G-protein-independent coupling of MC4R to Kir7.1 in hypothalamic neurons
2015
α-MSH and AgRP, two hypothalamus-derived peptides with opposing actions on the melanocortin-4 receptor (MC4R), modulate neurons driving feeding behaviour; although previous downstream mechanisms of cellular modulation by these peptides have been determined, here α-MSH and AgRP are shown to regulate neural activity by coupling MC4R to Kir7.1 potassium channels and closing or opening them, respectively.
