subunit has four cysteine-rich regions and a structure similar to other β-integrins. The interaction with collagen leads to stabilization of the platelets. The surface expression of this complex shows high variability, particularly in relation to the polymorphism of GPIa subunit gene. Different
379:. When bound to ADP, conformational changes occur within the aggregin molecule and consequently, it dissociates from the two subunits. Furthermore, the complex can be activated by thrombin. Thrombin binding to its receptor activates 375:. In the resting state the contact between the two protein subunits (necessary for the complex activation) is prevented by aggregin, which disables their contact necessary for the complex activation. The complex can be activated by 99:. Fibrinogen molecules then interconnect the platelets, serving as the basis for platelet aggregation. In the absence of fibrinogen, the platelets are joined by vWF due to its ability to bind the activated GPIIb / IIIa complex. 507:

It plays a key role in their procoagulant activity and subsequent 95:(vWF) results in conformational changes within the GPIb-V-IX complex. In consequence, this complex activates GPIIb / IIIa membrane glycoproteins, allowing them to bind 159:. The binding between GPIbα and vWF mediates the capture of platelets to the injured vascular wall. The deficiency in glycoprotein Ib-IX-V complex synthesis leads to 628: 531:
