Biochem/physiol Actions

Factor Vaserves as a receptor and positive effector offactorXa. Hence it can efficiently help in the conversion of prothrombin to thrombin.

Factor V is a key component in blood coagulation systems, where deficiencies can inhibit thrombin generation and affect hemostasis. It has been used in studies of coagulopathic bleeding which occurs following injury and is a leading cause of hospital deaths.

General description

Factor V, a glycoprotein is usually seen in the alpha granules of platelets and in plasma.

Factor Va is the activated form of factor V and the cofactor of Xa. It is a component of the prothrombinase complex.
