Enables arachidonic acid monooxygenase activity; heme binding activity; and leukotriene-B4 20-monooxygenase activity. Involved in leukotriene B4 catabolic process; omega-hydroxylase P450 pathway; and prostaglandin catabolic process. Predicted to be located in endoplasmic reticulum membrane. Predicted to be integral component of membrane. Predicted to be active in intracellular membrane-bounded organelle. Orthologous to human CYP4F11 (cytochrome P450 family 4 subfamily F member 11) and CYP4F2 (cytochrome P450 family 4 subfamily F member 2). [provided by Alliance of Genome Resources, Apr 2022]
