  • Function
    Factor Xa is a vitamin K-dependent glycoprotein that converts prothrombin to thrombin in the presence of factor Va, calcium and phospholipid during blood clotting.
  • Tissue specificity
    Plasma; synthesized in the liver.
  • Involvement in disease
    Defects in F10 are the cause of factor X deficiency (FA10D) [MIM:227600]. A hemorrhagic disease with variable presentation. Affected individuals can manifest prolonged nasal and mucosal hemorrhage, menorrhagia, hematuria, and occasionally hemarthrosis. Some patients do not have clinical bleeding diathesis.
  • Sequence similarities
    Belongs to the peptidase S1 family.
    Contains 2 EGF-like domains.
    Contains 1 Gla (gamma-carboxy-glutamate) domain.
    Contains 1 peptidase S1 domain.
  • Post-translational
    modifications
    The vitamin K-dependent, enzymatic carboxylation of some glutamate residues allows the modified protein to bind calcium.
    N- and O-glycosylated.
    The activation peptide is cleaved by factor IXa (in the intrinsic pathway), or by factor VIIa (in the extrinsic pathway).
    The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate and asparagine is (R) stereospecific within EGF domains.
  • Cellular localization
    Secreted.
  • Information by UniProt
