The movie shows the complete experiment from which the data in fig 6 was constructed. Three movie sequences of images of a RAW 264.7 cell expressing C-terminally tagged ezrin-GFP and loaded with the Ca2+ indicator fura-red are shown. The first sequence shows the phase contrast images (PContrast): the second the ezrin distribution; and the third the fura red intensity which decreases with an elevation of cytosolic Ca2+.
