Background

  • Function

    5 Lipoxygenase catalyzes the oxygenation of arachidonate ((5Z,8Z,11Z,14Z)-eicosatetraenoate) to 5-hydroperoxyeicosatetraenoate (5-HPETE) followed by the dehydration to 5,6- epoxyeicosatetraenoate (Leukotriene A4/LTA4), the first two steps in the biosynthesis of leukotrienes, which are potent mediators of inflammation. Also catalyzes the oxygenation of arachidonate into 8-hydroperoxyicosatetraenoate (8-HPETE) and 12-hydroperoxyicosatetraenoate (12-HPETE). Displays lipoxin synthase activity being able to convert (15S)-HETE into a conjugate tetraene. Although arachidonate is the preferred substrate, this enzyme can also metabolize oxidized fatty acids derived from arachidonate such as (15S)-HETE, eicosapentaenoate (EPA) such as (18R)- and (18S)-HEPE or docosahexaenoate (DHA) which lead to the formation of specialized pro-resolving mediators (SPM) lipoxin and resolvins E and D respectively, therefore it participates in anti-inflammatory responses. Oxidation of DHA directly inhibits endothelial cell proliferation and sprouting angiogenesis via peroxisome proliferator-activated receptor gamma (PPARgamma). It does not catalyze the oxygenation of linoleic acid and does not convert (5S)-HETE to lipoxin isomers. In addition to inflammatory processes, it participates in dendritic cell migration, wound healing through an antioxidant mechanism based on heme oxygenase-1 (HO-1) regulation expression, monocyte adhesion to the endothelium via ITGAM expression on monocytes. Moreover, it helps establish an adaptive humoral immunity by regulating primary resting B cells and follicular helper T cells and participates in the CD40-induced production of reactive oxygen species (ROS) after CD40 ligation in B cells through interaction with PIK3R1 that bridges ALOX5 with CD40. May also play a role in glucose homeostasis, regulation of insulin secretion and palmitic acid-induced insulin resistance via AMPK. Can regulate bone mineralization and fat cell differentiation increases in induced pluripotent stem cells[1][2][3][4][5][6][7][8][9][10][11][12][13].

    P09917 has 5 isomers: P09917-1: 77983 Da (predicted); P09917-2: 71564 Da (predicted); P09917-3: 74635 Da (predicted); P09917-4: 61244 Da (predicted); P09917-5: 56291 Da (predicted).
    Serine phosphorylation by MAPKAPK2 is stimulated by arachidonic acid (PubMed:11844797, PubMed:18978352). Phosphorylation on Ser-524 by PKA has an inhibitory effect (PubMed:15280375). Phosphorylation on Ser-272 prevents export from the nucleus (PubMed:11844797, PubMed:18978352). Phosphorylation at Ser-524 is stimulated by 8-bromo-3',5'-cyclic AMP or prostaglandin E2 (PubMed:26210919)

  • Subunit

    Homodimer (PubMed:21233389, PubMed:22516296). Interacts with ALOX5AP and LTC4S (PubMed:19233132). Interacts with COTL1, the interaction is required for stability and efficient catalytic activity (PubMed:19807693). Interacts with PIK3R1; this interaction bridges ALOX5 with CD40 after CD40 ligation in B cells and leads to the production of reactive oxygen species (ROS) (PubMed:21200133). Interacts (via PLAT domain) with DICER1 (via Dicer dsRNA-binding fold domain); this interaction enhances arachidonate 5-lipoxygenase activity and modifies the miRNA precursor processing activity of DICER1 (PubMed:19022417)
