Disease

[HEP2_HUMAN] Defects in SERPIND1 are the cause of thrombophilia due to heparin cofactor 2 deficiency (THPH10) [MIM:612356]. A hemostatic disorder characterized by a tendency to recurrent thrombosis.[1][2][3][4]

Function

[HEP2_HUMAN] Thrombin inhibitor activated by the glycosaminoglycans, heparin or dermatan sulfate. In the presence of the latter, HC-II becomes the predominant thrombin inhibitor in place of antithrombin III (AT-III). Also inhibits chymotrypsin, but in a glycosaminoglycan-independent manner.[5] Peptides at the N-terminal of HC-II have chemotactic activity for both monocytes and neutrophils.[6]
