  • Target

    • Function

      Factor VIII, along with calcium and phospholipid, acts as a cofactor for factor IXa when it converts factor X to the activated form, factor Xa.
    • Involvement in disease

      Defects in F8 are the cause of hemophilia A (HEMA) [MIM:306700]. A disorder of blood coagulation characterized by a permanent tendency to hemorrhage. About 50% of patients have severe hemophilia resulting in frequent spontaneous bleeding into joints, muscles and internal organs. Less severe forms are characterized by bleeding after trauma or surgery. Note=Of particular interest for the understanding of the function of F8 is the category of CRM (cross-reacting material) positive patients (approximately 5%) that have considerable amount of F8 in their plasma (at least 30% of normal), but the protein is non-functional; i.e., the F8 activity is much less than the plasma protein level. CRM-reduced is another category of patients in which the F8C antigen and activity are reduced to approximately the same level. Most mutations are CRM negative, and probably affect the folding and stability of the protein.
    • Sequence similarities

      Belongs to the multicopper oxidase family.
      Contains 3 F5/8 type A domains.
      Contains 2 F5/8 type C domains.
      Contains 6 plastocyanin-like domains.
    • Domain

      Domain F5/8 type C 2 is responsible for phospholipid-binding and essential for factor VIII activity.
    • Post-translational
      modifications

      Sulfation on Tyr-1699 is essential for binding vWF.
