Leukotriene synthesis also requires 5-lipoxygenase-activating protein (FLAP, ALOX5AP), a nuclear membrane-bound protein that binds arachidonic acid and is thought to activate 5-LO. A number of related leukotrienes (i.e. B , C , D ) are derived from LTA and together these lipid mediators function in immune reaction regulation. 5-LO is primarily expressed in polymorphonuclear leukocytes, peripheral blood monocytes, macrophages, and mast cells (1,3). Overexpression of 5-LO protein is seen in certain cancer cells and is associated with poor diagnosis (1,4). Depending upon the cell type, 5-LO is localized to either the cytosol or the nucleus of quiescent cells (5). Following stimulation, 5-LO translocates to the nucleus and associates with FLAP to catalyze LTA synthesis (2,3). Phosphorylation of specific residues can regulate 5-LO enzymatic activity. Phosphorylation of 5-LO at Ser523 by PKA family kinases inhibits oxygenase activity (6,7) while MAPKAP2 and ERK family kinase phosphorylation at Ser271 and Ser663 stimulates 5-LO enzymatic activity (8,9).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\n5-lipoxygenase; 5-LO; 5-LOX; 5LPG; ALOX5; Arachidonate 5-lipoxygenase; arachidonic acid 5-lipoxygenase; leukotriene A4 synthase; LOG5; LOX-5; LOX5; MGC163204; Polyunsaturated fatty acid 5-lipoxygenase\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 78\nSource\/Isotype: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46800979067049,"sku":"3289S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-3289s","provider":"Iright","version":"1.0","type":"link"}
