ACTH

Adrenocorticotropic hormone (corticotropin); 39-aa peptide cleaved from POMC by pituitary corticotrophs. CRH → ACTH → cortisol is the HPA axis effector chain. MC2R/Gs/cAMP/PKA activates adrenal steroidogenesis; circadian peak just before waking; negative feedback via GR.

Also known as: ACTH, corticotropin, adrenocorticotropin, adrenocorticotropic hormone, POMC, MC2R, corticotroph, cosyntropin, Synacthen, tetracosactide
