Abstract

Background: During thrombus formation, platelet integrin α_IIb β₃ binds fibrin; however, the mechanism of this interaction is unclear. Results: Mutations of discontinuous negatively charged and aromatic residues in the α _IIb β-propeller domain impair fibrin clot retraction and cell adhesion. Conclusion: Integrin α_IIb β₃ has multiple binding sites for fibrin. Significance: Uncovered recognition specificity of α_IIb β₃ for fibrin may be used to select inhibitors of this interaction.
