The FKBP51 Glucocorticoid Receptor Co-Chaperone: Regulation, Function, and Implications in Health and Disease
- BiologyInternational journal of molecular sciences
- 2017
An update on the role of the different co-chaperones of Hsp70 and Hsp90 in the regulation of GR function is provided and the evidence portraying FKBP51 as a scaffolding protein organizing protein complexes rather than a chaperone contributing to the folding of individual proteins is collated.

Hsp90-Mediated Maturation of Kinases andNuclear Steroid Hormone Receptors:A Dissertation
- Biology
- 2011
It is found that ATP binding and hydrolysis by Hsp90 are both required for the efficient maturation of the glucocorticoid hormone receptor (GR) and vsrc confirming the critical role of ATPHydrolysis in the m maturity of steroid hormone receptors and kinases in vivo.
Role of molecular chaperones and TPR-domain proteins in the cytoplasmic transport of steroid receptors and their passage through the nuclear pore
- BiologyNucleus
- 2010
Experimental evidence is consistent with a model where the chaperone machinery is required for the retrotransport of the receptor through the cytoplasm and also facilitates the passage through the nuclear pore.
From hatching to dispatching: the multiple cellular roles of the Hsp70 molecular chaperone machinery.
- BiologyJournal of molecular endocrinology

It is proposed that an increased Hsp90/GR ratio influences the responsiveness to ligand at a step that is after receptor activation, and this increased ratio may be of pathophysiological relevance in the different circumstances that lead to an elevated level of nuclear HSp90.
