Disease

ANT3_HUMAN Defects in SERPINC1 are the cause of antithrombin III deficiency (AT3D) [MIM:613118. AT3D is an important risk factor for hereditary thrombophilia, a hemostatic disorder characterized by a tendency to recurrent thrombosis. AT3D is classified into 4 types. Type I: characterized by a 50% decrease in antigenic and functional levels. Type II: has defects affecting the thrombin-binding domain. Type III: alteration of the heparin-binding domain. Plasma AT-III antigen levels are normal in type II and III. Type IV: consists of miscellaneous group of unclassifiable mutations.^[1] [:]^[2] ^[3] ^[4] ^[5] ^[6] ^[7] ^[8] ^[9] ^[10] ^[11] ^[12] ^[13] ^[14] ^[15] ^[16] ^[17] ^[18] ^[19] ^[20] ^[21] ^[22] [:]^[23] ^[24] ^[25] ^[26] ^[27] ^[28] ^[29] ^[30] ^[31] ^[32] ^[33] ^[34] ^[35]

Function

ANT3_HUMAN Most important serine protease inhibitor in plasma that regulates the blood coagulation cascade. AT-III inhibits thrombin, matriptase-3/TMPRSS7, as well as factors IXa, Xa and XIa. Its inhibitory activity is greatly enhanced in the presence of heparin.^[36]

Publication Abstract from PubMed

Antithrombin, the principal physiological inhibitor of the blood coagulation proteinase thrombin, requires heparin as a cofactor. We report the crystal structure of the rate-determining encounter complex formed between antithrombin, anhydrothrombin and an optimal synthetic 16-mer oligosaccharide. The antithrombin reactive center loop projects from the serpin body and adopts a canonical conformation that makes extensive backbone and side chain contacts from P5 to P6' with thrombin's restrictive specificity pockets, including residues in the 60-loop. These contacts rationalize many earlier mutagenesis studies on thrombin specificity. The 16-mer oligosaccharide is just long enough to form the predicted bridge between the high-affinity pentasaccharide-binding site on antithrombin and the highly basic exosite 2 on thrombin, validating the design strategy for this synthetic heparin. The protein-protein and protein-oligosaccharide interactions together explain the basis for heparin activation of antithrombin as a thrombin inhibitor.

The ternary complex of antithrombin-anhydrothrombin-heparin reveals the basis of inhibitor specificity.,Dementiev A, Petitou M, Herbert JM, Gettins PG Nat Struct Mol Biol. 2004 Sep;11(9):863-7. Epub 2004 Aug 15. PMID:15311268^[37]

+== Disease ==
+[https://www.uniprot.org/uniprot/ANT3_HUMAN ANT3_HUMAN] Defects in SERPINC1 are the cause of antithrombin III deficiency (AT3D) [MIM:[https://omim.org/entry/613118 613118]. AT3D is an important risk factor for hereditary thrombophilia, a hemostatic disorder characterized by a tendency to recurrent thrombosis. AT3D is classified into 4 types. Type I: characterized by a 50% decrease in antigenic and functional levels. Type II: has defects affecting the thrombin-binding domain. Type III: alteration of the heparin-binding domain. Plasma AT-III antigen levels are normal in type II and III. Type IV: consists of miscellaneous group of unclassifiable mutations.<ref>PMID:7734359</ref> [:]<ref>PMID:3191114</ref> <ref>PMID:9031473</ref> <ref>PMID:6582486</ref> <ref>PMID:3080419</ref> <ref>PMID:3805013</ref> <ref>PMID:3179438</ref> <ref>PMID:3162733</ref> <ref>PMID:2781509</ref> <ref>PMID:2365065</ref> <ref>PMID:2229057</ref> <ref>PMID:2013320</ref> <ref>PMID:1906811</ref> <ref>PMID:1555650</ref> <ref>PMID:1547341</ref> <ref>PMID:8443391</ref> <ref>PMID:8486379</ref> <ref>PMID:7981186</ref> <ref>PMID:7959685</ref> <ref>PMID:8274732</ref> <ref>PMID:7994035</ref> <ref>PMID:7989582</ref> [:]<ref>PMID:7878627</ref> <ref>PMID:7832187</ref> <ref>PMID:9157604</ref> <ref>PMID:9845533</ref> <ref>PMID:9759613</ref> <ref>PMID:10997988</ref> <ref>PMID:11794707</ref> <ref>PMID:11713457</ref> <ref>PMID:12353073</ref> <ref>PMID:12595305</ref> <ref>PMID:12894857</ref> <ref>PMID:15164384</ref> <ref>PMID:16908819</ref>

AT-III inhibits thrombin, matriptase-3/TMPRSS7, as well as factors IXa, Xa and XIa. Its inhibitory activity is greatly enhanced in the presence of heparin.<ref>PMID:15853774</ref>

+== Publication Abstract from PubMed ==
+Antithrombin, the principal physiological inhibitor of the blood coagulation proteinase thrombin, requires heparin as a cofactor. We report the crystal structure of the rate-determining encounter complex formed between antithrombin, anhydrothrombin and an optimal synthetic 16-mer oligosaccharide. The antithrombin reactive center loop projects from the serpin body and adopts a canonical conformation that makes extensive backbone and side chain contacts from P5 to P6' with thrombin's restrictive specificity pockets, including residues in the 60-loop. These contacts rationalize many earlier mutagenesis studies on thrombin specificity. The 16-mer oligosaccharide is just long enough to form the predicted bridge between the high-affinity pentasaccharide-binding site on antithrombin and the highly basic exosite 2 on thrombin, validating the design strategy for this synthetic heparin. The protein-protein and protein-oligosaccharide interactions together explain the basis for heparin activation of antithrombin as a thrombin inhibitor.
