Enables acetyl-CoA carboxylase activity. Involved in acetyl-CoA metabolic process; fatty acid biosynthetic process; and protein homotetramerization. Acts upstream of or within several processes, including cellular response to prostaglandin E stimulus; lipid homeostasis; and tissue homeostasis. Located in cytosol. Is expressed in several structures, including alimentary system; integumental system; nervous system; respiratory system; and sensory organ. Orthologous to human ACACA (acetyl-CoA carboxylase alpha).
