Wissenschaftler entdecken Signale für den gezielten Proteinabbau

(PresseBox) (Freiburg, )
Alles Leben ist abhängig von Proteinen, die in den Zellen nach dem Bauplan der Gene zusammengesetzt werden. Während viele Forscherinnen und Forscher untersuchen, wie die Menge und die Aktivität von Proteinen reguliert werden, ist bislang weniger gut bekannt, welche Signale zu einem gezielten Abbau bestimmter Proteine führen. Ein Forschungsteam um den Freiburger Biologen Prof. Dr. Ralf Reski hat nun Substrate und Interaktionspartner gefunden, die im Moos Physcomitrella patens den Proteinabbau nach der so genannten N-end Rule ermöglichen. Diese beschreibt den Einfluss, den eine bestimmte Aminosäure, die sich am Anfang eines Proteins befindet, auf dessen Abbaugeschwindigkeit hat. Das Team hat die
