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]. * **UniProt Summary**: 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. {ECO:0000269|PubMed:15619630}. |7tm 1| |taste receptor activity| |fatty acid binding| |detection of chemical stimulus involved in sensory perception of taste| |endocytic vesicle| |sensory perception of taste| |negative regulation of cytokine secretion| |hormone secretion| |regulation of glucose transmembrane transport| |hormone transport| |positive regulation of cold-induced thermogenesis| |fat cell differentiation| |negative regulation of protein secretion| |negative regulation of inflammatory response| |negative regulation of peptide secretion| |regulation of cold-induced thermogenesis| |signal release| |negative regulation of protein transport| |negative regulation of establishment of protein localization| |negative regulation of secretion by cell| |regulation of cytokine secretion| |negative regulation of defense response| |positive regulation of ERK1 and ERK2 cascade| |negative regulation of secretion| |negative regulation of cytokine production| |regulation of ERK1 and ERK2 cascade| |regulation of inflammatory response| |negative regulation of response to external stimulus| |regulation of protein secretion| |negative regulation of transport| |detection of chemical stimulus involved in sensory perception| |regulation of peptide secretion| |detection of chemical stimulus| |regulation of hormone levels| |sensory perception of chemical stimulus| |positive regulation of MAPK cascade| |detection of stimulus involved in sensory perception| |regulation of transmembrane transport| |detection of stimulus| |regulation of cytokine production| |regulation of protein transport| |G protein-coupled receptor activity| |regulation of peptide transport| |regulation of establishment of protein localization| |regulation of secretion by cell| |regulation of MAPK cascade| |regulation of defense response| |regulation of secretion| |negative regulation of apoptotic process| |negative regulation of programmed cell death| |sensory perception| |negative regulation of cell death| |secretion by cell| |positive regulation of protein phosphorylation| |positive regulation of intracellular signal transduction| |regulation of protein localization| |export from cell| |positive regulation of phosphorylation| |regulation of response to external stimulus| |cell-cell signaling| |secretion| |positive regulation of phosphorus metabolic process| |positive regulation of phosphate metabolic process| |negative regulation of multicellular organismal process| |positive regulation of protein modification process| |G protein-coupled receptor signaling pathway| |nervous system process| |integral component of plasma membrane| |regulation of protein phosphorylation| |regulation of response to stress| |regulation of apoptotic process| |regulation of programmed cell death| |regulation of phosphorylation| |positive regulation of cellular protein metabolic process| |negative regulation of response to stimulus| |positive regulation of signal transduction| |regulation of cell death| |positive regulation of protein metabolic process| |positive regulation of multicellular organismal process| |regulation of phosphate metabolic process| |regulation of phosphorus metabolic process| |positive regulation of cell communication| |positive regulation of signaling| |regulation of intracellular signal transduction| |regulation of protein modification process| |regulation of transport| |system process| \\ === CRISPR Data === No hits were found.
