Plasma membranes are organized into domains of different protein and lipid composition. Eisosomes are key complexes for yeast plasma membrane organization, containing primarily Pil1 and Lsp1. Here we show that both proteins consist mostly of a banana-shaped BAR domain common to membrane sculpting proteins, most similar to the ones of amphiphysin, arfaptin 2 and endophilin 2. Our data reveal a previously unrecognized family of BAR-domain proteins involved in plasma membrane organization.
