Predicted to enable heme binding activity and heme oxygenase (decyclizing) activity. Predicted to be involved in several processes, including iron ion homeostasis; porphyrin-containing compound catabolic process; and response to hypoxia. Predicted to be located in plasma membrane. Is expressed in several structures, including alimentary system; integumental system; nervous system; respiratory system; and sensory organ. Orthologous to human HMOX2 (heme oxygenase 2).
