Background: GPR43, or free fatty acid receptor 2 (FFAR2), encodes a deduced 330- amino acid protein with 7 transmembrane domains. GPR43 is expressed by white adipose tissue and immune tissue of adult mice. The receptor binding of short-chain fatty acids potentially provides an intestine molecular link between diet, gastrointestinal bacterial metabolism, and immune and inflammatory responses.
Application: Functional assays
