From NCBI Gene:

This gene encodes a member of the lipoxygenase family of proteins. The encoded enzyme acts on various polyunsaturated fatty acid substrates to generate various bioactive lipid mediators such as eicosanoids, hepoxilins, lipoxins, and other molecules. The encoded enzyme and its reaction products have been shown to regulate inflammation and immunity. Multiple pseudogenes of this gene have been identified in the human genome.

From UniProt:

Non-heme iron-containing dioxygenase that catalyzes the stereo-specific peroxidation of free and esterified polyunsaturated fatty acids generating a spectrum of bioactive lipid mediators (PubMed:23242647, PubMed:25293588, PubMed:1944593, PubMed:17052953, PubMed:8334154, PubMed:24282679). Converts arachidonic acid into 12-hydroperoxyeicosatetraenoic acid/12-HPETE and 15-hydroperoxyeicosatetraenoic acid/15-HPETE (PubMed:1944593, PubMed:17052953, PubMed:8334154, PubMed:24282679). Also converts linoleic acid into 13-hydroperoxyoctadecadienoic acid (PubMed:8334154). Converts epoxy fatty acids to hydroperoxy-epoxides derivatives followed by an intramolecular nucleophilic substitution between hydroperoxy and epoxy moieties leading to the formation of monocyclic endoperoxides (PubMed:25293588). May also act on (12S)-hydroperoxyeicosatetraenoic acid/(12S)-HPETE to produce hepoxilin A3 (By similarity). Probably plays an important role in the immune and inflammatory responses. Through the oxygenation of membrane-bound phosphatidylethanolamine in macrophages may favor clearance of apoptotic cells during inflammation by resident macrophages and prevent an autoimmune response associated with the clearance of apoptotic cells by inflammatory monocytes. In parallel, may regulate actin polymerization which is crucial for several biological processes, including macrophage function. May also regulate macrophage function through regulation of the peroxisome proliferator activated receptor signaling pathway (By similarity). Finally, it is also involved in the cellular response to IL13/interleukin-13 (PubMed:21831839). In addition to its role in the immune and inflammatory responses, may play a role in epithelial wound healing in the cornea maybe through production of lipoxin A4. May also play a role in endoplasmic reticulum stress response and the regulation of bone mass (By similarity).

Disease susceptibility may be associated with variations affecting the gene represented in this entry. Met at position 560 may confer interindividual susceptibility to coronary artery disease (CAD) (PubMed:17959182).
