Signaling proteins are tightly regulated spatially and temporally to perform multiple functions. For Cdc42 and other guanosine triphosphatases, the subcellular location of activation is a critical determinant of cell behavior. However, current approaches are limited in their ability to examine the dynamics of Cdc42 activity in living cells. We report the development of a biosensor capable of visualizing the changing activation of endogenous, unlabeled Cdc42 in living cells. With the use of a… CONTINUE READING
