Abstract:
Protein-Protein Interactions (PPI) mediate most of the vital processes in cells and are involved in numerous diseases. However, it is extremely challenging to make them drug targets. The research in our lab focuses on using peptides for the quantitative biophysical and structural analysis of PPI in health and disease. Based on this, we develop lead peptides that modulate PPI for therapeutic purposes. In addition, peptides are used for biosensing based on specific PPI. In my talk I will give an overview of our research, including recent examples for PPI-targeting and sensing peptides developed in our lab:
- Control of condensation and aggregation of proteins by multiphosphorylation(1,2).
- Inhibiting structured and disordered domains simultaneously (3)
- Specific targeting of cancer cells by a designed peptide (4)
- Inhibiting and quantifying protein aggregation in disease (5,6).
