WebSep 20, 1996 · Our results indicate that IQGAP is the target for Rac1 and Cdc42 and suggest that IQGAP is involved in the insulin- and Rac1-induced membrane ruffling. The targets for Cdc42 and Rac1 are identified as PAK ( 19, 20, 21 ), phosphatidylinositol 3′-kinase ( 22, 23 ), and WASP ( 24, 25 ). WebDec 15, 2002 · The actin cytoskeleton plays an important role in defining cell shape and morphology. Actin-rich filopodia and lamellipodia protrusions are thought to depend on the activation of small guanosine triphosphatases (GTPases) of the Rho subfamily, Cdc42 and Rac1, respectively.1,2 In platelets, stimulation by thrombin induces filopodia extension …
