Enables arachidonate-CoA ligase activity; oleoyl-CoA ligase activity; and phytanate-CoA ligase activity. Involved in several processes, including fatty acid metabolic process; long-chain fatty-acyl-CoA biosynthetic process; and positive regulation of long-chain fatty acid import across plasma membrane. Located in bounding membrane of organelle; endoplasmic reticulum; and plasma membrane. Biomarker of obesity. Orthologous to human ACSL1 (acyl-CoA synthetase long chain family member 1).
