Abstract
Leukotrienes are lipid messenger molecules that are secreted by leukocytes to orchestrate a rapid and prolonged immune response. The enzyme 5-lipoxygenase catalyzes the rate-limiting first two steps in the synthesis of leukotrienes from arachidonic acid. Although it has long been known that 5-lipoxygenase moves from the cytoplasm to a membrane following activation, it has only recently been recognized that the enzyme may shuttle into and out of the nucleus before activation. The regulation of this movement of soluble 5-lipoxygenase between the cytoplasm and the nucleoplasm, as well as its impact on 5-lipoxygenase action, leukotriene synthesis and cell function, is only now being elucidated. This review details the state of our understanding of the nuclear import of 5-lipoxygenase and its potential importance in immunity.
