Plasma membrane tension strongly affects cell surface processes, such as migration, endocytosis and signalling. However, it is not known whether membrane tension of organelles regulates their functions, notably intracellular traffic. The ESCRT-III complex is the major membrane remodelling complex that drives Intra-Lumenal Vesicle (ILV) formation on endosomal membranes. Here, we made use of a fluorescent membrane tension probe to show that ESCRT-III subunits are recruited onto endosomal membranes when membrane tension is reduced. We find that tension-dependent recruitment is associated with ESCRT-III polymerization and membrane deformation in vitro, and correlates with increased ILV formation in ESCRT-III decorated endosomes in vivo. Finally, we find that endosomal membrane tension decreases when ILV formation is triggered by EGF under physiological conditions. These results indicate that membrane tension is a major regulator of ILV formation and of endosome trafficking, leading us to conclude that membrane tension can control organelle functions.
