Interactions of plasma retinol-binding protein with its receptor. Specific binding of bovine and human retinol-binding protein to pigment epithelium cells from bovine eyes.
Bovine and human retinol-retinol-binding protein (RBP) were iodinated to high specific activity. At least 34% of the iodinated material was native and retained its retinol chromophore as judged by its characteristic ability to bind to plasma prealbumin. Bovine and human retinol-125I-RBP were found to bind specifically to intact isolated pigment epithelium cells from bovine eyes. The specific bi...
متن کاملInteraction of the retinol/cellular retinol-binding protein complex with isolated nuclei and nuclear components
Retinol (vitamin A alcohol) is involved in the proper differentiation of epithelia. The mechanism of this involvement is unknown. We have previously reported that purified cellular retinol-binding (CRBP) will mediate specific binding of retinol to nuclei isolated from rat liver. We now report that pure CRBP delivers retinol to the specific nuclear binding sites without itself remaining bound. T...
متن کاملCellular Retinol- and Retinoic Acid-binding Proteins of Bovine Retina
A three-step purification has been developed for the cellular retinoland cellular retinoic acid-binding proteins from extracts of bovine retina. The two binding proteins elute together in Step 1 (gel filtration) and separate in Step 2 (DEAE-cellulose chromatography), and each is purified to apparent homogeneity in the third step (calcium phosphate gel chromatography). The retinoland retinoic ac...
متن کاملBinding 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 کاملRetinol and retinol-binding protein: gut integrity and circulating immunoglobulins.
Vitamin A (retinol) is required to maintain immunity and epithelial turnover and is a key micronutrient needed for combating infection. Vitamin A actions on the immune system are diverse and cannot be accounted for by a single effect or mechanism. The actions of retinol in maintaining gut integrity in humans and immunoglobulin levels in mice was investigated. For 30 children, performance on the...
