Abstact

Targeting kinases outside the highly conserved ATP pocket is thought to be a promising strategy for overcoming bottlenecks in kinase inhibitor research, such as limited selectivity and drug resistance. Here we report the development and application of a direct binding assay to detect small molecules that stabilize the inactive conformation of the tyrosine kinase cSrc. Protein X-ray crystallography validated the assay results and confirmed an exclusively allosteric binding mode.
