Protein Information (annotations from UniProt)

Database IDHIV0003569
UniProt IDQ9ULC5
Primary gene name(s)ACSL5
Synonym gene name(s)ACS5, FACL5
Protein nameLong-chain-fatty-acid--CoA ligase 5
Protein functionAcyl-CoA synthetases, ACSL activate long-chain fatty acids for both synthesis of cellular lipids, and degradation via beta-oxidation. ACSL5 may activate fatty acids from exogenous sources for the synthesis of triacylglycerol destined for intracellular storage, By similarity. Utilizes a wide range of saturated fatty acids with a preference for C16-C18 unsaturated fatty acids, By similarity. It was suggested that it may also stimulate fatty acid oxidation, By similarity. At the villus tip of the crypt-villus axis of the small intestine may sensitize epithelial cells to apoptosis specifically triggered by the death ligand TRAIL. May have a role in the survival of glioma cells. {ECO:0000250, ECO:0000269|PubMed:17681178, ECO:0000269|PubMed:18806831, ECO:0000269|PubMed:19459852}.
