An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

A proteomic investigation of ligand-dependent HSP90 complexes reveals CHORDC1 as a novel ADP-dependent HSP90-interacting protein.

Gano JJ, Simon JA

Structural studies of the chaperone HSP90 have revealed that nucleotide and drug ligands induce several distinct conformational states; however, little is known how these conformations affect interactions with co-chaperones and client proteins. Here we use tandem affinity purification and LC-MS/MS to investigate the proteome-wide effects of ATP, ADP, and geldanamycin on the constituents of the human HSP90 interactome. We identified ...
