WebAug 15, 2024 · Pro-opiomelanocortin (POMC) gives rise to ACTH and melanocyte-stimulating hormone (MSH). This association is clinically important for Addison disease. ACTH receptors are in the adrenal cortex, in particular, the zona fasciculata and zona reticularis. The receptors are G protein-coupled receptors, thus stimulating adenylyl cyclase. WebAug 19, 2024 · Introduction. Adrenocorticotropic hormone (ACTH) was first described in 1933, and after nearly 20 years, it was demonstrated that this polypeptide hormone stimulates adrenocortical activity (1–3).ACTH is exclusively produced from prohormone proopiomelanocortin (POMC), which is majorly synthetized in the corticotroph and …
