Kinome-wide profiling platforms have comprehensively identified the relevant kinases that are targeted by numerous protein kinase inhibitors. However, recent projects have begun to discover non-kinase targets of kinase inhibitors. These non-kinase targets can contribute to the desired or undesired activities of inhibitors, or act as silent bystanders. As a full awareness of a drug's mechanism of action is crucial for the interpretation of results and for successful preclinical and clinical drug development, these discoveries highlight the importance of understanding the pharmacology of kinase inhibitors beyond the kinome. In this Review, I discuss kinase inhibitors for which non-kinase targets have been identified and the application of emerging techniques to validate drug-target engagement in intact cells.
