In the early phase of primary hemostasis, platelets adhere to damaged blood vessel walls by binding via the CD42 complex, also designated platelet glycoprotein (GP) complex, to the von Willebrand factor (vWf) protein, which is exposed on the subendothelium (1-3). The CD42 complex contains four subunits, CD42b (GPIb alpha) and CD42c (GPIb beta), which are linked by a disulfide bridge, and CD42a (GPIX) and CD42d (GPV), which are noncovalently linked to the complex (1-4). The CD42 complex is specifically expressed in platelets and megakaryocytes (5). Cleavage of CD42d by thrombin produces a soluble fragment and a membrane associated fragment, which merits CD42d as a useful marker for platelet activation by thrombin (7). The gene encoding human CD42d maps to chromosome 3q29 (8).
