The ability of lipid-anchored small GTPases to form nanometer-scale lipid domains on the cell plasma membrane (PM) is precipitating exciting new insights into membrane-anchored protein regulation. A recent article by Remorino et al. demonstrates that Rac1, similar to Ras, forms nanoclusters on the PM. The implications of these findings are discussed herein.
