Coagulation Factor V Proteins and Enzymes

The F5 gene encodes a 2,224 amino acid long, 251 kDA coagulation factor V protein that is critical in the regulation of homeostasis. Additionally, F5 functions as a cofactor for the prothrombinase activity of factor Xa which results in the initiation of prothrombin to thrombin. F5 participates in blood coagulation signaling pathways, the blood clotting cascade, platelet degranulation as well as activation, signaling, and aggregation, and in responses to elevated platelet cytosolic Ca2+.
