Teilprojekt B10 - Charakterisierung der DNA-Bindungsdomäne und akzessorischer Faktoren des MLL-Proteins, eines Mitglieds der Trithorax Gruppe von Chromatin Organisator-Proteinen

Die übergeordnete Fragestellung des Teilprojektes B10 untersucht den onkogenen Mechanismus von Fusionsproteinen, die bei speziell bei Kleinkindern aggressive Leukämien auslösen. Diese Fusionsproteine (MLL Fusionsproteine) entstehen durch chromosomale Translokationen am Lokus 11q23. Sie stellen aberrante Transkriptionsfaktoren dar, die durch eine Veränderung der DNA-Struktur wirken und so ein onkogenes Programm der Genexpression auslösen.
