Fig. 3From: The GPIb-IX complex on platelets: insight into its novel physiological functions affecting immune surveillance, hepatic thrombopoietin generation, platelet clearance and its relevance for cancer development and metastasisMechanoreceptor domains in GPIb. GPIbα contains two mechanosensitive domains (MSD), which support each other in signal transduction. The first domain is located in the leucine-rich repeat domain (LRRD) and the second one is between the macroglycopeptide domain and the trigger sequence. Upon VWF binding and pulling, both domains are unfolded and induce a cooperation for intracellular Ca2+ release, Rac1, LIMK, and platelet activationBack to article page
