Summaries for ALOX5 Gene

Entrez Gene Summary for ALOX5 Gene

  • This gene encodes a member of the lipoxygenase gene family and plays a dual role in the synthesis of leukotrienes from arachidonic acid. The encoded protein, which is expressed specifically in bone marrow-derived cells, catalyzes the conversion of arachidonic acid to 5(S)-hydroperoxy-6-trans-8,11,14-cis-eicosatetraenoic acid, and further to the allylic epoxide 5(S)-trans-7,9-trans-11,14-cis-eicosatetrenoic acid (leukotriene A4). Leukotrienes are important mediators of a number of inflammatory and allergic conditions. Mutations in the promoter region of this gene lead to a diminished response to antileukotriene drugs used in the treatment of asthma and may also be associated with atherosclerosis and several cancers. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

GeneCards Summary for ALOX5 Gene

ALOX5 (Arachidonate 5-Lipoxygenase) is a Protein Coding gene. Diseases associated with ALOX5 include Asthma and Arthus Reaction. Among its related pathways are NF-kappaB Signaling and PEDF Induced Signaling. GO annotations related to this gene include iron ion binding and arachidonate 5-lipoxygenase activity. An important paralog of this gene is ALOX15.

UniProtKB/Swiss-Prot for ALOX5 Gene

  • Catalyzes the first step in leukotriene biosynthesis, and thereby plays a role in inflammatory processes.

Tocris Summary for ALOX5 Gene

  • 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, 15-LOX-2 and E-LOX.
