Biological importance of basal activity of appetite suppressor
The most frequent genetic cause
of obesity in humans is melanocortin-4 receptor (MC4R) mutations. MC4R has an effect on appetite: when MC4R is activated by its ligand amelanocyte-stimulat-ing hormone (a-MHC) appetite is suppressed. When its activity is suppressed by its ligand ago...
