Figure 5. — Cytosolic αE-catenin regulates actin-dependent membrane dynamics. (A and B) Representative kymographs of EGFP-actin in membrane protrusions from ActA and β-cat–ActA cells. (A) 2-pixel-wide kymographs were compiled parallel to protrusion direction over 10 min. (B) Number of protrusions per 10-min window (left) and the mean speed of protrusions (right) were measured in ActA and β-cat–ActA cells and shown using a box and whisker plot. 11 cells with 30 protrusions in ActA and 11 cells with 50 protrusions in β-cat–ActA cells were quantified. (C and D) Representative kymographs of membrane protrusions from MDCK and αE-cat shRNA cells (C) and quantification (D). 75 protrusions from 12 MDCK cells and 116 protrusions from 15 αE-cat shRNA cells were measured. Results are presented in a box and whisker format. The ends of the box mark the upper and lower quartiles, the horizontal line in the box indicates the median, and the whiskers outside the box extend to the highest and lowest value within 1.5 times the interquartile range. Outliers are represented as dots. *, P < 0.02; ***, P < 0.0002 (Mann-Whitney test). Bars, 5 µm.
