GeneCards Summary for ALOX15 Gene
ALOX15 (Arachidonate 15-Lipoxygenase) is a Protein Coding gene. Diseases associated with ALOX15 include osteoporosis and asthma. Among its related pathways are Apoptotic Pathways in Synovial Fibroblasts and Metabolism. GO annotations related to this gene include iron ion binding and arachidonate 15-lipoxygenase activity. An important paralog of this gene is ALOX12.
UniProtKB/Swiss-Prot for ALOX15 Gene
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 into 12-hydroperoxyeicosatetraenoic acid/12-HPETE and 15-hydroperoxyeicosatetraenoic acid/15-HPETE. Also converts linoleic acid to 13-hydroperoxyoctadecadienoic acid. May also act on (12S)-hydroperoxyeicosatetraenoic acid/(12S)-HPETE to produce hepoxilin A3. 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. Finally, it is also involved in the cellular response to IL13/interleukin-13. 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.
Lipoxygenases (LOXs) are a family of non-heme iron dioxygenases that are involved in the production and metabolism of fatty acid hydroperoxidases. There are six lipoxygenase isozymes; 5-LOX, 12R-LOX, 12S-LOX, 15-LOX-1 and 15-LOX-2, which catalyze the regio-selective addition of oxygen into arachidonic acid, and epidermal LOX (E-LOX) which metabolizes 12R-hydroperoxyeicosatetraenoic acid (12R-HPETE) to a specific epoxyalcohol compound. Different isozymes have different physiological roles; 5-, 12R-, 12S- and 15-LOX-1 have proliferative, antiapoptotic and angiogenic functions whilst 15-LOX-2 has roles in differentiation, growth arrest and the induction of apoptosis. E-LOX, the most divergent member of this family, is involved in terminal differentiation of keratinocytes and has a major role in skin barrier function. Perturbations in lipoxygenase enzymes have been implicated in various human diseases including bronchial asthma, atherosclerosis, osteoporosis and some cancers.
