Factors inhibited by protein c and protein s
Protein S is partly homologous to other vitamin K-dependent plasma coagulation proteins, such as protein C and factors VII, IX, and X. Similar to them, it has a Gla domain and several EGF-like domains (four rather than two), but no serine protease domain. Instead, there is a large C-terminus domain that is homologous to plasma steroid hormone-binding proteins such as sex hormone-binding globulin and corticosteroid-binding globulin. It may play a role in the protein functions as … WebApr 11, 2024 · Inhibiting protein synthesis is believed to help reduce inflammation by interfering with the production of certain proteins that are involved in the inflammatory response. This can help to improve symptoms and allow people with Crohn’s to better manage their condition.
