Reorganization of the actin cytoskeleton could coincide with the activation of several seven transmembrane receptors (7TM receptors) (1). Stimulation of Rho family members leads to rapid remodeling of the actin cytoskeleton and subsequent stress fiber formation and certain 7TM receptors were shown to induce Rho-dependent responses via heterotrimeric G-proteins. Gα12, Gα13 as well as Gαq/11 can link 7TM receptors to RhoA activatio...
