26-168 1.33e-63

bacterial lipocalin Blc, Arabidopsis thaliana temperature-induced lipocalin-1, and similar proteins; Escherichia coli bacterial lipocalin (Blc, also known as YjeL) is an outer membrane lipoprotein involved in the storage or transport of lipids necessary for membrane maintenance under stressful conditions. Blc has a binding preference for lysophospholipids. This group includes eukaryotic lipocalins such as Arabidopsis thaliana temperature-induced lipocalin-1 (TIL) which is involved in thermotolerance, oxidative, salt, drought and high light stress tolerance, and is needed for seed longevity by ensuring polyunsaturated lipids integrity. 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.

22-170 4.66e-39

apolipoprotein D and similar proteins; Human apolipoprotein D (ApoD) is a small glycoprotein associated with high density lipoproteins (HDL) in plasma. It appears promiscuous since it can bind hydrophobic ligands belonging to different lipid groups, with different shapes and biochemical properties; however, it exhibits specificity between very similar lipidic species. Some ligands, such as progesterone and arachidonic acid, bind to the ligand-binding pocket with high affinity, while others may interact with ApoD via its region of surface hydrophobicity. This hydrophobic surface cluster may facilitate its association with HDL particles and facilitate its insertion into cellular lipid membranes. Drosophila NLaz and Schistocerca Laz belong to this group, and share functional properties with human ApoD, including regulation of lifespan, lipid and carbohydrate metabolism control, and protection against oxidative stress or starvation. This group also includes Sandercyanin, a blue protein secreted in the skin mucus of blue forms of walleye, Sander vitreus. Walleye is an important golden yellow commercial and sport fish; the findings of blue walleye are recent. 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.

29-170 6.44e-09

crustacyanin Type I CRTC and Type II CRTA subunits; Alpha crustacyanin bound with the carotenoid astaxanthisn (AXT) is the predominant cartenoprotein generating the slate-grey/blue color of the lobster carapace. Crustacyanin forms heterodimers (beta-crustacyanin) or complexes of 16 subunits (alpha-crustacyanin) assembled from beta-crustacyanin. Beta-crustacyanin is formed from one type I CRTC lipocalin subunit, and one type II CRTA lipocalin subunit (and two bound astaxanthin molecules). Homarus gammarus (European lobster) crustacyanin has of five distinct subunits evident on 6 M urea-PAGE gels: type I CRTC ( A1, C1, C2) and type II CRTA ( A2, A3). Homarus americanus crustacyanin consists of only two major subunits, namely type I CRTC (H1) and type II CRTA (H2), both of which behave like Ax subunits on a 6 M urea-PAGE gel. This family includes both type I CRTC subunit and type II CRTA subunits and 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.

27-133 7.70e-05

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.
