Retinol-Binding Proteins

Vitamins and hormones, 1974
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 ...

Retinol-binding proteins in bovine interphotoreceptor matrix

Biochemical and Biophysical Research Communications, 1982
Summary Interphotoreceptor matrix (IPM) material from bovine eyes contains 1.8 nmoles per eye of vitamin A in light-adapted eyes and 0.7 in dark-adapted eyes, nearly all as unesterified retinol. This constitutes a significant fraction of the vitamin A in the retina-IPM-retinal pigment epithelium functional complex.

Multiple retinol binding proteins in rabbit lung

Biochemical and Biophysical Research Communications, 1974
Summary Rabbit lungs contain components sedimenting on sucrose gradients with a sedimentation coefficient of 2S that bind retinol with high specificity. DEAE-cellulose chromatography following gel filtration reveals the presence of 3 binding components of 17,000, 15,000 and 14,000 daltons respectively, showing different fluorescence spectra.

Porcine retinol binding protein

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1972
Abstract 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, 1975
1. 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.

PLASMA RETINOL‐BINDING PROTEIN*

Annals of the New York Academy of Sciences, 1980
Vitamin 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.
