1 Hop binds independently to Hsp90 and to Hsp70 to form a Hsp90.Hop.Hsp70.Hsp40 complex that is sufficient to convert the GR to its steroid binding form, and this four-protein complex will form stable GR.Hsp90 heterocomplexes if p23 is added to the system (Dittmar, K.

4 By carrying out assembly in the presence of radiolabeled steroid to bind to the GR as soon as it is converted to the steroid binding state, we show that the folding change is brought about by only two essential components, Hsp90 and Hsp70, and that Hop, Hsp40, and p23 act as nonessential co-chaperones.
