Data Sheet

Background: GPR43, or free fatty acid receptor 2 (FFAR2), encodes a deduced 330- amino acid protein with 7 transmembrane domains. GPR43 is expressed by enteroendocrine L cells containing peptide YY in the large intestine, adipocytes, and peripheral blood mononuclear cells. The GPR43 receptor binds short-chain fatty acids composed of less than 5 carbon atoms. Many short-chain fatty acids are produced by gut bacteria during dietary fiber fermentation. This ligand specificity provides a molecular link between diet, gastrointestinal bacterial metabolism, and immune and inflammatory responses. The importance of GPR43 in inflammation, glucose and lipid homeostasis, and adiposity demonstrate its potential as a therapeutic target for type 2 diabetes, obesity, and ulcerative colitis.
