Neue Erkenntnisse über Fehlfaltung von Proteinen

(PresseBox) (Berlin-Buch, )
Verschiedene neurodegenerative Erkrankungen wie die Spinozerebelläre Ataxie (SCA) oder Chorea-Huntington entstehen dadurch, dass sich bestimmte Eiweiße, darunter ein Protein namens Ataxin-1, falsch zusammenlagern. Forscher des Max-Delbrück-Centrums für Molekulare Medizin (MDC) Berlin-Buch haben nun gemeinsam mit Kollegen von der Université Paris Diderot, Paris, Frankreich, 21 andere Eiweiße identifiziert, die dazu beitragen oder verhindern, dass Ataxin-1 schädliche Strukturen ausbildet. (PLoS Genetics, doi: 10.1371/journal.pgen.1002897)*.

Ein Protein kann seine Funktion nur dann richtig erfüllen, wenn sich die lange Kette aus seinen Bausteinen, den Aminosäuren, richtig faltet. Ist die Faltung fehlerhaft, kann das Protein giftig für den Körper sein und mit anderen Proteinen zu Aggregaten tzmlazwmnv.
