Enables arachidonate-CoA ligase activity and protein homodimerization activity. Involved in several processes, including organophosphate biosynthetic process; positive regulation of long-chain fatty acid import across plasma membrane; and triglyceride biosynthetic process. Located in nucleus. Human ortholog(s) of this gene implicated in acute myeloid leukemia and leukemia. Orthologous to human ACSL6 (acyl-CoA synthetase long chain family member 6).
