Pomc synthese
WebAlthough the main POMC product in the pars distalis is ACTH, in the pars intermedia it is α-MSH. Under physiologic conditions, the melanotrophs are under the suppressive control of hypothalamic periventricular neurons that tonically release dopamine (activating dopaminergic D2–type receptors) to inhibit POMC synthesis, processing, and secretion.
