Claudine sind essentielle tight junctions Transmembranproteine in Vertebraten und sind lebensnotwendig in septate junctions von Invertebraten. Während in Vertebraten 24 Proteine zur Gruppe der Claudine zählen, konnte in dieser Arbeit durch Sequenzvergleiche sowie genetische und molekularbiologische Methoden die Gruppe der Claudine auf die Proteine Megatrachea, Sinuous und Sesam eingegrenzt werden. Die molekulare Analyse von sesam Allelen führte zur Identifizierung lebenswichtiger Aminosäurren im exterazellulären Bereich von Sesam. Eine der Mutationen führte zum Austausch einer Aminosäure in einem von Vertebraten bis Invertebraten konservierten Proteinmotivs und unterstreicht damit die essentielle Bedeutung dieses Motivs. Neben der gleichen...
