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 B1 is leukocyte elastase inhibitor. Ser B3 is squamos cell carcinoma antigen 1. Ser B5 is Maspin. Ser I1 is neuroserpin. Ser A10 is protein Z-related protease inhibitor. Ser A1 is alpha-1 antitrypsin. Ser A3 is α 1-antichymotrypsin. Ser E1 is plasminogen activator inhibitor 1. 3D structures of serpin Updated on 25-May-2025 Ser 1mtp, 1sng – Ser – Thermobifida fusca Ser A1 Alpha-1-antitrypsin Ser A3 (α 1-antichymotrypsin) 2ach, 1as4, 3caa – hSer-A3 4caa, 1qmn, 3dlw – hSer-A3 (mutant) 1yxa – Ser-A3N - mouse Ser A5 2ol2 – hSer-A5 3dy0 – hSer-A5 + heparin Ser A6 Corticosteroid-binding globulin Ser A7 2riv – hSer-A7 2riw – hSer-A7 + thyroxine 2xn3 – hSer-A7 + mefenamic acid 2xn5 – hSer-A7 + furosemide 2xn6, 2xn7 – hSer-A7 + thyroxine-fluoresein Ser A8 2jp8 – hSer-A8 – NMR 2wxw – hSer-A8 2x0b – hSer-A8 + renin 2wxx, 2wxy, 2wy0 – Ser-A8 – mouse 2wxz, 2wy1 – rSer-A8 Ser A10 3h5c, 3f1s – hSer-A10 + vitamin K-dependent protein Z Ser A12 4if8 – hSer-A12 Ser B1 (leukocyte elastase inhibitor) 1hle – Ser-B1 – horse 4ga7 – hSer-B1 (mutant) Ser B3 2zv6 – hSer-B3 Ser B5 (Maspin) 1xqg, 1wz9, 1xu8 - hSer-B5 1xqj – hSer-B5 (mutant) Ser C1 Antithrombin Ser E1 Plasminogen activator inhibitor Ser E2 4dy0 – hSer-E2 + heparin Ser-I1 3fgq, 2f02, 3f5n – hSer-I1 Ser K 1sek – ThSer-K – Tobacco hornworm Ser 1 1k9o – ThSer-1 (mutant) + trypsin II 3le2 – Ser-1 – Arabidopsis thaliana Ser 2 1m93 – Ser-2 – Cowpox virus 3nda – Ser-2 – Sheep tick 3pzf – Ser-2 – malaria mosquito
