Mutations in the hypothalamic expressed MC4R gene are the most frequent cause of monogenetic obesity. This Gαs-Protein coupled receptor (GPCR) is activated by endogenous ligands α- and β-MSH and is inhibited by the only known endogenous inverse agonist and antagonist Agouti related peptide (AgRP). Naturally occurring mutations help to understand activation mechanisms of the human MC4R.We previously described a constitutively act...
