5-Lipoxygenase

5-Lipoxygenase (5-LOX or 5-LO) is an enzyme that in humans is encoded by the ALOX5 gene. 5-lipoxygenase is a member of the lipoxygenase family of enzymes. It transforms EFAs into leukotrienes and is a current target for pharmaceutical intervention in a number of diseases. 5-LO catalyzes oxidation of AA at the 5-position to yield 5-HpETE. 5-LO then converts 5-HpETE to leukotriene A4. Recently, oxidized lipid products of 5-LO have been measured in membranes of neutrophils in the form of esterified-5-HETE phospholipids. These novel products have biological activities including inhibition of neutrophil extracellular traps. 5-LO is a target for pharmaceutical intervention in CAD. Some people with variant alleles for 5-LO are at elevated risk for CAD. 5-LO is expressed in brain cells and may participate in neuropathologic processes.
