We built a homogeneous bead-based assay to study chaperone-cochaperone interactions. Using this technique, we screen small molecules inhibiting interactions between Hsp90 and FKDP51 or FKBP52 and identify potent and selective inhibitors. This high

This protocol presents a technique for probing protein-protein interactions using glutathione-linked donor beads with GST-fused TPR-motif co-chaperones and acceptor beads coupled with an Hsp90-derived peptide. We have used this technique to screen small molecules to disrupt Hsp90-FKBP51 or Hsp90-FKBP52 interactions and identified potent and selective Hsp90-FKBP51 interaction inhibitors.
