  • FunctionCentral regulator of hemostasis. It serves as a critical cofactor for the prothrombinase activity of factor Xa that results in the activation of prothrombin to thrombin.
  • Tissue specificityPlasma.
  • Involvement in diseaseFactor V deficiency
    Thrombophilia due to activated protein C resistance
    Budd-Chiari syndrome
    Ischemic stroke
    Pregnancy loss, recurrent, 1
  • Sequence similaritiesBelongs to the multicopper oxidase family.
    Contains 3 F5/8 type A domains.
    Contains 2 F5/8 type C domains.
    Contains 6 plastocyanin-like domains.
  • DomainDomain B contains 35 x 9 AA tandem repeats, and 2 x 17 AA repeats.
  • Post-translational
    Thrombin activates factor V proteolytically to the active cofactor, factor Va (formation of a heavy chain at the N-terminus and a light chain at the C-terminus).
    Sulfation is required for efficient thrombin cleavage and activation and for full procoagulant activity.
    Activated protein C inactivates factor V and factor Va by proteolytic degradation.
    Phosphorylation sites are present in the extracellular medium.
