Anti-Thrombomodulin Antibody, clone 411-201B clone 411-201B, from rat

Thrombomodulin (UniProt P15306; also known as CD141, Fetomodulin, SnoRNA MBII-339, TM) is encoded by the Thbd gene (Gene ID 21824) in murine species. Thrombomodulin (TM) is an endothelial cell surface protein that functions to suppress the propagation of thrombin (activated blood-coagulation factor II) generation by acting as a thrombin receptor. Formation of the TM-thrombin complex abolishes thrombin's procoagulant activity by altering its substrate specificity, leading to proteolytic cleavage of protein C into the natural anticoagulant termed "activated protein C". Together with protein S, activated protein C proteolytically cleaves activated coagulation factors Va and VIIIa, thereby preventing the generation of activated coagulation factors Xa and thrombin. Murine thrombomodulin is initially produced with an N-terminal propeptide (a.a. 1-16) sequence, the removal of which yields the mature protein with a large extracellular region (a.a. 17-517), a transmembrane segment (a.a. 518-541), and a short cytoplamic tail (a.a. 542-577).
