GP5

A gene on chromosome 3q29 that encodes a protein which is part of the Ib-V-IX system of platelet surface membrane glycoproteins, which comprise the von Willebrand factor receptor and mediate adhesion of platelets to injured vascular surfaces with circulation, a critical event in haemostasis.

The advanced maturation state of megakaryocytes from stressed mice suggested by morphological examination was sustained by the enhanced expression of lineage differentiation marker CD42d (Figure 6(f), p <0.01).
This disease is caused by mutations in one of the three genes coding for the glycoprotein complex (GP)-IX-V 1b (CD42b-CD42a, CD42d), which function as a receptor for vWF, also affecting platelet adhesion and aggregation.
