Serpin

Serpin or serine protease inhibitor (Ser) are protease inhibitors. Ser E1 is antithrombin. Ser C1 is antithrombin . Ser A5 is protein C inhibitor. Ser A6 is a cortisol-binding globulin. Ser A8 is angiotensinogen. Ser A7 is a thyroxine-binding globulin. Ser B3 is squamos cell carcinoma antigen 1. Ser I1 is neuroserpin. Ser A10 is protein Z-related protease inhibitor. Ser A1 is alpha-1 antitrypsin. Ser E1 is plasminogen activator inhibitor 1.
