Adrenocorticotropic hormone stimulates the adrenal cortex. More specifically，it stimulates secretion of glucocorticoids such as cortisol，and has little control over secretion of aldosterone，the other major steroid hormone from the adrenal cortex. Stimulates secretion of adrenal corticosteroids and induces growth of adrenal cortex. ACTH also called Tetracosactide directly activates G-proteins. A stimulator of adenylate cyclase and cAMP formation，its molecular weight is 2.9335 kDa.
