The G protein-coupled bile acid receptor 1 (GPBAR1) also known as G-protein coupled receptor 19 (GPCR19), membrane-type receptor for bile acids (M-BAR) or Takeda G protein-coupled receptor 5 (TGR5) is a protein that in humans is encoded by the GPBAR1 gene. Activated by bile acids, these receptors play a crucial role in metabolic regulation, including insulin secretion and energy balance, and are found in the gastrointestinal tract as well as other tissues throughout the body.
