Fatty acid-binding protein from embryonic chick retina resembles mammalian heart fatty acid-binding protein.
PURPOSE Fatty acid-binding proteins (FABP) make up a family of cytosolic proteins of unknown function found in many tissues, including the embryonic chick retina. To further understand its function in the developing retina, the protein from embryonic chicks was purified and characterized. The tissue distribution of this protein in embryonic and hatched chicks was determined using polyclonal ant...
متن کاملEnterocyte fatty acid uptake and intestinal fatty acid-binding protein.
This article reviews our current understanding of the uptake of fatty acids by the enterocytes of the intestine. The micellar solubilization of fatty acids by bile salts and the factors regulating that process are discussed. The mechanism of how micellar solubilization of fatty acids promotes the uptake of fatty acids by enterocytes and their relative importance is reviewed. Additionally, discu...
متن کاملProtein-mediated Fatty Acid Uptake in the Heart
Long chain fatty acids (LCFAs) provide 70-80% of the energy for cardiac contractile activity. LCFAs are also essential for many other cellular functions, such as transcriptional regulation of proteins involved in lipid metabolism, modulation of intracellular signalling pathways, and as substrates for membrane constituents. When LCFA uptake exceeds the capacity for their cardiac utilization, the...
متن کاملRequirement for the heart-type fatty acid binding protein in cardiac fatty acid utilization.
Nonenzymatic cytosolic fatty acid binding proteins (FABPs) are abundantly expressed in many animal tissues with high rates of fatty acid metabolism. No physiological role has been demonstrated for any FABP, although these proteins have been implicated in transport of free long-chain fatty acids (LCFAs) and protection against LCFA toxicity. We report here that mice lacking heart-type FABP (H-FAB...
متن کاملHepatic phenotype of liver fatty acid binding protein gene-ablated mice.
Although the function of liver fatty acid binding protein in hepatic fatty acid metabolism has been extensively studied, its potential role in hepatic cholesterol homeostasis is less clear. Although hepatic cholesterol accumulation was initially reported in L-FABP-null female mice, that study was performed with early N2 backcross generation mice. To resolve whether the hepatic cholesterol pheno...
