    see all
  • FunctionProtein C is a vitamin K-dependent serine protease that regulates blood coagulation by inactivating factors Va and VIIIa in the presence of calcium ions and phospholipids (PubMed:25618265). Exerts a protective effect on the endothelial cell barrier function (PubMed:25651845).
  • Tissue specificityPlasma; synthesized in the liver.
  • Involvement in diseaseThrombophilia due to protein C deficiency, autosomal dominant
    Thrombophilia due to protein C deficiency, autosomal recessive
  • Sequence similaritiesBelongs 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 Glu residues allows the modified protein to bind calcium.
    N- and O-glycosylated. Partial (70%) N-glycosylation of Asn-371 with an atypical N-X-C site produces a higher molecular weight form referred to as alpha. The lower molecular weight form, not N-glycosylated at Asn-371, is beta. O-glycosylated with core 1 or possibly core 8 glycans.
    The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate and asparagine is (R) stereospecific within EGF domains.
    May be phosphorylated on a Ser or Thr in a region (AA 25-30) of the propeptide.
  • Cellular localizationSecreted. Golgi apparatus. Endoplasmic reticulum.
  • Information by UniProt
