UniProt functional annotation for O14842

UniProt code: O14842.

Organism: Homo sapiens (Human).
Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.
 
Function: G-protein coupled receptor for medium and long chain saturated and unsaturated fatty acids that plays an important role in glucose homeostasis. Fatty acid binding increases glucose-stimulated insulin secretion, and may also enhance the secretion of glucagon-like peptide 1 (GLP-1). May also play a role in bone homeostasis; receptor signaling activates pathways that inhibit osteoclast differentiation (By similarity). Ligand binding leads to a conformation change that triggers signaling via G-proteins that activate phospholipase C, leading to an increase of the intracellular calcium concentration. Seems to act through a G(q) and G(i)-mediated pathway. Mediates the anti-inflammatory effects of omega-3 polyunsaturated fatty acids (PUFAs) via inhibition of NLRP3 inflammasome activation. {ECO:0000250|UniProtKB:Q76JU9, ECO:0000269|PubMed:12496284, ECO:0000269|PubMed:17699519, ECO:0000269|PubMed:23809162, ECO:0000269|PubMed:24130766, ECO:0000269|PubMed:24742677}.
 
Activity regulation: The receptor is strongly activated by gamma- linolenic acid, while myristate gives a lower response. It is also activated by phytanic acid and pristanic acid (PubMed:21570468). Is also activated by synthetic agonists, such as TAK-875 (fasiglifam); this compound is a partial agonist and potentiates the activity of the endogenous ligand gamma-linolenic acid (PubMed:24130766). {ECO:0000269|PubMed:21570468, ECO:0000269|PubMed:24130766}.
Subcellular location: Cell membrane {ECO:0000269|PubMed:17699519, ECO:0000269|PubMed:25043059}; Multi-pass membrane protein {ECO:0000269|PubMed:25043059}.
Tissue specificity: Detected in brain and pancreas. Detected in pancreatic beta cells. {ECO:0000269|PubMed:12496284, ECO:0000269|PubMed:16289108}.
Similarity: Belongs to the G-protein coupled receptor 1 family. {ECO:0000255|PROSITE-ProRule:PRU00521}.
