Riesenprotein Titin ist an der Muskelkontraktion beteiligt: Knäuelmechanismus hilft beim Verkürzen der Fasern

Filamente Aktin und Myosin verrichten mechanische Arbeit nicht allein

(PresseBox) (Bochum, )
Titin, das größte Protein im menschlichen Körper, ist für die Elastizität der Muskeln entscheidend - und für noch mehr, fanden Forscher nun heraus. Ohne Titin könnten unsere Muskeln ein paar Kilogramm weniger stemmen.

Das Riesenprotein Titin ist an der Muskelkontraktion beteiligt, berichten Forscher aus Bochum und New York in der Zeitschrift "Cell Reports". Bislang ging man davon aus, dass zwei andere Proteine allein diese Aufgabe bewerkstelligen.

Die Lehrbuchmeinung lautet: Filamente aus Aktin und Myosin gleiten aneinander vorbei und verrichten so die mechanische Arbeit, die es braucht, um die Muskelfaser zu verkürzen. "Wir haben gezeigt, dass ein weiterer Player beteiligt ist", tkpj Bqmz. Lm. Zmwqyibx Htjia rxu anb Mnbzinkztmhcu Ftrcrldp hcb Ysop-Bmkfzzvkjng Tdruqy.
