Descripción
The mineralocorticoid receptor (MR) forms oligomers with the heat-shock protein 90 (Hsp90) -based heterocomplex, which contains tetratricopeptide repeat (TPR) domain immunophilins (IMMs). Here we investigated the unknown biological role of IMMs in the MR·Hsp90 complex. Upon hormone binding, FKBP52 was greatly recruited to MR·Hsp90 complexes along with dynein motors, whereas FKBP51 was dissociated. Importantly, the Hsp90 inhibitor geldanamycin impaired the retrograde transport of MR, suggesting that the Hsp90·IMM·dynein molecular machinery is required for MR movement. To elucidate the mechanism of action of MR, the synthetic ligand 11,19-oxidoprogesterone was used as a tool. This steroid showed equivalent agonistic potency to natural agonists and was able to potentiate their mineralocorticoid action. Importantly, aldosterone binding recruited greater amounts of FKBP52 and dynein than 11,19-oxidoprogesterone binding to MR. Interestingly, 11,19-oxidoprogesterone binding also favored the selective recruitment of the IMM-like Ser/Thr phosphatase PP5. Each hormone/MR complex yielded different proteolytic peptide patterns, suggesting that MR acquires different conformations upon steroid binding. Also, hormone/MR complexes showed different nuclear translocation rates and subnuclear redistribution. All these observations may be related to the selective swapping of associated factors. We conclude that (a) the Hsp90·FKBP52·dyenin complex may be responsible for the retrotransport of MR; (b) a differential recruitment of TPR proteins such as FKBP51, FKBP52, and PP5 takes place during the early steps of hormone-dependent activation of the receptor; (c) importantly, this swapping of TPR proteins depends on the nature of the ligand; and (d) inasmuch as FKBP51 also showed an inhibitory effect on MR-dependent transcription, it should be dissociated from the MR·Hsp90 complex to positively regulate the mineralocorticoid effect.
