• PubMed Abstract: 
  

Steroid hormone receptors are key components of mammalian stress and sex hormone systems. Many of them rely on the Hsp90 chaperone system for full function and are further fine-tuned by Hsp90-associated peptidyl-prolyl isomerases such as FK506-binding proteins 51 and 52. FK506-binding protein 51 (FKBP51) has been shown to reduce glucocorticoid receptor signalling and has been genetically associated with human stress resilience and with numerous psychiatric disorders. The peptidyl-prolyl isomerase domain of FKBP51 contains a high-affinity binding site for the natural products FK506 and rapamycin and has further been shown to convey most of the inhibitory activity on the glucocorticoid receptor. FKBP51 has therefore become a prime new target for the treatment of stress-related affective disorders that could be amenable to structure-based drug design. Here, a series of high-resolution structures of the peptidyl-prolyl isomerase domain of FKBP51 as well as a cocrystal structure with the prototypic ligand FK506 are described. These structures provide a detailed picture of the drug-binding domain of FKBP51 and the molecular binding mode of its ligand as a starting point for the rational design of improved inhibitors.
