| ==Overview==
| |
| Hsp90 encodes a ubiquitous molecular chaperone protein conserved among, species which acts on multiple substrates, many of which are important, cell-signaling proteins. Inhibition of Hsp90 function has been promoted as, a mechanism to degrade client proteins involved in tumorigenesis and, disease progression. Several assays to monitor inhibition of Hsp90, function currently exist but are limited in their use for a drug discovery, campaign. Using data from the crystal structure of an initial hit, compound, we have developed a fluorescence polarization assay to monitor, binding of compounds to the ATP-binding site of Hsp90. This assay is very, robust (Z' > 0.9) and can detect affinity of compounds with IC50s to 40, nM. We have used this assay in conjunction with cocrystal structures of, ...
