It is probable that this protein is only produced in very small quantity or not at all as the gene coding for it seems to be unable to produce full-length transcripts. H(+) + N,N-dimethylaniline + NADPH + O2 = H2O + N,N-dimethylaniline N-oxide + NADP(+) There are two alleles; one major, FMO6X105 (truncated form) and one minor, FMO6Q105, (shown here) (full-length form similar to the protein found in other mammals) (PubMed:12527699). A nonsense mutation transforms the Gln-105 into a premature stop codon (PubMed:12527699). The truncated protein is catalytically inactive (PubMed:12527699). Belongs to the FMO family. Could be the product of a pseudogene.
