Using Structural Biology to Understand Cell Signalling

Welcome to the Guettler Lab! We employ biochemistry, structural biology and cell biology to study the molecular mechanisms of Wnt/beta-catenin signalling and telomere homeostasis, with a particular focus on how poly(ADP-ribosyl)ation (PARylation) controls both processes. Besides understanding fundamental mechanisms of cell function, we aim to uncover novel potential therapeutic avenues in cancer.
