Summary: Enables stearoyl-CoA 9-desaturase activity. Predicted to be involved in arachidonate metabolite production involved in inflammatory response; lipid metabolic process; and positive regulation of cellular response to oxidative stress. Predicted to be located in membrane. Is expressed in several structures, including adrenal gland; genitourinary system; nervous system; and retina. Orthologous to human FADS2 (fatty acid desaturase 2). [provided by Alliance of Genome Resources, Dec 2024]

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.
