Protein-coding gene in the species Homo sapiens
G protein-coupled receptor 119 also known as GPR119 is a G protein-coupled receptor that in humans is encoded by the GPR119 gene.[5]
GPR119, along with GPR55 and GPR18, have been implicated as novel cannabinoid receptors.[6][7][8]
Pharmacology
GPR119 is expressed predominantly in the pancreas and gastrointestinal tract in rodents and humans, as well as in the brain in rodents.[9] Activation of the receptor has been shown to cause a reduction in food intake and body weight gain in rats.[9] GPR119 has also been shown to regulate incretin and insulin hormone secretion.[10][11][12] As a result, new drugs acting on the receptor have been suggested as novel treatments for obesity and diabetes.[9][11][13]
Ligands
A number of endogenous and synthetic ligands for this receptor have been identified:[14][15][16]
