Popis: We resolved the organization of subunits in cytoskeletal polymers in cells by light microscopy. Septin GTPases form linear complexes of about 32 nm length that polymerize into filaments. We visualized both termini of septin complexes by single molecule microscopy in vitro. Complexes appeared as 32 nm spaced localization pairs, and filaments appeared as stretches of equidistant localizations. Cellular septins were resolved as localization pairs and thin stretches of equidistant localizations.
