lipocalin similar to human epididymal-specific lipocalin-8, mouse lipocalin-5 and -8, and similar proteins; Lipocalin 5 (LCN5; also known as epididymal retinoic acid binding protein Erabp, mouse epididymal protein 10, MEP10, and E-RABP) and Lipocalin 8 (LCN8; also known as mouse epididymal protein 17, MEP17) are homologous proteins belonging to the epididymis-specific lipocalins; they may play a role in male fertility, and may act as retinoid carrier proteins within the epididymis. In mice, genes encoding the two proteins are contiguous; in humans, there is one gene LCN8 (which has been previously called LCN5). 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/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.

5-134 2.99e-07

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. 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.

beta-lactoglobulin and similar proteins; Beta-Lactoglobulin (beta-LG) is the major whey protein of ruminant species and present in the milk of many other species, with a notable exception of human. It is the major allergen of bovine milk. Beta-LG has been shown to bind hydrophobic ligands such as curcumin, vitamin E or fatty acids, or hydrophilic such as vitamin B9. This group also includes human glycodelin (also known as placental protein 14, pregnancy-associated endometrial alpha-2 globulin, and progestagen-associated endometrial protein) which is involved in crucial biological processes such as reproduction and immune reaction. Four glycoforms of glycodelin have been identified in reproductive tissue that differ in glycosylation and biological activity. 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.

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. 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-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.
