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.

fatty acid binding protein 5; FABP5 (also known as epidermal FABP, E-FABP, cutaneous fatty-acid-binding protein, C-FABP, psoriasis-associated fatty-acid-binding protein, KFABP, PA-FABP) binds a wide array of ligands. It is an intracellular carrier for long-chain fatty acids and related active lipids, and also selectively delivers specific fatty acids from the cytosol to the nucleus. Its ligands include vitamin A metabolite all-trans-retinoic acid, endocannabinoid and numerous synthetic drugs and probes. It may be involved in keratinocyte differentiation. Mouse FABP5 is found only in the monomeric form; however, human FABP5 can exist as a monomer as well as a domain-swapped dimer. This subgroup belongs to the intracellular fatty-acid binding protein (FABP) family, members of which are small proteins that 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.

Cellular retinoic acid-binding protein 2; Cellular retinoic acid-binding proteins (CRABPs) play a role in the metabolism of vitamin A and retinoic acid. They bind all trans retinoic acid, but not retinol. Retinol, the alcohol form of vitamin A, is an essential dietary nutrient. Within the cell, it gets oxidized into its biologically active acid form, retinoic acid, which interacts with the nuclear receptors (RARs and RXRs). The two CRABPs (CRABP1 AND CRABP2) differ in their pattern of expression across cells and developmental stages. Like other lipid binding proteins, CRABPs serve to solubilize and protect their ligand in the aqueous cytosol and transport retinoic acid between cellular compartments. This subgroup includes CRABP2 (also known as CRABP-II, RBP6) which transports retinoic acid to the nucleus, and delivers all-trans-retinoic acid to nuclear retinoic acid receptors. CRABPs belong to the intracellular fatty acid-binding protein (FABP) family, members of which are small proteins that bind hydrophobic ligands in a non-covalent, reversible manner, and besides CRABPS include the cellular retinol-binding protein (CRBPs) and the fatty acid-binding proteins (FABPs).

cellular retinol-binding protein 1; Cellular retinol-binding proteins (CRBPs) participate in the cellular uptake of vitamin A in the form of free retinol. Retinol achieves a higher chemical stability when bound to CRBPs, and its interaction with retinol-binding proteins allows the solubilization in the aqueous medium of the hydrophobic retinol molecule. There are four human CRBP types (CRBP1, -2, -3, -4) which differ in their tissue-specific expression pattern, as well as in their different ligand affinities. CRBP1 (also known as Retinol-Binding Protein 1, CRBP, RBPC, CRBP1, CRBPI, CRABP-I) is widely expressed in numerous tissues: it has highest abundance in the liver, kidney, lung, and retinal pigment epithelium cells of the eye. CRBP1 has a high affinity for retinol. It accepts retinol transported from the plasma to cytosol via a cell surface receptor named STRA6, which interacts with serum retinol-binding protein. CRBP1 can bind all-trans-retinol, all trans-retinal and 13-cis-retinol, but not 9-cis-retinol. CRBPs belong to the intracellular fatty acid-binding protein (FABP) family, members of which are small proteins that bind hydrophobic ligands in a non-covalent, reversible manner, and, besides CRBPS, include the cellular retinoic acid-binding proteins (CRABPs) and the fatty acid-binding proteins (FABPs).

liver bile acid-binding protein and similar proteins; Liver bile acid-binding protein (also known as "fatty acid-binding protein, liver", LB-FABP, L-BABP, L-FABP, FABP1) is present in the liver of the vertebrates fish, amphibians, reptiles, and birds but not in mammals. L-BABPs bind free fatty acids and their coenzyme A derivatives, bilirubin, and some other small molecules in the cytoplasm. The role of L-BABPs may be that of cellular and metabolic trafficking of bile acids; they may be involved in intracellular lipid transport. This subgroup belongs to the intracellular fatty acid-binding protein (FABP) family, members of which are small proteins that 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.

fatty acid-binding protein 1; Fatty acid-binding protein 1, FABP1 (also known as fatty acid-binding protein 1, liver FABP, L-FABP) occurs at high cytosolic concentration in liver, intestine, and, in the case of humans, also in kidney. FABP1 binds to two molecules of long-chain fatty acids; the two binding sites appear to be inter-dependent. FABP1 binds to fatty acyl-CoAs, peroxisome proliferators, prostaglandins, bile acids, bilirubin, heme, hydroxyl and hydroperoxyl metabolites of fatty acids, lysophosphatidic acids, selenium, and other hydrophobic ligands. FABP1 is down-regulated in about ten percent of hepatocellular carcinoma (HCC) as well as in colorectal cancer at the adenoma stage, but can also be over-expressed in various cancers. This subgroup belongs to the intracellular fatty acid-binding protein (FABP) family, members of which are small proteins that 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.

fatty acid-binding protein 2; FABP2 (also known as fatty acid-binding protein 2, intestinal, and I-FABP) is a small cytosolic protein abundantly present in mature enterocytes of small and large intestine and responsible for the absorption and intracellular transport of fatty acids. It is present throughout the small intestine; its highest expression is in the jejunum. It is a sensitive marker for damage to the intestinal epithelium. This subgroup belongs to the intracellular fatty acid-binding protein (FABP) family, members of which are small proteins that 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 transporters for small hydrophobic molecules, such as lipids, steroid hormones, bilins, and retinoids. The family also encompasses the enzyme prostaglandin D synthase (EC:5.3.99.2). Alignment subsumes both the lipocalin and fatty acid binding protein signatures from PROSITE. This is supported on structural and functional grounds. The structure is an eight-stranded beta barrel.
