Enables arachidonate 12(S)-lipoxygenase activity and arachidonate 15-lipoxygenase activity. Involved in several processes, including fatty acid metabolic process; phosphatidylethanolamine biosynthetic process; and positive regulation of actin filament polymerization. Acts upstream of or within bone mineralization. Located in cytosol and plasma membrane. Is expressed in several structures, including alimentary system; liver; nose; peritoneal fluid; and respiratory system. Orthologous to human ALOX15 (arachidonate 15-lipoxygenase).
