    Most potent protein kinase inhibitors act by competing with ATP to block the phosphotransferase activity of their targets. However, emerging evidence demonstrates that ATP-competitive inhibitors can affect kinase interactions and functions in ways beyond blocking catalytic activity. Here, we show that stabilizing alternative ATP-binding site conformations of the mitogen-activated protein kinases (MAPKs) p38α and Erk2 with ATP-competitive inhibitors differentially, and in some cases divergently, modulates the abilities of these kinases to interact with upstream activators and deactivating phosphatases. Conformation-selective ligands are also able to modulate Erk2's ability to allosterically activate the MAPK phosphatase DUSP6, highlighting how ATP-competitive ligands can control noncatalytic kinase functions. Overall, these studies underscore the relationship between the ATP-binding and regulatory sites of MAPKs and provide insight into how ATP-competitive ligands can be designed to confer graded control over protein kinase function.
