O3FAR1 / GPR120

free fatty acid receptor 4

Receptor for medium and long-chain free fatty acids (FFAs). Signals via a G(q)/G(11)-coupled pathway. Acts as a receptor for omega-3 fatty acids and mediates robust anti-inflammatory effects, particularly in macrophages and fat cells. The anti-inflammatory effects involve inhibition of TAK1 through a beta-arrestin 2 (ARRB2)/TAB1-dependent effect, but independent of the G(q)/G(11)-coupled pathway. Mediates potent insulin sensitizing and antidiabetic effects by repressing macrophage-induced tissue inflammation. May mediate the taste of fatty acids. Mediates FFA-induced inhibition of apoptosis in enteroendocrine cells. May play a role in the regulation of adipocyte development and differentiation.

Gene Name: free fatty acid receptor 4
Family/Subfamily: GPCR , Fatty acid
Synonyms: FFAR4, Free fatty acid receptor 4, GT01, GPR129, GPR120, O3FAR1, PGR4, BMIQ10
Target Sequences: NM_181745 NP_859529.2 Q5NUL3
