Figure 2From: Positive regulation of Rho GTPase activity by RhoGDIs as a result of their direct interaction with GAPs Free (non-GTPase-complexed) GDI concentration affects the prolongation of Rho activation in the GDI-integrated model. Rho activation dynamics were simulated at various concentration of free GDI. A) 600Â min after stimulation in the canonical model. B) 600Â min after stimulation in the GDI-integrated model. C) 1,800Â min after stimulation in the GDI-integrated model. The activation levels of GTPases were expressed as the concentration of GTP-Rho/Effector complex.Back to article page
