Fig. 5. SBDS-GFP localizes to the site of incipient lateral pseudopod formation, remains localized in the pseudopod during extension and exits the pseudopod upon retraction. (A,B) Two representative examples of localization. Small arrows point to SBDS-GFP localization in lateral pseudopods. Large arrows indicate direction of spatial gradients. Time is given in seconds (s); a, anterior end; u, uropod. Bar, 5 µm.
