Factor VIII also known as anti-hemophilic factor is a glycoprotein with a molecular mass of approximately 250 kDa. This protein circulates in the plasma mainly in the liver where hepatocytes produce it. Factor VIII remains inactive while circulating in the blood and exists within the factor VIII/von Willebrand factor complex. Upon activation it plays a significant role in the blood coagulation process.
Biological function summary
Factor VIII greatly contributes to hemostasis by serving as a cofactor for factor IXa forming the intrinsic tenase complex. This activation results in the conversion of factor X to factor Xa which is important for the common pathway of the coagulation cascade. By participating in the clotting process factor VIII ensures proper wound healing and prevention of blood loss.
Pathways
Factor VIII activity is pivotal within the coagulation cascade particularly the intrinsic and common pathways. Activation of the intrinsic pathway begins through interactions with factor IXa leading to efficient activation of factor X. This process closely relates factor VIII to proteins like factor IX and factor X ensuring proper clot formation and stabilization. Factor VIII products and assays are available to study and characterize its critical role in these pathways.
Factor VIII is closely associated with hemophilia A a genetic bleeding disorder resulting from deficiency or dysfunction of this protein. Patients with hemophilia A exhibit prolonged bleeding times due to impaired coagulation. The disorder links directly to von Willebrand factor as it protects factor VIII from degradation in circulation stabilizing its presence in the blood. Anti-factor VIII antibodies are important tools for diagnosing and studying factor VIII-related disorders.
