Free fatty acid receptor 2 (FFA2) is a G-protein coupled receptor encoded by the FFAR2 gene.[4]


Expression[edit]

FFAR2 mRNA is expressed in adipose tissue, pancreas, spleen, lymph nodes, bone marrow, and peripheral blood mononuclear cells.[5][6] FFAR2 transcription is regulated by the XBP1 transcription factor which binds to the core promoter.[7]

Function[edit]

Mouse studies utilizing Ffar2 gene deletions have implicated the receptor in the regulation of energy metabolism and immune responses.[8] However, discrepancies between the pathways activated by FFAR2 agonists in human cells and the equivalent murine counterparts have been observed.[9][10][11]
