靶點詳情

  • 功能：
    Could play a role in taste reception. Could be necessary for the concentration and delivery of sapid molecules in the gustatory system. Can bind various ligands, with chemical structures ranging from lipids and retinoids to the macrocyclic antibiotic rifampicin and even to microbial siderophores. Exhibits an extremely wide ligand pocket.
  • 基因功能參考文獻：
    1. At the relatively small concentrations in tears, all ceramides were complexed to tear lipocalin. PMID: 29331331
    2. Human neutrophil lipocalin (HNL) concentrations in serum or whole blood activated by formyl-methionine-leucine-phenylalanine (fMLP) were shown to distinguish acute infections of bacterial or viral cause with high accuracy. PMID: 26135974
    3. the possible relationship between ocular symptomatology, tear volume and tear break-up time (TBUT) and lipocalin, lactoferrin and lysozyme concentrations in the tear film were explored in a group of symptomatic dry-eyed postmenopausal (PM) women. PMID: 26366224
    4. Tear lysozyme, lactoferrin and lipocalin concentrations were determined via electrophoresis and the results for patients with or without eyelid tumors were compared. PMID: 25914748
    5. the crosstalk of dendritic cells with lipocalins alone has the potential to direct the type of immune response to these particular antigens. PMID: 26218644
    6. Serum concentrations of LCN1 and LCN2 were both elevated in patients with COPD. PMID: 24920892
    7. Tear lipocalin (TLC) is a major protein in tears and has a large ligand-binding cavity that allows the lipocalin to bind an extensive and diverse set of lipophilic molecules. PMID: 21791187
    8. Study has identified the first protein, lipocalin-1, in the secretome of human blastocysts that is associated with chromosome aneuploidy. PMID: 21324447
    9. The conserved disulfide bond of human tear lipocalin modulates conformation and lipid binding in a ligand selective manner.( PMID: 21466861
    10. Tear lipocalin with the bound artificial ligand 1,4-butanediol has been crystallized in space group P2(1) with four protein molecules in the asymmetric unit and its X-ray structure has been solved at 2.6 A resolution. PMID: 19770509

    16. Tear surface tension depends partly on presence of tear lipocalin/lipid complex. Tear proteins and lipid-free tear lipocalin lower surface tension. PMID: 12613963

    20. Hydrodynamic and solution properties of lipocalin from human tears show that the protein size and topology are the major determinants of rotational correlation time and a reason for deviation from the Stokes-Einstein relationship. PMID: 17869594
    21. Selective displacement of ANS molecules from the ANS-apoTL complex by stearic acid discriminates the internal and external binding sites. PMID: 17945179

    23. Results suggest that the excited protein states in tear lipocalin are not unique but consist of many substates. PMID: 19586017
