anfibatide

Anfibatide is an anticoagulant C-type lectin-like protein purified from the venom of the sharp-nosed viper (Deinagkistrodon acutus). […] The anticoagulant activity of anfibatide is due to its strong binding to human platelet glycoprotein Ib α-chain (GPIbα), which inhibits the binding of GPIbα with von Willebrand factor (VWF) and thrombin (Fig. 6a).
