5-lipoxygenase and FLAP

Prostaglandins Leukot Essent Fatty Acids. 2003 Aug-Sep;69(2-3):99-109. doi: 10.1016/s0952-3278(03)00070-x.

Abstract

The initial steps in the biosynthesis of leukotrienes from arachidonic acid are carried out by the enzyme 5-lipoxygenase (5-LO). In intact cells, the helper protein 5-LO activating protein (FLAP) is necessary for efficient enzyme utilization of endogenous substrate. The last decade has witnessed remarkable progress in our understanding of these two proteins. Here we review the molecular and cellular aspects of the expression, function, and regulation of 5-LO and FLAP.
