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 retinoid binding proteins, retinoid receptors, and retinaldehyde dehydrogenase in the chick eye.
Retinoids have many functions in the eye, including, perhaps, the visual guidance of ocular growth. Therefore, we identified where retinoid receptors, binding proteins, and biosynthetic enzymes are located in the ocular tissues of the chick as a step toward discovering where retinoids are generated and where they act. Using antibodies to interphotoreceptor retinoid binding protein (IRBP), cellu...
متن کاملImmunocytochemical localization of two retinoid-binding proteins in vertebrate retina
The recent discovery and characterization of several proteins that purify with endogenous, bound retinoid have given rise to the suggestion that these proteins, which are abundant in retina, perform a role in transport and function of vitamin A. Immunocytochemical techniques were used to localize two retinoid-binding proteins in the retina of four species. Antisera to cellular retinal-binding p...
