Entrez Gene Summary for ALOX15B Gene

  • This gene encodes a member of the lipoxygenase family of structurally related nonheme iron dioxygenases involved in the production of fatty acid hydroperoxides. 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]

GeneCards Summary for ALOX15B Gene

ALOX15B (Arachidonate 15-Lipoxygenase, Type B) is a Protein Coding gene. Diseases associated with ALOX15B include prostate adenocarcinoma and autosomal recessive congenital ichthyosis. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include iron ion binding and linoleate 13S-lipoxygenase activity. An important paralog of this gene is ALOX12.

UniProtKB/Swiss-Prot for ALOX15B 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 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.
