Identification of membrane-type receptor for bile acids (M-BAR)

Bile acids play an essential role in the solubilization and absorption of dietary fat and lipid-soluble vitamins. Bile acids also modulate the transcription of various genes for enzymes and transport proteins for their own and cholesterol homeostasis through binding to nuclear receptors. Here we report a novel category of bile acid receptor, a membrane-type G protein-coupled receptor (GPCR), BG37. Bile acids induced rapid and dose-dependent...
