• ACTH is an important component of the hypothalamic-pituitary-adrenal axis and is often produced in response to biological stress (along with its precursor corticotropin-releasing hormone from the hypothalamus). (wikipedia.org)
  • POMC, ACTH and β-lipotropin are secreted from corticotropic cells in the anterior lobe (or adenohypophysis) of the pituitary gland in response to the hormone corticotropin-releasing hormone (CRH) released by the hypothalamus. (wikipedia.org)
  • ACTH consists of 39 amino acids, the first 13 of which (counting from the N-terminus) may be cleaved to form α-melanocyte-stimulating hormone (α-MSH) (this common structure is responsible for excessively tanned skin in Addison's disease). (wikipedia.org)
