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.

lipocalin-type prostaglandin D synthase; Lipocalin-type prostaglandin D synthase (L-PGDS; EC:5.3.99.2) is a secreted enzyme and the second most abundant protein in human cerebrospinal fluid. L-PGDS acts as both, an enzyme and as a lipid transporter, converting prostaglandin H2 to prostaglandin D2 and serving as a carrier for hydrophobic ligands including retinoids, hemoglobin metabolites, thyroid hormones, gangliosides, and fatty acids. L-PGDS belongs to the lipocalin/cytosolic fatty-acid binding protein family which has 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/cytosolic fatty acid-binding protein family; Lipocalins are diverse, 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 have a large beta-barrel ligand-binding cavity. Members include retinol-binding protein, retinoic acid-binding protein, complement protein C8 gamma, Can f 2, apolipoprotein D, extracellular fatty acid-binding protein, beta-lactoglobulin, oderant-binding protein, and bacterial lipocalin Blc. Lipocalins are involved in many important 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 are involved in protection and shuttling of fatty acids within the cell, and in acquisition and removal of fatty acids from intracellular sites.

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.

27-173 1.43e-08

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.

30-162 1.48e-04

Lipocalin odorant-binding protein and similar proteins; Odorant-binding proteins (OBPs) transport small hydrophobic molecules in the nasal mucosa of vertebrates. This subfamily includes mouse odorant-binding protein 1a (Obp1a), Obp1b, and probasin. Mouse Obp1a and Obp1b, which are expressed in the nasal mucosa, bind the chemical odorant 2-isobutyl-3-methoxypyrazine, and may form a OBPO1a/Opb1B heterodimer. Mouse probasin may play a role in the biology of the prostate gland. This group also includes hamster female-specific lacrimal gland protein (FLP) and aphrodisin. FLP may bind tear lipids or lipid-like pheromones found in hamster tears; aphrodisin is found in hamster vaginal discharge, carries pheromones, and stimulates copulatory behavior in males. This group also includes dog allergen Ca f4 which is expressed by tongue epithelial tissue and found in saliva and dander. Bovine OBP is believed to act as a homodimer, having the C-terminal alpha-helix of each monomer stacking against the beta-barrel of the other monomer; this is possible due to its lack of cysteines and therefore lack of disulfide bonds. 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.

lipocalin 9; Lipocalin 9 (LCN9) is specifically expressed in the epididymis. It belongs to the lipocalin/cytosolic fatty-acid binding protein family. Lipocalins are typically small extracellular proteins that bind small hydrophobic molecules, such as lipids, steroid hormones, bilins, and retinoids and form covalent or non-covalent complexes with soluble macromolecules as well as membrane bound-receptors. They are involved in many important functions, like ligand transport, modulation of cell growth and metabolism, regulation of immune response, smell reception, tissue development and animal behavior.
