1 Here, we examined the activity of human Hsp90alpha and Hsp90beta in a purified five-protein chaperone machinery that assembles glucocorticoid receptor (GR) Hsp90 heterocomplexes to generate high-affinity steroid-binding activity.

3 We showed that the phosphomimetic mutant Hsp90alpha T5/7D has the same intrinsic chaperone activity as wild-type human Hsp90alpha in activation of GR steroid-binding activity by the five-protein machinery, supporting the conclusion that T5/7 phosphorylation does not affect Hsp90alpha chaperone activity.
