Enables arachidonate-CoA ligase activity. Involved in several processes, including organophosphate biosynthetic process; positive regulation of lipid metabolic process; and positive regulation of long-chain fatty acid import across plasma membrane. Located in mitochondrion. Colocalizes with endoplasmic reticulum. Orthologous to human ACSL5 (acyl-CoA synthetase long chain family member 5). [provided by Alliance of Genome Resources, Apr 2022]
