Gamma carboxylation of clotting factors
Gamma-glutamyl carboxylase is an enzyme that catalyzes the posttranslational modification of vitamin K-dependent proteins. Many of these vitamin K-dependent proteins are involved in coagulation so the function of the encoded enzyme is essential for hemostasis. Most gla domain-containing proteins depend on this carboxylation reaction for posttranslational modification. In humans, the gamma-glutamyl carboxylase enzyme is most highly expressed in the liver. WebDescription: Homo sapiens protein S (alpha) (PROS1), mRNA. RefSeq Summary (NM_000313): This gene encodes a vitamin K-dependent plasma protein that functions as a cofactor for the anticoagulant protease, activated protein C (APC) to inhibit blood coagulation. It is found in plasma in both a free, functionally active form and also in an …
