Supplemental Movie 1

Dynamics of eGFP-tagged FGFR wild type and activating mutants in Ishikawa cells. Spinning disk confocal microscopy time-lapse images of Ishikawa cells stably expressing eGFP-tagged FGFR wild type (left panel), or activating mutants; N550K (middle panel), Y376C (right panel). Images were acquired every 2 seconds for 1 minute. The video plays at 10 frames s^-1 and is thus accelerated 20 times
