Illustration of the RA coverage calculation method. To calculate RA coverage, images of the integrin (αvβ5) and paxillin (p-Pax) channels are segmented using the Robust Automatic Threshold Selection method in ImageJ. This method generates binary masks for each channel. The paxillin channel is then subtracted from the integrin channel and results in a mask containing only the RAs. RA coverage is calculated by dividing the area covered by RAs in pixels (integrated density/255) by the area covered by the cell (or cells) in an image.

In this graph, time zero is defined as the arrival of the AP2 signal Right: ITGB5 clusters not stabilized by FCLs disassemble and are removed from the membrane by CME- mediated disassembly (n = 24 events). In this graph, time zero is defined as the disappearance of the ITGB5 signal. Events have been collected from four 1-h long time-lapse acquisitions. Mean ± SEM.
