GPR45 modulates Gα s at primary cilia of the paraventricular hypothalamus to control food intake

Abstract excerpt

The melanocortin system centrally regulates energy homeostasis, with key components such as melanocortin-4 receptor (MC4R) and adenylyl cyclase 3 (ADCY3) in neuronal primary cilia. Mutations in MC4R and ADCY3 as well as ciliary dysfunction lead to obesity, but how melanocortin signaling works in cilia remains unclear. Using mouse random germline mutagenesis, we identified two missense mutations in G...
