- 08:27Conclusion
Septine sind Zytoskelettproteine. Sie interagieren mit Lipidmembranen und können Membrankrümmungen im Mikrometerbereich wahrnehmen, aber auch erzeugen. Wir beschreiben in diesem Protokoll Bottom-up-In-vitro-Methoden zur Analyse von Membranverformungen, krümmungsempfindlicher Septinbindung und Septinfilament-Ultrastruktur.
