Binding of retinol induces changes in rat cellular retinol-binding protein II conformation and backbone dynamics.
The structure and backbone dynamics of rat holo cellular retinol-binding protein II (holo-CRBP II) in solution has been determined by multidimensional NMR. The final structure ensemble was based on 3980 distance and 30 dihedral angle restraints, and was calculated using metric matrix distance geometry with pairwise Gaussian metrization followed by simulated annealing. The average RMS deviation ...
متن کاملLocalization of cellular retinol-binding protein in several rat tissues.
The distribution of cellular retinol-binding protein (CRBP) in rat liver, ileum, and epididymis was examined by the peroxidase-antiperoxidase immunolocalization technique. Positive cytoplasmic staining was seen in the liver when antiserum prepared against purified CRBP was used but not when antiserum absorbed with purified CRBP was used. Ileal mucosa, a tissue that contains no detectable CRBP, ...
متن کاملTransfer of retinol-binding protein from HepG2 human hepatoma cells to cocultured rat stellate cells.
Rat liver stellate cells were cocultured with HepG2 human hepatoma cells, which are known to synthesize and secrete retinol-binding protein (RBP). Transfer of human RBP from HepG2 cells to stellate cells was studied by cryoimmunoelectron microscopy. In stellate cells, human RBP was found on the cell surface and within endosomes. The transfer of human RBP from HepG2 cells to stellate cells was b...
متن کاملColchicine inhibition of retinol-binding protein secretion by rat liver.
Studies were conducted to explore the effects of colchicine on the secretion and metabolism of retinol-binding protein (RBP) by the liver. In the vitamin A-deficient rat, the rate of secretion of RBP from the liver into the serum is greatly reduced, and RBP accumulates in the liver. Injection of retinol (dispersed in a 20% Tween 40 solution) into deficient rats stimulated a rapid secretion of R...
متن کاملLocalization of cellular retinol-binding protein and retinol-binding protein in cells comprising the blood-brain barrier of rat and human.
Brain is not generally recognized as an organ that requires vitamin A, perhaps because no obvious histologic lesions have been observed in severely vitamin A-deficient animals. However, brain tissue does contain cellular vitamin A-binding proteins and a nuclear receptor protein for retinoic acid. In the present study, immunohistochemical techniques were used to determine the cell-specific locat...
