26518871 Although both agonist and antagonist ligands contain negatively charged carboxylates that interact with two key positively charged arginine residues in transmembrane domains V and VII of FFA2, there are clear differences in how these interactions occur.
26075576 FFAR2 signaling occurs by divergent G protein pathways.
26023106 GPR3 agonism potentiates insulin secretion in isolated islets.
25633224 GPR43 expression is reduced in monocytes upon siRNA-knockdown of XBP1, while A549 cells overexpressing XBP1 displayed elevated GPR43 levels.
25581519 FFAR2 is expressed in pancreatic beta cells and mediates an inhibition of insulin secretion by coupling to Gi-type G proteins.
25298143 FFAR2 is a potential therapeutic target of T1 diabetes, representing a link between immune response and glucose homeostasis.
24458110 [review] In vivo and in vitro studies suggest that short-chain fatty acid receptors (SCFAs) stimulate gut hormone secretion; therefore, the SCFA-FFA signal is likely to be important for gut physiological functions.
23985900 GPR43 modulates NF-kappaB activity via beta-arrestin 2.
23066016 Extracellular ionic locks determine variation in constitutive activity and ligand potency between species orthologs of the free fatty acid receptors FFA2 and FFA3
22919070 Data indicate that a single mutation in human FFA2 of C4.57G resulted in a human FFA2 receptor with ligand selectivity similar to the bovine receptor.
