Abstract:
Clathrin-coated structures are the best characterized endocytic carriers, but the mechanism through which clathrin-coated plaques perform endocytic functions is still debated. We developed novel experimental and analytical approaches that allow us to dissect the mechanism of plaque growth and disassembly with high spatial and temporal resolution. We found that clathrin and its primary adaptor protein (AP2) are incorporated to the plaques at the peripheral regions. Patches of clathrin coats are internalized also from the peripheries. Our results show that the peripheral regions of plaques are active endocytic sites whereas the central regions are more stable.
