CDC42 is a member of the Rho family of GTPases and is part of cellular pathways fundamental to growth, differentiation and apoptosis. Downstream targets for CDC42 include those that regulate the actin cytoskeleton (e.g. WASP) and cellular stress pathways (e.g. PAK) as well as the coatomer protein complex and PAR6. CDC42 is involved in the G(1)-S progression of the cell cycle. CDC42 and its downstream effector mDia3 are involved in bi-orientation and stabilization of spindle microtubules attachment to kinetochores and regulate chromosome alignment and segregation during mitosis.
Rho GTPases including Rho, Rac and Cdc42 are involved in cell morphogenesis by inducing specific types of actin cytoskeleton and alignment and stabilization of microtubules. Previous studies suggest that they also regulate cell cycle progression; Rho, Rac and Cdc42 regulate

The Rho family member Cdc42 can signal through a number of cellular pathways fundamental to growth, differentiation and apoptosis. Recently, information has come at an impressive pace, both with regard to previously identified targets for Cdc42 that regulate the actin
