Enables arachidonate-CoA ligase activity. Involved in several processes, including brain development; fatty acid metabolic process; and response to nutrient. Predicted to be located in Golgi apparatus and perinuclear region of cytoplasm. Predicted to be active in endoplasmic reticulum; lipid droplet; and plasma membrane. Human ortholog(s) of this gene implicated in asthma; breast cancer; and prostate cancer. Orthologous to human ACSL3 (acyl-CoA synthetase long chain family member 3).
