Enables arachidonate 15-lipoxygenase activity. Involved in arachidonic acid metabolic process; hepoxilin biosynthetic process; and lipoxygenase pathway. Predicted to be located in several cellular components, including adherens junction; cytosol; and focal adhesion. Predicted to be extrinsic component of membrane. Orthologous to human ALOX15B (arachidonate 15-lipoxygenase type B). [provided by Alliance of Genome Resources, Apr 2022]
