Fig. 8. Effect of membrane targeted centaurin-
2 and its mutants on ARF6 activation by cytohesin 2CAAX. HeLa cells were transiently transfected with the indicated expression vectors. After 2 days, the cells were serum starved, fixed, immunostained with an anti-HA antibody and imaged using a confocal microscope. Images are representative of 90-95 transfected cells from three experiments.
