What is the Meaning of FKBP5?

FKBP5 is a gene that encodes the FK506-binding protein 51, a crucial co-chaperone protein involved in regulating the sensitivity of the glucocorticoid receptor (GR) to the stress hormone cortisol. Polymorphisms in the FKBP5 gene are frequently studied in endocrinology and psychiatry because they can significantly modulate an individual's stress response and hormonal feedback loop. Understanding this genetic factor is important for personalized approaches to stress management and mood disorders.

What is the Origin of FKBP5?

The acronym FKBP5 is derived from the protein's ability to bind to the immunosuppressant drug FK506 (Tacrolimus) and its size classification as a member of the immunophilin family. The number '5' denotes its specific family member. Its physiological role in stress response became clearer as researchers investigated the molecular machinery governing glucocorticoid action.

What is the Mechanism of FKBP5?

FKBP5 acts as a molecular brake on the glucocorticoid receptor complex; when bound to the receptor, it decreases the receptor's affinity for cortisol and prevents its translocation into the nucleus. Stress-induced cortisol release triggers the dissociation of FKBP5 from the receptor, which then allows the GR to enter the nucleus and activate target genes. Genetic variations in FKBP5 can lead to a chronically less sensitive GR, resulting in impaired negative feedback and sustained activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis.
