Tumor necrosis factor α stimulation of Rac1 activity: Role of isoprenylcysteine carboxylmethyltransferase
2005, Journal of Biological ChemistryCitation Excerpt :The second interaction of RhoGDI-Rho makes it partially dependent on the confirmation of Rho. RhoGDI interacts preferentially with the GDP-bound form of Rho proteins (46), although equal interactions with both GDP- and GTP-bound forms have been reported in some cases (47, 48). In general, Rac-GDP is considered to be present in a complex with RhoGDI in the cytosol, whereas Rac-GTP is preferentially associated with membranes (43, 49, 50).
