dTomato-wGBD sensor localization to membrane protrusions. Live TIRF imaging of membrane protrusions from SUM159 cells expressing either dTomato as a control for cytoplasmic localization or dTomato-wGBD (scale bar, 5 μm). Frames were collected every 30 s (frame rate: 10 frames/second). Associated with Fig. S6 H.
