Long-chain-fatty-acid—CoA ligase 4 is an enzyme that in humans is encoded by the ACSL4 gene.The protein encoded by this gene is an isozyme of the long-chain fatty-acid-coenzyme A ligase family. Although differing in substrate specificity subcellular localization and tissue distribution all isozymes of this family convert free long-chain fatty acids into fatty acyl-CoA esters and thereby play a key role in lipid biosynthesis and fatty acid degradation.
