Zusammenfassung

Viele Zelltypen in mehrzelligen Organismen weisen eine ausgeprägte Polarität auf, die für die Funktion der Zellen von größter Bedeutung ist. Die Kontrolle der Zellpolarität erfolgt durch ein evolutionär hochkonserviertes Netzwerk interagierender Proteine.

Abstract

Many cell types in multicellular organisms possess a pronounced polarity that is of great importance for the function of the cells. Cell polarity is controlled by an evolutionarily conserved network of interacting proteins.

Additional information

Die Arbeitsgruppe von Andreas Wodarz befasst sich mit verschiedenen Aspekten der Zellpolarität. Insbesondere ist sie an den molekularen Mechanismen interessiert, die die Etablierung und Aufrechterhaltung der apiko-basalen Zellpolarität in Epithelien und neuralen Vorläuferzellen der Taufliege Drosophila steuern.
