The ALOX5AP (5-lipoxygenase-activating protein) recombinant protein is a key component in the leukotriene biosynthesis pathway, which plays a central role in inflammatory and immune responses. Also known as FLAP (Five-Lipoxygenase-Activating Protein), ALOX5AP is a membrane-bound protein expressed in myeloid cells, such as neutrophils, monocytes, and macrophages. It facilitates the interaction between 5-lipoxygenase (5-LO) and arachidonic acid, a critical step in converting arachidonic acid to leukotriene A4 (LTA4), a precursor for pro-inflammatory leukotrienes (LTB4. LTC4. LTD4). These lipid mediators are involved in bronchoconstriction, vascular permeability, and chemotaxis, linking ALOX5AP to asthma, atherosclerosis, and other inflammatory diseases.
Recombinant ALOX5AP protein is typically produced using prokaryotic or eukaryotic expression systems, enabling studies of its structure-function relationships and interactions with 5-LO or inhibitors. Purified recombinant variants often include tags (e.g., His-tag) for isolation and detection. Researchers use this protein in vitro to reconstitute leukotriene synthesis pathways, screen therapeutic compounds, or investigate genetic polymorphisms affecting inflammatory disease susceptibility.
Pharmaceutical interest in ALOX5AP stems from its potential as a drug target. FLAP inhibitors, such as MK-886 and GSK2190915. have been explored to block leukotriene production, offering alternatives to corticosteroids in managing inflammation. Studies with recombinant ALOX5AP also clarify its role in cardiovascular diseases, where leukotrienes promote plaque formation. Despite challenges in targeting membrane-associated proteins, ALOX5AP remains a focus for developing anti-inflammatory therapies.
