RT   "The highly specific platelet glycoprotein (GP) VI agonist trowaglerix
RT   impaired collagen-induced platelet aggregation ex vivo through matrix
RT   metalloproteinase-dependent GPVI shedding.";
RL   J. Thromb. Haemost. 6:669-676(2008).
CC   -!- FUNCTION: Potently induces platelet aggregation of washed human
CC       platelet and platelet-rich plasma in a concentration-dependent manner.
CC       It acts by binding to GPVI (GP6), leading to kinases-dependent exposure
CC       of functional alpha-IIb/beta-3 and platelet aggregation, and also
CC       induces metalloproteinase-dependent GP6 shedding from platelets.
CC       {ECO:0000269|PubMed:18221359}.
CC   -!- SUBUNIT: Hexamer of heterodimers of subunits alpha and beta
CC       (alphabeta)(6); disulfide-linked. {ECO:0000269|PubMed:18221359}.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC   -!- MASS SPECTROMETRY: Mass=16800; Method=MALDI;
CC       Evidence={ECO:0000269|PubMed:18221359};
CC   -!- MISCELLANEOUS: Does not bind to GPIb and alpha-2 integrin. Does not
CC       agglutinate the formalin-fixed platelets, even at high concentrations
CC       (PubMed:18221359). {ECO:0000305|PubMed:18221359}.
CC   -!- SIMILARITY: Belongs to the snaclec family. {ECO:0000305}.
