It is essential for the final stage of cell division, the formation of vesicles, the release of viruses, and membrane repair. Distinct from other cytoskeletal filaments, ESCRT-III filaments do not consume energy themselves, but work in conjunction with another ATP-consuming complex. Despite rapid progress in describing the cell biology of ESCRT-III, we lack an understanding of the physical mechanisms behind its force production and membrane remodelling.\r\nResults\r\nHere we present a minimal coarse-grained model that captures all the experimentally reported cases of ESCRT-III driven membrane sculpting, including the formation of downward and upward cones and tubules. This model suggests that a change in the geometry of membrane bound ESCRT-III filaments—from a flat spiral to a 3D helix—drives membrane deformation. We then show that such repetitive filament geometry transitions can induce the fission of cargo-containing vesicles.\r\nConclusions\r\nOur model provides a general physical mechanism that explains the full range of ESCRT-III-dependent membrane remodelling and scission events observed in cells. This mechanism for filament force production is distinct from the mechanisms described for other cytoskeletal elements discovered so far. The mechanistic principles revealed here suggest new ways of manipulating ESCRT-III-driven processes in cells and could be used to guide the engineering of synthetic membrane-sculpting systems.","lang":"eng"}],"file_date_updated":"2021-11-26T11:37:54Z","_id":"10354","oa":1,"scopus_import":"1","publication":"BMC Biology","language":[{"iso":"eng"}],"publication_status":"published","file":[{"date_created":"2021-11-26T11:37:54Z","access_level":"open_access","checksum":"31d8bae55a376d30925f53f7e1a02396","file_id":"10356","file_name":"2019_BMCBio_Harker_Kirschneck.pdf","creator":"cchlebak","content_type":"application/pdf","date_updated":"2021-11-26T11:37:54Z","success":1,"relation":"main_file","file_size":1648926}],"pmid":1,"article_processing_charge":"No","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","publisher":"Springer Nature","day":"22"}
