Targeted Protein Degradation: From small molecules to complex organelles

Our Special Research Program is a collaborative research platform to unravel how proteins are targeted for degradation. We focus on the two major cellular proteolytic pathways, the ubiquitin-proteasome system (UPS) and autophagy, and the crosstalk between them in the cytoplasm and in the nucleus. Furthermore, we investigate how small molecules can be used to chemically reprogram the degradation systems, enabling the targeted proteolysis of selected proteins in a spatially and temporally controlled manner …
