lipocalin-1, -3, -4, -13 and similar proteins; Lipocalin-1 (LCN1, also known as tear lipocalin, von ebner's gland protein, or tear specific prealbumin), the main lipid carrier in human tears, is critical to functions involving lipids in protection of the ocular surface. Its large ligand pocket accommodates a range of ligands including alkyl alcohols, glycolipids, phospholipids, cholesterol, steroids, and siderophores. Lipocalin-3 (LCN3, also known as vomeronasal secretory protein 1) and lipocalin-4 (LCN4, also known as vomeronasal secretory protein 2) are involved in transport of lipophilic molecules, and are possibly pheromone-carriers. Lipocalin-13 (LCN13, also known as odorant binding protein 2A) may bind and transport small hydrophobic volatile molecules with a higher affinity for aldehydes and large fatty acids. Another member of this family is late lactation protein B (LLPB), a milk protein produced during the late phase of lactation, which may be involved in transporting a small ligand released during the hydrolysis of milk fat. This group belongs to the lipocalin/cytosolic fatty-acid binding protein family which have a large beta-barrel ligand-binding cavity. Lipocalins are mainly low molecular weight extracellular proteins that bind principally small hydrophobic ligands, and form covalent or non-covalent complexes with soluble macromolecules, as well as membrane bound-receptors. They participate in processes such as ligand transport, modulation of cell growth and metabolism, regulation of immune response, smell reception, tissue development and animal behavior. Cytosolic fatty-acid binding proteins, also bind hydrophobic ligands in a non-covalent, reversible manner, and have been implicated in intracellular uptake, transport and storage of hydrophobic ligands, regulation of lipid metabolism and sequestration of excess toxic fatty acids, as well as in signaling, gene expression, inflammation, cell growth and proliferation, and cancer development.

38-136 5.99e-06

major urinary proteins (MUPs) and similar proteins; Mouse urine contains major urinary proteins (MUPs) which bind low molecular weight hydrophobic organic compounds such as urinary volatile pheromones such as the male-specific 2-sec-butyl-4,5-dihydrothiazole (SB2HT) which hastens puberty in female mice. The association between MUPs and these volatiles slows the release of the volatiles into the air from urine marks. MUPs may also act as pheromones themselves. MUPs, expressed in the nasal and vomeronasal mucosa, may be important for delivering urinary volatiles to receptors in the vomeronasal organ. This group includes MUPs encoded by central genes in the MUP cluster, as well as those encoded by peripheral genes such as Darcin/Mup20 which binds most of the male pheromone SB2HT in urine and was the first MUP shown to have male pheromonal activity in its own right. This group includes rat MUPs (also called alpha-2U globulins) and other lipocalins such as major horse allergen Equ c 1 and boar salivary lipocalin, a pheromone-binding protein specifically expressed in the submaxillary glands of the boar. It belongs to the lipocalin/cytosolic fatty-acid binding protein family which have a large beta-barrel ligand-binding cavity. Lipocalins are mainly low molecular weight extracellular proteins that bind principally small hydrophobic ligands, and form covalent or non-covalent complexes with soluble macromolecules, as well as membrane bound-receptors. They participate in processes such as ligand transport, modulation of cell growth and metabolism, regulation of immune response, smell reception, tissue development and animal behavior. Cytosolic fatty-acid binding proteins, also bind hydrophobic ligands in a non-covalent, reversible manner, and have been implicated in intracellular uptake, transport and storage of hydrophobic ligands, regulation of lipid metabolism and sequestration of excess toxic fatty acids, as well as in signaling, gene expression, inflammation, cell growth and proliferation, and cancer development.

26-135 8.36e-06

lipocalin domain of alpha1-microglobulin and similar proteins; Alpha(1)-microglobulin (A1M, also known as protein AMBP, alpha-1 microglycoprotein, and protein HC), has immunosuppressive properties, such as inhibition of antigen induced lymphocyte cell-proliferation, cytokine secretion, and oxidative burst of neutrophils. A1M may participate in the reducing and scavenging of biological pro-oxidants such as heme and heme-proteins. It binds heme strongly, and a C-terminally processed form of the protein degrades the heme. It can reduce cytochrome C, nitroblue tetrazolium, methemoglobin and free iron, using NADH, NADPH or ascorbate as cofactor. Intravenous administration of recombinant A1M in animal models eliminates or significantly reduces the manifestations of preeclampsia. A1M is a useful biomarker in clinical diagnostics for monitoring pre-eclampsia, hepatitis E, renal tubular dysfunction, and renal toxicity. A1M belongs to the lipocalin/cytosolic fatty-acid binding protein family which have a large beta-barrel ligand-binding cavity. Lipocalins are mainly low molecular weight extracellular proteins that bind principally small hydrophobic ligands, and form covalent or non-covalent complexes with soluble macromolecules, as well as membrane bound-receptors. They participate in processes such as ligand transport, modulation of cell growth and metabolism, regulation of immune response, smell reception, tissue development and animal behavior. Cytosolic fatty-acid binding proteins, also bind hydrophobic ligands in a non-covalent, reversible manner, and have been implicated in intracellular uptake, transport and storage of hydrophobic ligands, regulation of lipid metabolism and sequestration of excess toxic fatty acids, as well as in signaling, gene expression, inflammation, cell growth and proliferation, and cancer development.

18-119 1.27e-04

extracellular fatty acid-binding protein; Ex-FABP (also known as siderocalin, lipocalin Q83 or protein Ch21) displays a dual ligand binding mode as it can bind siderophore and fatty acids simultaneously. ExFABP has a cavity which extends through the protein and has two separate ligand specificities, one for bacterial siderophores at one end, and other specifically binding co-purified lysophosphatidic acid (LPA), a potent cell signaling molecule, at the other end. As well as acting as an LPA "sensor", Ex-FABP is bacteriostatic, and tightly binds the 2,3-catechol-type ferric siderophores enterobactin, bacillibactin, and parabactin, associated with enteric bacteria and Gram-positive bacilli. This group belongs to the lipocalin/cytosolic fatty-acid binding protein family which have a large beta-barrel ligand-binding cavity. Lipocalins are mainly low molecular weight extracellular proteins that bind principally small hydrophobic ligands, and form covalent or non-covalent complexes with soluble macromolecules, as well as membrane bound-receptors.

lipocalin 2 and 12 and similar proteins; Lipocalin-2 (LCN2, also known as siderocalin, uterocalin, neutrophil gelatinase-associated lipocalin) is expressed in renal, endothelial, liver, smooth muscle cells, cardiomyocytes, in various populations of immune cells and dendritic cells. Roles ascribed to LCN2 include chemotactic and bacteriostatic effects, and iron trafficking. LCN2 can also act as a growth factor. It plays a key role in the pathophysiology of renal and cardiovascular diseases, and is involved in various deleterious processes, such as inflammation and fibrosis. It is used as a renal injury biomarker. Lipocalin 12 (LCN12) is an epididymis-specific protein which binds all-trans retinoic acid. It may act as a retinoid carrier protein within the epididymis and play a role in male reproduction. This group belongs to the lipocalin/cytosolic fatty-acid binding protein family which have a large beta-barrel ligand-binding cavity. Lipocalins are mainly low molecular weight extracellular proteins that bind principally small hydrophobic ligands, and form covalent or non-covalent complexes with soluble macromolecules, as well as membrane bound-receptors.
