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.

Also Known As:

Factor II; Blood Coagulation Factor II; Differentiation Reversal Factor; Factor II, Coagulation; Factor, Differentiation Reversal; II, Coagulation Factor; Coagulation Factor II; Blood-coagulation factor II
