that the conformational state of C-terminal helix_I is a structural determinant for functional activity. We present an NMR-based conformational assay to monitor the conformation of this crucial helix_I and show that myristate ligands that bend helix_I are functional antagonists, whereas ligands that bind to the myristate pocket but do not induce this conformational change are kinase agonists.
