Coordination of Rho GTPase activities during cell protrusion

The Rho GTPase family is involved in the control of cytoskeleton dynamics, but the spatiotemporal coordination of each element (Rac1, RhoA and Cdc42) remains unknown. Here, GTPase coordination in mouse embryonic fibroblasts is examined both through simultaneous visualization of two GTPase biosensors and using a computational approach.
