Figure S3. Effect of Rab GAPs blocking Shiga toxin uptake on the Rab6 effector Bicaudal-D1. HeLa cells cotransfected for 24 h with the GFP-tagged Rab GAPs (green) indicated in the figure and myc-tagged Bicaudal-D1 (red) were fixed and stained with mouse anti-myc antibodies and Cy3-conjugated anti-mouse secondaries. DNA was stained with DAPI (blue). Bar, 10 µm.
