This invention provides fluorescently-labeled peptide substrates for protein kinases; methods using the substrates for identifying compounds that inhibit protein kinases, for determining if particular protein kinases are active in cells, for diagnosing diseases, and for preparing compositions; and compositions comprising the substrates.

There is widespread interest in developing fluorescentreporters of protein kinase activity, species that can furnish a visual readout of both when and where intracellular kinases are activated in response to a stimulus. We have constructed and identified, via a combination of rational design, library synthesis, and screening, a difluorofluorescein-appended peptide-based species that responds to protein
