Summaries for FFAR1 Gene

Entrez Gene Summary for FFAR1 Gene

  • This gene encodes a member of the GP40 family of G protein-coupled receptors that are clustered together on chromosome 19. The encoded protein is a receptor for medium and long chain free fatty acids and may be involved in the metabolic regulation of insulin secretion. Polymorphisms in this gene may be associated with type 2 diabetes. [provided by RefSeq, Apr 2009]

GeneCards Summary for FFAR1 Gene

FFAR1 (Free Fatty Acid Receptor 1) is a Protein Coding gene, and is affiliated with the lncRNA class. Among its related pathways are Insulin secretion and Peptide ligand-binding receptors. GO annotations related to this gene include G-protein coupled receptor activity and guanyl-nucleotide exchange factor activity. An important paralog of this gene is GPR132.

UniProtKB/Swiss-Prot for FFAR1 Gene

  • 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.

Tocris Summary for FFAR1 Gene

  • Free Fatty Acid (FFA) receptors are a group of Gq/11 protein-coupled receptors that are currently divided into FFA1, FFA2 and FFA3 subtypes. FFA receptors are concentrated in the pancreatic islet cells (particularly FFA1) and in the brain.

Function for FFAR1 Gene

Molecular function for FFAR1 Gene

UniProtKB/Swiss-Prot EnzymeRegulation:
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).
UniProtKB/Swiss-Prot 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).
