Guanosine Diphosphate 21-24 cell division cycle 42 Homo sapiens 15-20 11285260-4 2001 Here, we report that retaining Cdc42 in its GDP-bound state by overexpressing Rho-GDI inhibits Ras-GRF-mediated MAPK activation. Guanosine Diphosphate 44-47 cell division cycle 42 Homo sapiens 31-36 11285260-7 2001 In contrast, promoting GDP release from Cdc42 with the Rho family GEF Dbl or with ionomycin suppressed the restraint exerted by Cdc42 on Ras-GRF activity. Guanosine Diphosphate 23-26 cell division cycle 42 Homo sapiens 40-45 11285260-7 2001 In contrast, promoting GDP release from Cdc42 with the Rho family GEF Dbl or with ionomycin suppressed the restraint exerted by Cdc42 on Ras-GRF activity. Guanosine Diphosphate 23-26 cell division cycle 42 Homo sapiens 128-133 11285260-9 2001 Interestingly, the loss of the GDP-bound state by Cdc42 abolishes its inhibitory effects on Ras-GRF function. Guanosine Diphosphate 31-34 cell division cycle 42 Homo sapiens 50-55
