Coactosin-like protein (COTL1orCLP) is a protein that in humans is encoded by the COTL1 gene.^[5][6][7][8]

This gene encodes one of the numerous actin-binding proteins which regulate the actin cytoskeleton. This protein binds F-actin, and also interacts with and thereby stabilizes 5-lipoxygenase (ALOX5). Although this gene has been reported to map to chromosome 17 in the Smith-Magenis syndrome region, the best alignments for this gene are to chromosome 16. The Smith-Magenis syndrome region is the site of two related pseudogenes.^[8]

COTL1 has been shown to interact with ALOX5.^[9] ALOX5 is the first committed enzyme in the metabolism of arachidonic acid to an array of biologically important cell signaling agents: a) the pro-inflammatory mediator, leukotriene B4 (LTB4); b) the airways constrictors, LTC4, LTD4, and LTE4; c) the 5-hydroxyeicosatetraenoic acid family of pro-inflammatory and pro-allergic reactions mediators, 5-HETE and 5-oxo-eicosatetraenoic acid. ALOX5 also contributes to the metabolism of arachidonic acid and other polyunsaturated fatty acids to agents which act block inflammation and allergic reactions, the specialized pro-resolving mediators of the lipoxin and resolvin subclasses. Based on in vitro studies, COTL1 serves to stabilize ALOX5, acting as a chaperone or scaffold, to avert the enzyme's inactivation and thereby to promote its metabolic activity.^[10]
