ACSL1
| View/Edit Human | View/Edit Mouse |
Long-chain-fatty-acid—CoA ligase 1 is an enzyme that in humans is encoded by the ACSL1 gene.[3][4][5]
Structure
Gene
The ACSL4 gene is located on the 4th chromosome, with its specific location being 4q35.1. The gene contains 28 exons.[5]
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.[5]
In melanocytic cells ACSL1 gene expression may be regulated by MITF.[6]
Function
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.[5] Several transcript variants encoding different isoforms have been found for this gene. This specific protein is most commonly found in mitochondria and peroxisomes.[7]
Clinical significance
ACSL1 was shown to be involved in nonspecific mental retardation and fatty-acid metabolism.[8] Since the ACSL4 gene is highly expressed in brain, where it encodes a brain specific isoform, an ASCL1 mutation may be an efficient diagnostic tool in mentally retarded males.[9]
Interactions
ACSL1 expression is regulated by SHP2 activity.[10] Additionally, ACSL4 interacts with ACSL3, APP, DSE, ELAVL1, HECW2, MINOS1, PARK2, SPG20, SUMO2, TP53, TUBGCP3, UBC, UBD, and YWHAQ.[5]
