The interaction of human plasma retinol-binding protein with plasma prealbumin was studied by the techniques of velocity ultracentrifugation and polarization of retinol fluorescence. In the first method the unbound fraction of retinol-binding protein, which sediments more slowly than its complexes with prealbumin, was measured by its absorption. A stoichiometry of retinol-binding protein to pre...
Human small intestine was found to contain a retinol-binding protein similar to the gut-specific cellular retinol-binding protein, type two [CRBP (II)], described in the rat. This newly detected human protein was immunochemically distinct from human cellular retinol binding protein previously described but immunochemically similar to rat CRBP (II). The partially purified protein bound retinol a...
Specific cellular binding proteins for retinol and retinoic acid from mammalian and avian species may mediate the action of retinoids in the control of epithelial differentiation, growth and tumorigenesis. Parasite retinol-binding protein (PRBP) and parasite retinoic acid-binding protein (PRABP) isolated and characterized from parasitic worms of the family Filarioidea might be involved in some ...
The stellate cells of the liver are the main storage site of retinyl esters in the body. During cultivation in vitro of stellate cells isolated from rat and rabbit livers were observed that the cells rapidly loose their retinyl ester content. Freshly isolated stellate cells contain about 144 nmol of total retinol/mg of protein, while cells cultivated for 14 days contained below 0.1 nmol/mg of p...
PURPOSE Interphotoreceptor retinoid-binding protein(IRBP) is a four-repeat protein found in the interphotoreceptor space. Each repeat can bind retinoids and fatty acids. The purpose of this study was to examine the effects of the single amino acid substitution, G239T, versus the wild type sequence of human IRBP Repeat 1, on ligand binding at equilibrium, ligand off rates, and protection of reti...
Recently we reported on the dynamic properties of the cellular retinol binding protein, a member of the fatty acid binding protein family. A few conserved glycines were identified as important for producing the conformational changes necessary for the uptake and release of retinol. Here, we describe a multidisciplinary analysis of a genetically engineered mutation of one of these glycines (Gly6...
the established risk factors for cardiometabolic disease. However, the alarming increase in overweight and obesity in children and the trajectory and reach of related comorbidities such as cardiometabolic disease challenge us to identify potential modifiable pathways that will have sufficient impact to turn these around. In this context, this study is a step in the direction of identifying uniq...
