Abstract

Glycoprotein (GP) Ib-IX-V is a remarkable platelet adhesion receptor of the leucine-rich repeat family. It has evolved to fulfil its major function of initiating platelet aggregation (thrombus formation) at high-shear stress in flowing blood. In addition to binding von Willebrand factor (vWF) in subendothelial matrix or plasma to trigger platelet aggregation, GPIb-IX-V also binds counter-receptors, αMβ2 (Mac-1) on neutrophils or P-selectin on activated platelets or endothelial cells. GPIb-IX-V ligands also include α-thrombin, clotting factors XI/XIIa, and high-molecular-weight kininogen. Interactions involving GPIb-IX-V are therefore central to vascular processes of thrombosis and inflammation, and the receptor is under intense scrutiny as a potential therapeutic target.
