It is a widely accepted concept that G-protein-coupled receptors (GPCRs) are able to form homo- and heterodimers. The physiological relevance of these interactions is of utmost importance.Recently, we demonstrated that due to co-expression of two key players of hypothalamic body weight regulation, the melanocortin 3 receptor (MC3R) and ghrelin receptor (GHSR), signalling of the MC3R is enhanced (hyperstimulation) as compared to activation of MC3R alone. ...
