Abstract
Kinases represent one of the most important target classes of current drug discovery efforts. However, because the vast majority of potential small-molecule therapeutics is directed toward the highly conserved ATP-binding cleft, kinase inhibitors often exhibit significant unintended off-target effects. A recent report describes a chemical proteomics methodology that enables the simultaneous in vivo quantification of the on- and off-binding targets of kinase inhibitors across hundreds of nucleotide-dependent enzymes.
