Rnd-ing up RhoA Activity to Link Neurogenesis with Steps in Neuronal Migration

Neurogenesis is integrated with neuronal migration to ensure proper development of the cerebral cortex. Reporting in Neuron, Pacary et al. (2011) demonstrate that proneural factors activate atypical Rho GTPases Rnd2 and Rnd3 in newborn cortical neurons, leading to compartmentalized modulation of RhoA signaling and differential control of neuronal migration stages
