This study reveals a novel function of the Rho GTPase-activating protein called α2-chimerin in cortical development, where acute knockdown of α2-chimerin caused neuronal migration deficit and cortical circuit malformation in the developing mouse brain. This developmental defect was also associated with an impairment of circuit development causing epileptic discharges in adult animals.
