And what the polypeptide does is it ultimately binds onto a complex that is part of the extrinsic pathway of the blood clotting cascade. So if we think back to the blood clotting cascade we have these two different pathways. We have the intrinsic and the extrinsic pathway and this polypeptide blocks essentially that extrinsic pathway from taking place. So in the extrinsic pathway, we have the tissue factor. The glycoprotein found on the membrane of the endothelium of the blood vessel basically forms a dimer complex with factor seven. And once we form this complex, this complex then reacts with factor ten to basically activate it and begin the final common pathway.
