    Summary
    Enables acyl-CoA delta5-desaturase activity. Involved in several processes, including response to insulin; response to vitamin A; and unsaturated fatty acid metabolic process. Predicted to be located in endoplasmic reticulum membrane and mitochondrion. Biomarker of congestive heart failure; hypertension; and obesity. 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.
