Enables alkane 1-monooxygenase activity; arachidonic acid binding activity; and arachidonic acid monooxygenase activity. Involved in several processes, including fatty acid metabolic process; icosanoid biosynthetic process; and response to hormone. Located in intracellular membrane-bounded organelle. Biomarker of autosomal recessive polycystic kidney disease. Human ortholog(s) of this gene implicated in hypertension. Orthologous to human CYP4A11 (cytochrome P450 family 4 subfamily A member 11) and CYP4A22 (cytochrome P450 family 4 subfamily A member 22). [provided by Alliance of Genome Resources, Apr 2022]
