3NID, 3NIF, 3NIG - PubMed Abstract: 
The platelet integrin α(IIb)β(3) is essential for hemostasis and thrombosis through its binding of adhesive plasma proteins. We have determined crystal structures of the α(IIb)β(3) headpiece in the absence of ligand and after soaking in RUC-1, a novel small molecule antagonist ...
