Abstract:A general affinity-based screening assay for discovery of lead compounds binding to potential protein drug targets that is based upon protein thermal unfolding and aggregation is described. ATLAS(Any Target Ligand Affinity Screen) (Anadys Pharmaceuticals, Inc., San Diego, CA) is a simple, homogeneous, and high-throughput affinity-based screening technology that can identify compounds that bind and protect the target protein from thermal unfolding, denaturation, and subsequent aggregation. ATLAS detection of thermally unfolded and aggregated hexahistidine [(His)6]-tagged proteins uses time-resolved fluorescence resonance energy transfer between two anti-(His)6antibodies, labeled with either a donor or acceptor fluorophore, that are simultaneously bound to the aggregated protein. The ATLAS assay is simple to perform and easily automated for screening large compound libraries. The technology is applicable to lead discovery for soluble proteins of known and unknown functions, and particularly for proteins that are difficult to assay functionally. The ATLAS technology has been evaluated using p38 mitogen-activated protein (MAP) kinase as the target protein. Known inhibitors of p38 MAP kinase were examined by ATLAS and a functional assay; the results showed good correlation between the two methods. [ABSTRACT FROM AUTHOR] |
