Description

5-lipoxygenase-activating protein (FLAP) is an integral membrane protein found in cells that produce leukotrienes, the biologically active metabolites of arachidonic acid that have been implicated in a variety of inflammatory responses, including asthma, arthritis and psoriasis [PMID: 2174053].

FLAP appears to activatate 5-lipoxygenase (5LOX) by facilitating its binding to membranes [PMID: 8245774]. It binds arachidonic acid, and may play a role in its transfer to 5LOX. The protein has been shown to bind to MK-886, a compound that blocks leukotriene biosynthesis [PMID: 2174053, PMID: 2300173].
