Vitamin K-dependent liver-produced serine protease
The product, is a plasma-derived human blood coagulation factor. Coagulation Factor X is a vitamin K-dependent, liver-produced serine protease that serves as the first enzyme in the coagulation cascade to form fibrin. It is a two-chain glycoprotein with the molecular weight of approximately 59 kDa. While Factor X normally circulates in the plasma as inactive molecules, the activation of Factor X is involved in both the intrinsic and extrinsic coagulation pathways.
