17-178 4.03e-99

complement protein C8 gamma; Human complement protein C8 gamma, together with C8alpha and C8beta, form one of five components of the cytolytic membrane attack complex (MAC), a pore-like structure that assembles on bacterial membranes. C8alpha and C8gamma form a disulfide-linked heterodimer that is noncovalently associated with C8beta. MAC plays an important role in the defense against gram-negative bacteria and other pathogenic organisms. C8gamma 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.

16-168 2.91e-17

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.

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. 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.

26-163 8.41e-05

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.

13-119 1.83e-03

retinol-binding protein 4 and similar proteins; Retinol-Binding Protein 4 (RBP4) is a plasma protein that transports retinol (vitamin A) from the liver stores to the peripheral tissues. The RBP4-retinol complex interacts with transthyretin (TTR - transports thyroxine and retinol) which protects it from renal excretion. In addition to retinol, other endogenous and synthetic retinoids bind RBP4, including all-trans and 13-cis retinoic acid, retinyl acetate, N-(ethyl)retinamide, and fenretinide. This group also includes purpurin, a retinol-specific protein that plays a role in neural retina cell adhesion during development of the chicken retina; it also binds retinol and may participate in retinol transporter in the retina. 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.
