Summary: Enables alkane 1-monooxygenase activity and arachidonate monooxygenase activity. Involved in several processes, including fatty acid metabolic process; icosanoid biosynthetic process; and placenta development. Predicted to be located in extracellular space. Predicted to be active in intracellular membrane-bounded organelle. Biomarker of autosomal recessive polycystic kidney disease and hypertension. Human ortholog(s) of this gene implicated in hypertension. Orthologous to several human genes including CYP4A22 (cytochrome P450 family 4 subfamily A member 22).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
