Corticotropin-releasing hormone is a peptide hormone involved in the stress response. It is a releasing hormone that belongs to corticotropin-releasing factor family. In humans, it is encoded by the CRH gene. Its main function is the stimulation of the pituitary synthesis of ACTH, as part of the HPA Axis. Corticotropin-releasing hormone is a 41-amino acid peptide derived from a 196-amino acid preprohormone. CRH is secreted by the paraventricular nucleus of the hypothalamus in response to stress.
