Snaclec that binds to von Willebrand factor (VWF) and induces its interaction with GPIbalpha (GP1BA) (via the vWF A1 domain), resulting in platelet aggregation. Intramuscular and intravenous injections in mice induce a dose-dependent drop in platelet count (thrombocytopenia). Pretreatment by intravenous injection by this protein in mice potentiates the hemorrhagic lesion in the skin provoked by the metalloproteinase BaP1 intradermally injected. This result is not observed when both BaP1 and this protein are injected simultaneously. Heterodimer; disulfide-linked. Expressed by the venom gland. Belongs to the snaclec family.
