Adrenocorticotropic Hormone (ACTH): What It Is & Function

WebMay 5, 2024 · MECHANISM OF ACTH ACTION Corticotropin (ACTH) acts by binding to a specific cell-surface receptor, the melanocortin 2 receptor (MC2R) [3]. ACTH upregulates expression of these receptors, thereby increasing the steroidogenic response to further ACTH stimulation [4]. WebThe intent in writing this chapter has been to review selected areas in which several observations by one or more workers have led to the emergence of new concepts in the mechanisms of action of ACTH.

WebJun 13, 2024 · The adrenocorticotropin hormone (ACTH) is synthesized by the corticotroph cells of the anterior pituitary gland. ACTH, a post-translational product of the proopiomelanocortin protein (POMC), is a 39-amino acid peptide, its sequence being highly conserved in mammals.

WebThe influence of ACTH on the adrenal cortex is not limited to stimulation of corticosteroid production; the maintenance of the structure of the adrenal cortex is also dependent upon this hormone. Although this indicates that ACTH is involved in protein synthesis in this organ, again the mechanism of this action of the hormone remains elusive.
