Steroid receptors are recovered from hormone-free cells in multiprotein complexes containing hsp90, p23, an immunophilin, and often some hsp70. The immunophilin, which can be of the FK506- or(More)
We previously identified a protein-serine phosphatase designated PP5, based on the binding of its tetratricopeptide repeat (TPR) domain to the atrial natriuretic peptide receptor (Chinkers, M. (1994)(More)
Rabbit reticulocyte lysate contains a multiprotein chaperone system that assembles steroid receptors into a complex with hsp90. The glucocorticoid receptor (GR) is bound to hsp90 via its hormone(More)
We have shown recently that the immunophilins CyP-40 and FKBP52/hsp56 bind to a common site on hsp90 and that they exist in separate heterocomplexes with the glucocorticoid receptor (GR).(More)
