Reid Townsend1 International Hupo 2020 The human kinome is comprised of 518 protein and lipid kinases which play a fundamental role in the propagation and integration of cell signaling events. Dysregulation of kinase expression and activity plays a critical role in human disease with >55 kinase inhibitors in the clinic or late-stage trials. Inhibitor resistance develops, in part, due to an adaptive response involving multiple classes of kinases. Yet, comprehensive quantification of cellular kinase levels remains challenging. We report a single LC-MS assay that reproducibly quantifies 976 stable isotope labeled peptides for 367 kinases in a single LC-MS analysis using a new internal standard-triggered acquisition method.
