title: GTPase regulation: getting aRnd Rock and Rho inhibition.
abstract: Rnd proteins are atypical members of the Rho small G protein family that inhibit the formation of actomyosin contractile fibers via activation of RhoGAPs and inhibition of a Rho effector, the Ser/Thr kinase Rock. These mechanisms might be used to fine-tune Rho GTPase inhibition locally at sites where particular actin structures need to be made.
