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.

fatty acid-binding protein ReP1-NCXSQ and similar proteins; Arthropod ReP1-NCXSQ (regulatory protein of the squid nerve sodium calcium exchanger) is required for MgATP stimulation of the squid nerve Na(+)/Ca(2+) exchanger NCXSQ1. ReP1-NCXSQ acts as a carrier of fatty acids; is possible that its biological ligand is palmitic acid, which is abundant in squid axons. The mechanism for fine-tuning of the regulation of NCXSQ1 by ReP1-NCXSQ may then involve the transport of palmitic acid. 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.

5-131 2.16e-27

cellular retinoic acid-binding protein 1; 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 CRABP1 (also known as CRABP, CRABP-I, CRABPI, RBP5), which is thought to play an important role in retinoic acid-mediated differentiation and proliferation processes. CRABP1 has been shown to modulate stem cell proliferation to affect learning and memory. It has also been shown to regulate CaMKII, excessive and/or persistent activation of which is detrimental in acute and chronic cardiac injury. 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).

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).

cellular retinoic acid-binding proteins (CRABP1 and CRABP2); 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. CRABP1 (also known as CRABP, CRABP-I, CRABPI, RBP5) is thought to play an important role in retinoic acid-mediated differentiation and proliferation processes. CRABP1 has been shown to modulate stem cell proliferation to affect learning and memory. It has also been shown to regulate CaMKII, excessive and/or persistent activation of which is detrimental in acute and chronic cardiac injury. CRABP2 (also known as CRABP-II, RBP6) 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 3; 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. This group includes human CRBP3 (also known as retinol-binding protein 5, HRBPiso) which is expressed at highest levels in kidney and liver. CRBP3 binds retinol, and may be a human intracellular carrier of retinol in such tissues. 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).

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.
