  1. prothrombin

    Thrombin (EC, fibrinogenase, thrombase, thrombofort, topical, thrombin-C, tropostasin, activated blood-coagulation factor II, blood-coagulation factor IIa, factor IIa, E thrombin, beta-thrombin, gamma-thrombin) is a serine protease, an enzyme that, in humans, is encoded by the F2 gene. Prothrombin (coagulation factor II) is proteolytically cleaved to form thrombin in the clotting process. Thrombin in turn acts as a serine protease that converts soluble fibrinogen into insoluble strands of fibrin, as well as catalyzing many other coagulation-related reactions.


  1. prothrombin

    Prothrombin, also known as factor II, is a protein present in blood plasma that is involved in the blood clotting process. It is produced by the liver and is converted into thrombin, which is a key enzyme in the process of coagulation, leading to the formation of a blood clot. The conversion is dependent on the presence of prothrombin activators, such as activated Factor V and Factor X, as well as calcium ions. The level of prothrombin in the body can be measured to diagnose bleeding disorders or to monitor the effectiveness of anticoagulant treatment.

U.S. National Library of Medicine

  1. Prothrombin

    A plasma protein that is the inactive precursor of thrombin. It is converted to thrombin by a prothrombin activator complex consisting of factor Xa, factor V, phospholipid, and calcium ions. Deficiency of prothrombin leads to hypoprothrombinemia.
