Background: FFAR2/GPR43

Human Free fatty acid receptor 2 (FFA2, FFAR2, GPCR43 or GPR43) is a 330 aminoacids G-protein coupled receptor encoded by the FFAR2 gene. G-protein-coupled receptors (GPCRs) are seven-trans-membrane (7TM) receptors that mediate cellular responses to the majority of hormones and neurotransmitters and are common targets for drug discovery. Human GPR43/FFA2 is present in a large variety of tissues, including adipose tissue, inflammatory cells, and gastrointestinal (GI) tract and is activated by short-chain fatty acids (SCFAs). Studies on knockout mice have identified Free Fatty Acid Receptor 2 (FFAR2 or GPR43) as a critical gene in the prevention of obesity, colitis, asthma and arthritis.
