Potently induces platelet aggregation of washed human platelet and platelet-rich plasma in a concentration-dependent manner. It acts by binding to GPVI (GP6), leading to kinases-dependent exposure of functional alpha-IIb/beta-3 and platelet aggregation, and also induces metalloproteinase-dependent GP6 shedding from platelets. Hexamer of heterodimers of subunits alpha and beta (alphabeta)(6); disulfide-linked. Expressed by the venom gland. Does not bind to GPIb and alpha-2 integrin. Does not agglutinate the formalin-fixed platelets, even at high concentrations (PubMed:18221359). Belongs to the snaclec family.
