Endocytic Trafficking of Rac Is Required for the Spatial Restriction of Signaling in Cell Migration

The small GTPases, Rab5 and Rac, are essential for endocytosis and actin remodeling, respectively. Coordination of these processes is critical to achieve spatial restriction of intracellular signaling, which is essential for a variety of polarized functions. Here, we show that clathrin- and Rab5-med...
