CC -!- FUNCTION: Protein C is a vitamin K-dependent serine protease that
CC regulates blood coagulation by inactivating factors Va and VIIIa in the
CC presence of calcium ions and phospholipids. Exerts a protective effect
CC on the endothelial cell barrier function.
CC {ECO:0000250|UniProtKB:P04070}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Degradation of blood coagulation factors Va and VIIIa.;
CC EC=3.4.21.69;
CC -!- SUBUNIT: Synthesized as a single chain precursor, which is cleaved into
CC a light chain and a heavy chain held together by a disulfide bond. The
CC enzyme is then activated by thrombin, which cleaves a tetradecapeptide
CC from the amino end of the heavy chain; this reaction, which occurs at
CC the surface of endothelial cells, is strongly promoted by
CC thrombomodulin.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P04070}. Golgi
CC apparatus {ECO:0000250|UniProtKB:P04070}. Endoplasmic reticulum
CC {ECO:0000250|UniProtKB:P04070}.
CC -!- TISSUE SPECIFICITY: Plasma; synthesized in the liver.
CC -!- PTM: The vitamin K-dependent, enzymatic carboxylation of some Glu
CC residues allows the modified protein to bind calcium.
CC -!- PTM: The iron and 2-oxoglutarate dependent 3-hydroxylation of aspartate
CC and asparagine is (R) stereospecific within EGF domains. {ECO:0000250}.
CC -!- MISCELLANEOUS: Calcium also binds, with stronger affinity to another
CC site, beyond the GLA domain. This GLA-independent binding site is
CC necessary for the recognition of the thrombin-thrombomodulin complex.
CC -!- SIMILARITY: Belongs to the peptidase S1 family. {ECO:0000255|PROSITE-
CC ProRule:PRU00274}.
