Comments

FUNCTION: 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).
DOMAIN: The N-terminal acidic repeat region mediates, in part, the glycosaminoglycan-accelerated thrombin inhibition (By similarity).
PTM: N-glycosylated; different glycan composition appears to lead to two forms of this protein (56 and 60 kDa).
SIMILARITY: Belongs to the serpin family.
