Abstract: Cell-based screening methods for determining kinase activity are provided. The methods utilize existing cellular pathways that are regulated by kinases. In one embodiment, various components of a ubiquitin-mediated degradation pathway are modified to create an assay that can be used to screen for a molecule that modulates the activity of a kinase of interest that otherwise does not regulate the degradation pathway. In another embodiment, various components of a protein translocation pathway are modified to screen for a molecule that modulates the activity of a kinase of interest that otherwise does not regulate the translocation pathway.

Abstract: Driven by the influx of data from genome sequencing projects, systematic efforts are now underway to construct defined sets of cloned genes for high throughput expression and purification of recombinant proteins. To facilitate the subsequent study of protein function, the present invention provides protein microarrays that are compatible with the demand for extremely low sample volume and the rapid, simultaneous processing of thousands of proteins, and methods of assaying these arrays. The proteins are covalently or non-covalently attached to the surface of a solid support and retain their ability to interact specifically with other proteins, polynucleotides, other biological macromolecules, or small molecules.
