Enables N,N-dimethylaniline monooxygenase activity; NADP binding activity; and amino acid binding activity. Involved in xenobiotic metabolic process. Located in intracellular membrane-bounded organelle. Human ortholog(s) of this gene implicated in hypertension; inherited metabolic disorder; and trimethylaminuria. Orthologous to human FMO3 (flavin containing dimethylaniline monoxygenase 3). [provided by Alliance of Genome Resources, Apr 2022]
