New screening method tests the effectiveness of drug compounds that 'glue' proteins together A new screening method that can test the effectiveness of therapeutic molecules designed to 'glue' proteins together in the body has been developed by researchers at the University of Birmingham and the University of Leicester. The research paves the way for drug developers to screen large numbers of potential new drug compounds to discover new treatments for diseases such as breast cancer and Parkinson's disease. The ways in which proteins interact with each other are fundamental to all cell functions. These interactions underpin every function of a healthy body, with any slight change in these interactions resulting in disease.
