Arbeitsweise des Proteins Channelrhodopsin-2 entschlüsselt

Forscher verfolgen das Öffnen des Ionenkanals mit biophysikalischen Methoden: Die Ergebnisse erlauben Maßanfertigung optogenetischer Werkzeuge

(PresseBox) (Berlin, )
Mit hoher räumlicher und zeitlicher Präzision haben Forscher die Arbeitsweise des lichtgesteuerten Ionenkanals Channelrhodopsin-2 aufgeklärt. Dieses Biomolekül kommt in der Optogenetik zum Einsatz, welche es erlaubt, die Aktivität von lebenden Zellen mit Licht zu steuern. Bochumer Wissenschaftler um Klaus Gerwert berichten gemeinsam mit Kollegen der Humboldt-Universität (HU) um Peter Hegemann und der Charité um Franz Bartl in der Zeitschrift "Angewandte Chemie " über ein Modell der Channelrhodopsin-Aktivierung, das in Zukunft erlauben wird, diese Proteine maßgeschneidert zu modifizieren.

Das von Peter Hegemann (HU) in Grünalgen entdeckte Channelrhodopsin-2 ist das zentrale lichtaktivierbare Kanalprotein in der Optogenetik.
