Abstract

Microarray-based kinomics, which measure the enzymatic activity or the presence of intracellular protein kinases, are now regarded as alternative tools to conventional mass spectrometry-based kinomics for examining intracellular kinomics. Here, we reviewed the principal advantages, recent progress, and remaining problems of representative microarray- based kinomics, including substrate peptide and protein microarrays, anti-protein kinase antibody microarrays, and reverse protein microarrays. Microarray-based kinomics are not as good at quantitative evaluation of kinomics as the conventional mass spectrometry-based kinomics. However, their simplicity and high throughput make the microarraybased kinomics unique tools, being especially suited for a practical analysis; monitoring drug effects on cellular kinomics as a tool for drug development, and for the diagnosis and prognosis of diseases based on kinomics.
