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.

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.

Serum Retinol and Retinol-Binding Protein in Mothers and Infants at Delivery
Biology of the Neonate, 2009The relations at birth between infant and maternal serum retinol, retinol-binding protein (RBP) and retinol/RBP molar ratio were investigated in 25 healthy term infants and their mothers. The mean serum levels of retinol and RBP were significantly higher in the mothers, but the mean molar ratio of retinol/RBP (RBP saturation) was significantly higher ...

Abstract Fluorescence excitation and emission spectra were recorded for human plasma retinol-binding protein and for the complex of retinol-binding protein and prealbumin. The spectra were compared with the fluorescence spectra of retinol in solution in seven different organic solvents.

Scandinavian journal of clinical and laboratory investigation. Supplementum, 1981
Vitamin A is transported from its storage site in the liver to the epithelial tissues by a carrier protein, the Retinol-binding protein (RBP). In plasma RBP forms a complex with thyroxine-binding prealbumin. The present article reviews available data on the RBP system. The complete primary structure of RBP has been determined.
