Summary: This gene belongs to the lipoxygenase (LOX) gene family whose members encode enzymes that catalyze the addition of molecular oxygen to polyunsaturated fatty acids (PUFAs) to yield fatty acid hydroperoxides. The encoded enzyme preferentially metabolizes arachidonic acid to yield 8-hydroxyeicosatetraenoic acid (8-HETE), while metabolizing linoleic acid less efficiently. The gene may also function as a tumor suppressor. This gene is located in a cluster of related genes that spans approximately 75 kilobases on chromosome 11. [provided by RefSeq, Jan 2013]

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.
