Disruptive discovery method for inhibitors of protein-protein interactions

Protein-Protein interactions (PPIs) are central to most essential cellular mechanisms including gene expression, protein translocation, cell cycle progression and signal transduction. Bellón-Echeverría et al. published in Scientific Reports a proof of concept employing MultiBacMam to identify new small-molecule inhibitors of the CDK5-p25 protein-protein interaction. The method is generally applicable to any multiprotein cascade important in drug discovery.
