Figure 7. Association of GAPA with activated Rac GTPases.

Figure 7

A. Interaction of GFP-tagged Rac proteins with GST-GRD in a pulldown experiment. Upper panel (pull down), GFP-fusions pulled down using GST-GRD; lower panel (input) showing whole cell lysates probed for the GFP-fusion proteins. B. Interaction of constitutively activated Racs with GRD in a yeast two-hybrid assay represented in a table. C. GFP-GAPA associates preferentially with activated Rac1a. Filamin is also present in the complex. GFP-GAPA and Filamin were recognized using appropriate antibodies, GST-Rac1a using GST polyclonal antibodies. D. Pulldown of Filamin using GST-Rac1a. Rac1a could pull down GFP-FLN which was recognized by mAb K184-3, GST and GST-Rac1a were visualised by Ponceau S staining.
