Peptidyl-prolyl cis-trans isomerase FKBP5 (FKBP5)

Immunophilin protein with PPIase and co-chaperone actions. Part of unligated steroid receptors heterocomplexes through interaction with heat-shock protein 90 (HSP90).

Plays a role in the intracellular trafficking of heterooligomeric kinds of steroid hormone receptors maintaining the complex into the cytoplasm when unliganded. .
