Enhancing the removal of aggregate-prone toxic proteins is a rational therapeutic strategy for a number of neurodegenerative diseases, especially Huntington’s disease and various spinocerebellar ataxias. This study shows how a compound binding to VCP D1 ATPase enhances proteasomal neurotoxic protein clearance. Furthermore, our proprietary High-Resolution Limited Proteolysis (HR-LiP) technology was used to 3D-map the binding site of the compound under investigation for potential use in neurodegenerative diseases. As a result, we could confidently validate the binding site on the target and explain the observed phenotype.
