At Eurofins Advinus we perform Targeted Protein Degradation Assays to help in improving selectivity and reducing drug resistance. There are several challenges that can be faced in PROTAC molecule development phases
- The PROTAC molecule does not bind to its intended partners
- Bringing the E3 ligase and the target protein close to each other does not always lead to ubiquitin-mediated degradation
- The PROTAC molecule leads to ubiquitylation of the target protein, but at the wrong site and/or with the wrong polyubiquitin linkage
