Abstract
The molecular bases of the versatile functions of Rho-like GTPases are
still unknown. Using luciferase assays with rat 3Y1 cells, we found t
hat Rad is integrated downstream of Ras in the TRE (TPA response eleme
nt) activation pathway. Coexpression of a mutant of p65(PAK), PAK/RD,
lacking the kinase domain but containing the Cdc42/Rac interactive bin
ding (CRIB) region, suppressed the TRE activation and cell transformat
ion caused by constitutively activated forms of Ras (RasV12) and Rac1
(Rac1V12). PAK/RD is a good tool to investigate the signaling pathways
in which Rac and Cdc42 are involved. (C) 1997 Federation of European
