Summaries for FFAR4 Gene

Entrez Gene Summary for FFAR4 Gene

  • This gene encodes a G protein-coupled receptor (GPR) which belongs to the rhodopsin family of GPRs. The encoded protein functions as a receptor for free fatty acids, including omega-3, and participates in suppressing anti-inflammatory responses and insulin sensitizing. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2012]

GeneCards Summary for FFAR4 Gene

FFAR4 (Free Fatty Acid Receptor 4) is a Protein Coding gene. Diseases associated with FFAR4 include Obesity. Among its related pathways are Peptide ligand-binding receptors and Signaling by GPCR. GO annotations related to this gene include G-protein coupled receptor activity and taste receptor activity.

UniProtKB/Swiss-Prot for FFAR4 Gene

  • 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.

    Quaternary structure:
    • Interacts with ARRB2 following docosahexaenoic acid (DHA) stimulation.
    Miscellaneous:
    • It has been shown that FFA alpha-linolenic acid stimulates secretion of glucagon-like peptide 1 (GLP-1) from the gastro-intestinal tract (PubMed:15619630). However, this ligand is an agonist of both FFAR4 and FFAR1 and the latter has been shown to mediate GLP-1 release too (PubMed:18519800). So the precise role of FFAR4 in mediating needs to be confirmed.
