== Function ==
[[http://www.uniprot.org/uniprot/EXFAB_COTJA EXFAB_COTJA]] Siderocalin-like lipocalin tightly binding a variety of bacterial ferric siderophores, also binds long-chain unsaturated fatty acids such as linoleic acid, oleic acid, arachidonic acid and, with a lower affinity, long chain saturated fatty acids such as steraic acid. May act as an antibacterial factor, through dual ligand specificity, both as a siderophore-sequestrating molecule and a lysophosphatidic acid (LPA) sensor.<ref>PMID:20826777</ref> <ref>PMID:21951132</ref>
