Table 1 Summary of interactions of RhoGDIs with Rho GTPases. Interaction of TbRhoGDI and LyGDI with Rho GTPases was determined using a yeast two-hybrid assay (Fig. 5A). Interaction of bovine RhoGDI with the indicated Rho GTPases was determined in translocation experiments (Fig. 5C). Data on Dictyostelium RhoGDI1 was taken from Rivero et al. , except for the interactions with TbCdc42 and ScCdc42. DdRacF1 was used in yeast two-hybrid experiments, whereas DdRacF2 was used in translocation experiments. NA, not assayed.
