Clathrin-mediated endocytosis (CME) is an essential, highly conserved process in eukaryotic cells that facilitates the internalization of plasma membrane components, transmembrane proteins and extracellular nutrients. This complex pathway involves the concerted assembly and disassembly of many different proteins at the plasma membrane. Budding yeast has served as a powerful model for dissecting CME through combined genetic, biochemical, quantitative imaging and mathematical approaches. In this Cell Science at a Glance article, we integrate decades of quantitative data to generate a three-dimensional molecular animation depicting the full progression of CME in budding yeast (Movie 1). The animation and accompanying poster capture the spatial and temporal dynamics of key protein players. In addition, we highlight recent advances in understanding of the condensation of endocytic proteins into distinct sites and the organization of actin networks that generate the forces necessary to deform and internalize the membrane against the high internal turgor pressure of the budding yeast cell.
