The interactions of retinol with rat cellular retinol-binding protein (CRBP) and with rat serum retinol-binding protein (RBP) were studied. The equilibrium dissociation constants of the two retinol-protein complexes (Kd) were found to be 13 x 10(-9) and 20 x 10(-9) M for CRBP and for RBP, respectively.

The interactions within the molecular complex in which retinol circulates in blood were studied. To monitor binding between retinol-binding protein (RBP) and transthyretin (TTR), TTR was labeled with a long-lived fluorescence probe (pyrene). Changes in the rotational volume of TTR following its association with RBP were monitored by fluorescence ...

Porcine retinol binding protein
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1972Abstract 1. 1. The retinol binding protein (RBP) in porcine serum was partially purified and characterized. 2. 2. Purification was by Cohn fractionation, filtration on Sephadex G-200, chromatography on DEAE Sephadex A-50 and preparative polyacrylamide electrophoresis. 3. 3.

Cellular retinol-binding protein
Biochimica et Biophysica Acta (BBA) - General Subjects, 19751. A protein which binds retinol in vitro with high affinity and specificity was detected by sucrose gradient centrifugation or by gel filtration after preincubating rat tissue cytosols with all-trans-[3H]retinol. This protein sediments in the 2 S region of sucrose gradients.

Expression of retinol‐binding protein and cellular retinol‐binding protein in the bovine ovary
Molecular Reproduction and Development, 2003AbstractRetinol (vitamin A) is essential for reproduction, and retinoids have been suggested to play a role in ovarian steroidogenesis, oocyte maturation, and early embryonic development. Retinol is transported systemically and intercellularly by retinol‐binding protein (RBP).

Studies on the Cellular Uptake of Retinol Binding Protein and Retinol
Experimental Cell Research, 1999The uptake and release of (125)I-RBP and of holoRBP labeled with [(3)H]retinol ((3)H-ROH) were studied in two cell lines which synthesize and secrete RBP, the HepG2 hepatocarcinoma cell line and the Caki-1 kidney adenocarcinoma cell line, and in HeLa cells that do not express the endogenous RBP gene. In all three cell lines a part of endocytosed (125)I-

Aspects of the Metabolism of Retinol-Binding Protein and Retinol
1975Publisher Summary This chapter presents different aspects of the metabolism of retinol-binding protein (RBP) and retinol. RBP is not significantly decreased until the liver reserves of the vitamin are virtually abolished. The diminished concentration of RBP in plasma in manifest vitamin A deficiency reflects the impaired transport of retinol to the ...

PLASMA RETINOL‐BINDING PROTEIN*
Annals of the New York Academy of Sciences, 1980Vitamin A is mobilized from liver stores and transported in plasma in the form of the lipid alcohol retinol, bound to a specific transport protein, retinol-binding protein (RBP). A great deal is known about the chemical structure, metabolism, and biological roles of RBP. RBP is a single polypeptide chain with molecular weight close to 20,000.

Publisher Summary This chapter discusses the methods of isolation, chemical nature, physical properties, biochemistry, and methods of assay of retinol-binding proteins (RBP). The discovery of the importance of vitamin A (retinol) and of the animal in preventing night blindness and maintaining normal growth of the animal body, in replacement of ...

Prealbumin-retinol-binding-protein-retinol complex in hemodialysis patients
The American Journal of Clinical Nutrition, 1988In hemodialysis (HD) patients, serum prealbumin (TBPA) is correlated to nutritional status and outcome despite usually elevated serum levels. The purpose of this work was to study the role of TBPA-retinol-binding-protein (RBP)-retinol complex changes in the elevation of serum TBPA in HD patients.
