Das Protein p53 spielt eine essentielle Rolle in der Krebsentstehung. Es verhindert, dass aus einer gesunden Zelle eine Krebszelle wird, indem es bei Schädigungen des Erbguts den kontrollierten Zelltod einleitet. Das Hitzeschockprotein Hsp90 wiederum aktiviert und stabilisiertp53. Nun haben Wissenschaftler der Technischen Universität München (TUM) aufgeklärt, wo und mit welchen Mechanismen die beiden Proteine interagieren. Über ihre Ergebnisse berichten sie in der aktuellen Ausgabe der Zeitschrift Nature Structural and Molecular Biology.
In jeder Zelle gibt es Tausende von Proteinen, deren Aktivität und Lebensdauer reguliert werden müssen, um den Lebenszyklus der Zelle von der Zellteilung bis zum Zelltod zu steuern.
