Steroid hormone receptor-mediated reporter assays in the budding yeast Saccharomyces cerevisiae have been an invaluable tool for the identification and functional characterization of steroid hormone receptor-associated chaperones and cochaperones. This chapter describes a hormone-inducible androgen receptor-mediated beta-galactosidase reporter assay in yeast. In addition, the immunophilin FKBP52 is used as a specific example of a receptor-associated cochaperone that acts as a positive regulator of receptor function. With the right combination of receptor and cochaperone expression plasmids, reporter plasmid, and ligand, the assay protocol described here could be used to functionally characterize a wide variety of nuclear receptor-cochaperone interactions. In addition to the functional characterization of receptor regulatory proteins, a modified version of this assay is currently being used to screen compound libraries for selective FKBP52 inhibitors that represent attractive therapeutic candidates for the treatment of steroid hormone receptor-associated diseases.
