Snaclec that induces human platelet aggregation in the absence of any cofactor with the EC(50) of 0.25 nM and causes tyrosine phosphorylation in human platelets. Antibodies against either platelet GPIbalpha (GP1BA) or GPVI (GP6) inhibit alboaggregin D-induced platelet aggregation. Only the combination of these two antibodies completely inhibit aggregation, suggesting that it acts through both GPIbalpha (GP1BA) and GPVI (GP6). Tetramer of heterodimers of alpha and beta subunits (alphabeta)(4); disulfide-linked. Expressed by the venom gland. Belongs to the snaclec family.
