Proteine, die Bausteine des Lebens, sind komplexe Moleküle. Ausgangspunkt ihrer Entstehung in der Zelle ist die DNA. Diese enthält alle genetischen Informationen eines Organismus und somit auch die 'Baupläne' für verschiedenste lebenswichtige Proteine. Der Weg vom 'Bauplan' bis zum fertigen Protein ist aber ein mehrstufiger und daher fehleranfälliger Prozess. Eine Forschungsgruppe am Cold Spring Harbor Laboratory (CSHL) in New York ist jetzt einem Mechanismus auf die Spur gekommen, der wesentlich zur Qualitätskontrolle auf dem Weg zur Proteinherstellung beiträgt. In der Online-Ausgabe der renommierten Zeitschrift "Cell" werden die neuen Forschungsergebnisse vorgestellt. Erstautor der Studie ist Dr. Claus D. Kuhn, der seit nmnzdt ftm Ajzsi um Fgwlbemirnhywesbw wxs Eat-Ompysbbhydbhq (NBTxhe) lor Ncjwulkataj Ogxxtrlo xmhntj.
