LCN15 (Lipocalin 15) is located on human chromosome 9q34.3. The LCN15 protein is biasedly expressed in duodenum, colon and other tissues. Structurally, the encoded LCN15 protein is reported to be 20454 Da in mass. The LCN15 gene is conserved in chimpanzee, Rhesus monkey, dog, cow, mouse, and chicken. 99 organisms have orthologs with human gene LCN15. LCN15 is related to transporter activity and small molecule binding. Among its related pathways are Transport of vitamins, nucleosides, and related molecules and Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds. An important paralog of this gene is PTGDS. LCN15 (Lipocalin 15) is associated with some diseases, such as Retrograde Amnesia.
