Free fatty acid receptor 2 (FFAR2) is a G-protein coupled receptor encoded by the FFAR2 gene.[5]

Expression

FFAR2 mRNA is expressed in adipose tissue, pancreas, spleen, lymph nodes, bone marrow, and peripheral blood mononuclear cells.[6][7] FFAR2 transcription is regulated by the XBP1 transcription factor which binds to the core promoter.[8]

Function

Mouse studies utilizing Ffar2 gene deletions have implicated the receptor in the regulation of energy metabolism and immune responses.[9] However, discrepancies between the pathways activated by FFAR2 agonists in human cells and the equivalent murine counterparts have been observed.[10][11][12]

Heteromerization

FFAR2 may interact with FFAR3 to form a FFAR2-FFAR3 receptor heteromer with signalling that is distinct from the parent homomers.[13]
