Current opinion in cell biology, 1997•ElsevierRho, Rac and Cdc42 are three Ras-related GTP-binding proteins that control the assembly
and disassembly of the actin cytoskeleton in response to extracellular signals. During the
past year, numerous candidate downstream targets for these GTPases have been identified
using affinity chromatography and yeast two-hybrid techniques. These techniques have
revealed that Rho regulates the myosin light chain phosphatase and that Rho and Rac
control the synthesis of phosphatidylinositol 4, 5-bisphosphate, two activities that might help …
