Figure 5. G-Clathrin with Arf6(Q67L) has slowed FRAP recovery, consistent with longer coated membrane lifetime.
Cells were transfected with GFP-clathrin alone (red, circles) or co-transfected with GFP-clathrin and Arf6(Q67L) (blue, squares) or Arf1() (green, triangles). Following an initial continuous image stream (30 frames at 30 ms exposure), 50 pixel square regions were photobleached and recovery in G-clathrin monitored by capturing 1 sec streams (as above) every 5 s for the first 30s (see Methods for details). Inset: Recovery curves obtained over 180 sec, in which 1 sec streams were taken every 5 s for the first 30s, and then every 20s for the duration.
