Retinoid-binding proteins: mediators of retinoid action.
Active vitamin A metabolites, known as retinoids, are essential for multiple physiological processes, ranging from vision to embryonic development. These small hydrophobic compounds associate in vivo with soluble proteins that are present in a variety of cells and in particular extracellular compartments, and which bind different types of retinoids with high selectivity and affinity. Traditiona...
متن کاملRetinoid receptors and binding proteins.
Retinoids, in particular all-trans retinoic acid (T-RA), are essential for normal development and homeostasis of vertebrates. Although many effects of retinoids, particularly with regard to teratogenicity, have been described in the literature, the mechanisms by which these simple signalling molecules work has only recently begun to be elucidated. We now recognize at least two classes of retino...
متن کاملRetinoid-binding proteins in cone-dominant retinas.
We identified and localized interphotoreceptor (or interstitial) retinoid-binding protein (IRBP) and cellular retinaldehyde-binding protein (CRALBP) in the cone-dominant retinas of diurnal squirrels. Western blots were prepared from sodium dodecyl sulfate polyacrylamide gels (SDS-PAGE) from whole retina, and from retina proximal and distal to the photoreceptor nuclei. Blots were incubated with ...

متن کاملLocalization of specific retinoid-binding sites and expression of cellular retinoic-acid-binding protein (CRABP) in the early mouse embryo.
Retinoids (vitamin A derivatives) are important for normal embryogenesis and retinoic acid, an acidic derivative of vitamin A, was recently proposed to be an endogenous morphogen. Several retinoids are also potent teratogens. Using an autoradiographic technique, we have identified tissues and cells in early mouse embryos that are able to specifically accumulate a radiolabelled synthetic derivat...
