Background: Cochaperones are important for the folding and activation of steroid hormone receptors. Results: The androgen receptor-associated cochaperone SGTA binds both Hsp70 and Hsp90 and regulates progesterone and glucocorticoid receptors. Conclusion: SGTA is a receptor-specific cochaperone that regulates distinct steps in the receptor chaperoning cycle. Significance: SGTA is a relevant factor in diseases that depend on androgens, progestins and/or glucocorticoids.
