Function Of Factor Ix

Factor IX circulates in plasma as an inactive zymogen that is activated during coagulation to factor IXa—a vitamin K-dependent serine protease. Activation results from cleavage of factor IX by either factor XIa or factor VIIa/tissue factor in the presence of Ca2+. Factor IXa then forms a complex with factor VIIIa on the cell membrane surface which is responsible for the activation of factor X. This forms part of the series of reactions constituting the blood coagulation cascade that ultimately leads to the formation of a fibrin clot.[1]
