Constitutively active Cdc42 mutant confers growth disadvantage in cell transformation.

Abstract excerpt

The Rho family small GTPase Cdc42 is critical for diverse cellular functions including the regulation of actin organization, cell polarity, intracellular membrane trafficking, transcription, cell cycle progression and cell transformation. Like other members of the Rho family, Cdc42 cycles between the GTP-bound, active state, and the inactive, GDP-bound state under tight regulation, and it is believed that the GTP...
