecting angiosarcoma, and can also be used to distinguish between mesothelioma (positive) from lung adenocarcinoma (negative).
