Prothrombin Antibody (Thrombin)

F2 (Coagulation Factor II), also known as prothrombin and thrombin, is a serine protease that in humans is encoded by the F2 gene. The activated thrombin enzyme plays an important role in hemostasis and thrombosis: it converts fibrinogen to fibrin for blood clot formation, stimulates platelet aggregation, and activates coagulation factors V, VIII(F8), and XIII(F13A1). Thrombin also inhibits coagulation by Activating protein C.
