Function
Lipid transport protein in adipocytes. Binds both long chain fatty acids and retinoic acid. Delivers long-chain fatty acids and retinoic acid to their cognate receptors in the nucleus (By similarity). Has the highest binding affinity for linoleic acid and decreasing relative affinity for eicosapentaenoic acid (EPA), alpha-linolenic acid (ALA), docosahexaenoic acid (DHA), oleic acid, palmitic acid and stearic acid, respectively (PubMed:26206084).
