MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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]
PHENOTYPE: Homozygotes for a null allele show altered taste responses to fatty acids. Homozygotes for another null allele develop obesity, liver steatosis, and impaired glucose metabolism, adipogenesis and lipogenesis on a high-fat diet. Homozygotes for a third allele show altered islet somatostatin secretion. [provided by MGI curators]
