Formation of Hap46/BAG-1M complexes with several transcription factors. Transcription factors, as indicated, were synthesized as radiolabeled proteins by in vitro transcription/translation from recombinant constructs. They were then incubated in the presence of hsc70, contained in the reticulocyte lysate, with Sepharose matrices to which either Hap46/BAG-1M (lanes 1) or deletion variant Hap46/BAG-1MΔC47 (lanes 2) had been attached. After extensive washing, retained proteins were eluted and analyzed by electrophoresis in SDS-containing polyacrylamide gels and radioautography. Glucocorticoid receptor (GR); Estrogen receptor (ER).
