Abstract

Rho GTPases during cell protrusion The Rho GTPase family acts in concert to regulate cyoskeletal dynamics during processes such as cell motility. In this study, Danuser and colleagues study the coordination of RhoA, Rac1 and Cdc42 during cell migration by simultaneously visualizing two molecules using complementary biosensor designs, and by computationally defining the relationships between individual molecules visualized in separate cells. The latter approach demonstrates that different biosensors, imaged separately, can be freely combined to produce maps of relative signalling activities with seconds and single-micron resolution. These technologies pave the way to defining the dynamics of many proteins in large signal transduction networks.
