Description:
The F2 gene encodes coagulation factor II (also called prothrombin), an essential component in the early stages of the blood coagulation cascade. It is synthesized in the liver as an inactive precursor. It is proteolytically cleaved to form the active enzyme thrombin (serine protease) by the prothrombinase complex, which consists of factor Xa, factor Va and Ca2+ assembled on an anionic phospholipid membrane. Complete activation of thrombin requires cleavage at two sites, Arg320 and Arg271. Thrombin plays an important role in haemostasis and thrombosis; it converts fibrinogen to fibrin for blood clot formation, stimulates platelet aggregation, and activates coagulation factors V, VIII, and XIII. Furthermore, thrombin interacts with thrombomodulin to activate protein C (natural anticoagulant mechanism). The activated protein C inactivates coagulation cofactors, factors Va and VIIIa, dampening thrombin formation and in turn inhibiting acute inflammation triggered by coagulation. Mutations in F2 lead to various forms of thrombosis and dysprothrombinemia. Although evidence is conflicting, studies conducted among Brazilian sickle cell disease (SCD) patients revealed a non-significant association between F2 gene variants and vascular complications (e.g., thrombosis, stroke, and avascular necrosis) of SCD.
