The encoded protein converts arachidonic acid exclusively to 15S-hydroperoxyeicosatetraenoic acid, while metabolizing linoleic acid less effectively. This gene is located in a cluster of related genes and a pseudogene that spans approximately 100 kilobases on the short arm of chromosome 17. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]. * **UniProt Summary**: 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. Converts arachidonic acid to 15S- hydroperoxyeicosatetraenoic acid/(15S)-HPETE. Also acts on linoleic acid to produce 13-hydroxyoctadecadienoic acid/13-HPODE. Has no detectable 8S-lipoxygenase activity but reacts with (8S)- HPETE to produce (8S,15S)-diHPETE. May regulate progression through the cell cycle and cell proliferation. May also regulate cytokine secretion by macrophages and therefore play a role in the immune response. May also regulate macrophage differentiation into proatherogenic foam cells. {ECO:0000269|PubMed:10625675, ECO:0000269|PubMed:11839751, ECO:0000269|PubMed:12704195, ECO:0000269|PubMed:16112079, ECO:0000269|PubMed:18067895, ECO:0000269|PubMed:22912809, ECO:0000269|PubMed:24497644}. |Lipoxygenase| |PLAT| |arachidonate 8(S)-lipoxygenase activity| |linoleate 13S-lipoxygenase activity| |arachidonate 15-lipoxygenase activity| |hepoxilin biosynthetic process| |hepoxilin metabolic process| |positive regulation of peroxisome proliferator activated receptor signaling pathway| |regulation of peroxisome proliferator activated receptor signaling pathway| |positive regulation of chemokine secretion| |lipoxygenase pathway| |positive regulation of macrophage derived foam cell differentiation| |regulation of chemokine secretion| |positive regulation of keratinocyte differentiation| |linoleic acid metabolic process| |positive regulation of epidermal cell differentiation| |regulation of macrophage derived foam cell differentiation| |long-chain fatty acid biosynthetic process| |positive regulation of epidermis development| |regulation of keratinocyte differentiation| |prostate gland development| |unsaturated fatty acid biosynthetic process| |positive regulation of chemokine production| |arachidonic acid metabolic process| |positive regulation of epithelial cell differentiation| |regulation of epidermal cell differentiation| |extrinsic component of membrane| |regulation of chemokine production| |regulation of epidermis development| |unsaturated fatty acid metabolic process| |icosanoid metabolic process| |long-chain fatty acid metabolic process| |fatty acid biosynthetic process| |iron ion binding| |positive regulation of cytokine secretion| |regulation of epithelial cell differentiation| |lipid binding| |fatty acid derivative metabolic process| |monocarboxylic acid biosynthetic process| |regulation of cytokine secretion| |negative regulation of growth| |negative regulation of cell migration| |positive regulation of protein secretion| |negative regulation of cell motility| |positive regulation of peptide secretion| |carboxylic acid biosynthetic process| |organic acid biosynthetic process| |negative regulation of cellular component movement| |urogenital system development| |fatty acid metabolic process| |negative regulation of locomotion| |cytoskeleton| |positive regulation of secretion by cell| |gland development| |positive regulation of protein transport| |reproductive structure development| |reproductive system development| |positive regulation of secretion| |positive regulation of cytokine production| |positive regulation of establishment of protein localization| |regulation of protein secretion| |regulation of peptide secretion| |monocarboxylic acid metabolic process| |negative regulation of cell cycle| |lipid biosynthetic process| |small molecule biosynthetic process| |developmental process involved in reproduction| |regulation of growth| |negative regulation of cell population proliferation| |regulation of cytokine production| |regulation of protein transport| |calcium ion binding| |regulation of peptide transport| |regulation of establishment of protein localization| |regulation of secretion by cell| |regulation of secretion| |regulation of cell migration| |carboxylic acid metabolic process| |regulation of cell motility| |apoptotic process| |cellular lipid metabolic process| |oxidation-reduction process| |positive regulation of cell differentiation| |regulation of locomotion| |positive regulation of transport| |regulation of cellular component movement| |oxoacid metabolic process| |organic acid metabolic process| |regulation of protein localization| |programmed cell death| |cell death| |regulation of cell cycle| |lipid metabolic process| |positive regulation of developmental process| |reproductive process| |reproduction| |regulation of cell population proliferation| |positive regulation of signal transduction| |positive regulation of multicellular organismal process| |small molecule metabolic process| |regulation of cell differentiation| |positive regulation of cell communication| |positive regulation of signaling| |regulation of transport| |membrane| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp42|BI-6727 0.001μM R01 exp42]]|-1.91| |[[:results:exp500|LY2090314 0.003μM R08 exp500 no dilution day6]]|-1.83| |[[:results:exp115|A-366 10μM R03 exp115]]|1.86| No correlation found to any other genes in chemogenomics.
