30-188 2.47e-70

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.

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.

major allergens Bla g 4 and Per a 4; Inhalant allergens from cockroaches are an important cause of asthma. Bla g 4 and Per a 4 are male pheromone transport lipocalins, and both are major allergens. Bla g 4 is produced by Blattella germanica (German cockroach) and has been shown to bind two biogenic amines, tyramine and octopamine which may be its physiological ligands. Per a 4 is produced by Periplaneta americana (American cockroach) and may bind different ligands from Bla g 4 or have different modes for tyramine/octopamine binding. 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.

30-192 3.33e-14

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.

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.

126-179 2.37e-03

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.

126-158 5.76e-03

Triatominae salivary lipocalins such as Rhodnius prolixus LTBP1 and Meccus pallidipennis triabin, and similar proteins; This subfamily includes various insect proteins found in the saliva of Triatominae (kissing bugs), including Rhodnius prolixus leukotriene-binding LTBP1. Rhodnius prolixus, a vector of the pathogen Trypanosoma cruzi, sequesters cysteinyl leukotrienes during feeding to inhibit immediate inflammatory responses; LTBP1 binds leukotrienes C4 (LTC4), D4 (LTD4), and E4 (LTE4). Meccus pallidipennis (syn Triatoma pallidipennis) triabin is a potent and selective thrombin inhibitor. It also includes Triatoma protracta procalin, a major salivary allergen which causes an allergic reaction in humans. 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.
