Enables several functions, including glucocorticoid receptor binding activity; heat shock protein binding activity; and purine ribonucleoside triphosphate binding activity. Acts upstream of or within several processes, including androgen receptor signaling pathway; embryo implantation; and steroid hormone receptor complex assembly. Located in nucleus. Is expressed in pancreas epithelium. Used to study androgen insensitivity syndrome. Orthologous to human FKBP4 (FKBP prolyl isomerase 4). [provided by Alliance of Genome Resources, Apr 2022]
