General annotation (Comments)
| Function | Acyl-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. Ref.8 Ref.10 Ref.11 |
| Catalytic activity | ATP + a long-chain fatty acid + CoA = AMP + diphosphate + an acyl-CoA. |
| Cofactor | Magnesium By similarity. |
| Subcellular location | Mitochondrion. Endoplasmic reticulum. Mitochondrion outer membrane; Single-pass type III membrane protein By similarity. Endoplasmic reticulum membrane; Single-pass type III membrane protein By similarity Ref.8 Ref.11. |
| Sequence similarities | Belongs to the ATP-dependent AMP-binding enzyme family. |
| Biophysicochemical properties | Kinetic parameters: KM=0.11 µM for palmitic acid (isoform 1 at pH 7.5) Ref.8 KM=0.38 µM for palmitic acid (isoform 1 at pH 9.5) KM=0.04 µM for palmitic acid (isoform 3 at pH 7.5) KM=0.15 µM for palmitic acid (isoform 3 at pH 8.5) pH dependence: |
| Sequence caution | The sequence BAA85979.1 differs from that shown. Reason: Erroneous initiation. The sequence BAA86054.1 differs from that shown. Reason: Erroneous gene model prediction. |
Ontologies
Alternative products
| This entry describes 3 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q9ULC5-1) Also known as: ACSL5b; ACSL5-fl; This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Note: Localize in mitochondrion and endoplasmic reticulum. | ||||||
| Isoform 2 (identifier: Q9ULC5-3) Also known as: ACSL5a; The sequence of this isoform differs from the canonical sequence as follows: 1-1: M → MDALKPPCLWRNHERGKKDRDSCGRKNSEPGSPHSLEALRDAAPSQGLNFLLLFTKM | ||||||
| Note: Contains a phosphoserine at position 32. | ||||||
| Isoform 3 (identifier: Q9ULC5-4) Also known as: ACSL5delta20; The sequence of this isoform differs from the canonical sequence as follows: 614-637: Missing. | ||||||
| Note: Localize in mitochondrion and endoplasmic reticulum. |
