FIGURE 4:

Effects with an alternate dynamin construct lacking the PHD on native membranes. (A) The ΔPH-6xK construct has the entire PH domain deleted and replaced with a 6xLys linker. (B) Fluorescence micrographs showing WT and ΔPH-6xK on a p-Texas Red DHPE–labeled membrane tube composed of BPLE. White arrowheads mark sites of tube constriction. Scale bars, 5 μm. (C) Kymographs of scaffold assembly–induced tube constriction for WT and ΔPH-6xK on BPLE. Data are acquired in the tube fluorescence channel, and the decay in fluorescence intensity reflects assembly-induced constriction of the tube underlying the scaffold. (D) Single-pixel tube fluorescence changes in response to GTP addition to WT (blue) and ΔPH-6xK (red) scaffolds on BPLE. Fission time represents time between onset of constriction and the cut in the tube. (E) Fission time for WT and ΔPH-6xK. Data represent mean ± SD (n ≥15, N = 1, Student’s t test).
