    The function of a mosquito anticoagulant serpin named as Alboserpin is presented. The recombinant protein binds to phospholipids and it inhibits the activity of human coagulation factor Xa. Binding is highly specific and is not detectable for FX, catalytic site-blocked FXa, thrombin and 12 other enzymes. Alboserpin displays high-affinity binding to heparin, but no change in FXa inhibition was observed in the presence of the cofactor, implying that bridging mechanisms did not take place. Alboserpin displays a potent pharmacological activity since it prevents thrombus formation provoked by ferric chloride injury of the carotid artery and it increases bleeding in a dose-dependent manner.
