Description: Rho family GTPases are signaling molecules that orchestrate cytoskeletal dynamics in a variety of cellular processes. Because they effect localized changes to the cytoskeleton only in their active (GTP-bound) conformation, the ability to monitor the active state of Rho GTPases in space and time is critical for understanding their function. Here, we summarize popular tools used for live imaging of active Rho GTPases, outlining advantages and drawbacks of these approaches. Additionally, we highlight key features of the Xenopus laevis embryo that make it well-suited for epithelial cell biology and discuss how application of Rho activity reporters in the Xenopus laevis embryo led to the discovery of a novel phenomenon, junctional Rho flares.
