Summary: Enables acyl-CoA delta5-desaturase activity. Predicted to be involved in arachidonate metabolic process; cellular response to starvation; and unsaturated fatty acid biosynthetic process. Predicted to act upstream of or within long-chain fatty acid biosynthetic process. Predicted to be located in endoplasmic reticulum membrane and mitochondrion. Is expressed in several structures, including alimentary system; eye; genitourinary system; nervous system; and respiratory system. Orthologous to human FADS1 (fatty acid desaturase 1).

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.
