The main component of the environment surrounding cells is the extracellular matrix (ECM), a complex network of secreted macromolecules such as collagen, laminin and fibronectin 1, 2. To sense and interact with the extracellular environment, cells exploit both integral and peripheral membrane proteins and establish defined domains at the plasma membrane to mediate processes like signalling, endocytosis and mechanotransduction. We here define the molecular mechanism regulating the functional interplay between FAs and plaques and propose that clathrin-coated plaques act as regulators of cell migration promoting contact guidance-mediated collective migration in a cell-to-cell contact independent manner.Įach cell is surrounded by a plasma membrane composed of lipids that separates the intracellular milieu from the extracellular space. Using a genetic silencing approach to abrogate plaque formation and 3D-micropatterns to spatially control the location of clathrin-coated plaques, we could directly correlate cell migration directionality with the formation of clathrin-coated plaques and their ability to recognize extracellular topographical cues. We identify Eps15 and Eps15R as key regulators for the formation of clathrin-coated plaques at locally remodelled ECM sites. We show that in migrating cells, FAs digest the ECM creating extracellular topographical cues that dictate the future location of clathrin-coated plaques. ![]() We revealed that plaque formation is intimately linked to extracellular matrix (ECM) modification by focal adhesions (FAs). Here, we study the origin and function of clathrin-coated plaques during cell migration. However, the molecular origin leading to their formation and their precise functions remain to be determined. Previous studies suggested an involvement of plaques in cell adhesion. On the contrary, the role of large flat clathrin arrays, called clathrin-coated plaques, remains ambiguous. The function of curved clathrin-coated pits in forming endocytic structures is well studied. Depending on this, our products are sold very well in the countries in Africa, the Mid-East and Southeast Asia.Clathrin is a unique scaffold protein, which forms polyhedral lattices with flat and curved morphology.
