Figure 9. Differential interaction of endogenous Sept9 isoforms with microtubules and F-actin.

Figure 9

(a) SKBr3 cell lysates were incubated with either paclitaxel or phalloidin to polymerize tubulin or G-actin, respectively. After high-speed centrifugation through a sucrose cushion, supernatant and pellet proteins were separated and equivalent amounts of each fraction were analyzed by Western blotting with the indicated antibodies and distribution of each protein in pellets (P) and supernatants (S) was quantified. The percentage of each analyzed protein in the pellets was compared to (b) the percentage of tubulin present in the paclitaxel-microtubule pellets or to (c) the percentage of actin present in the phalloidin-F-actin pellets. Results are from three independent experiments, mean ± S.D.; t-test, *p value < 0.05, **p value < 0.01, ***p value < 0.001. Blot images in panels a) were cropped, full blot images are presented in Supplementary Fig. S8.
