Summaries for ALOX5AP Gene

Entrez Gene Summary for ALOX5AP Gene

  • This gene encodes a protein which, with 5-lipoxygenase, is required for leukotriene synthesis. Leukotrienes are arachidonic acid metabolites which have been implicated in various types of inflammatory responses, including asthma, arthritis and psoriasis. This protein localizes to the plasma membrane. Inhibitors of its function impede translocation of 5-lipoxygenase from the cytoplasm to the cell membrane and inhibit 5-lipoxygenase activation. Alternatively spliced transcript variants encoding different isoforms have been identified for this gene. [provided by RefSeq, Feb 2011]

GeneCards Summary for ALOX5AP Gene

ALOX5AP (Arachidonate 5-Lipoxygenase-Activating Protein) is a Protein Coding gene. Diseases associated with ALOX5AP include stroke, ischemic and psoriasis. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include protein homodimerization activity and enzyme binding. An important paralog of this gene is MGST2.

UniProtKB/Swiss-Prot for ALOX5AP Gene

  • Required for leukotriene biosynthesis by ALOX5 (5-lipoxygenase). Anchors ALOX5 to the membrane. Binds arachidonic acid, and could play an essential role in the transfer of arachidonic acid to ALOX5. Binds to MK-886, a compound that blocks the biosynthesis of leukotrienes.

Tocris Summary for ALOX5AP 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 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.

  • Ischemic stroke (ISCHSTR) [MIM:601367]: A stroke is an acute neurologic event leading to death of neural tissue of the brain and resulting in loss of motor, sensory and/or cognitive function. Ischemic strokes, resulting from vascular occlusion, is considered to be a highly complex disease consisting of a group of heterogeneous disorders with multiple genetic and environmental risk factors. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
  • Note=Genetic variations in ALOX5AP may be associated with susceptibility to myocardial infarction. Involvement in myocardial infarction is however unclear: according to some authors (PubMed:14770184), a 4-SNP haplotype in ALOX5AP confers risk of myocardial infarction, while according to other (PubMed:17304054) ALOX5AP is not implicated in this condition. {ECO:0000269 PubMed:14770184, ECO:0000269 PubMed:17304054}.
