Function[RET3_XENLA] IRBP shuttles 11-cis and all trans retinoids between the retinol isomerase in the pigment epithelium and the visual pigments in the photoreceptor cells of the retina. Also involved in the transport of fatty acids and retinal development. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedInterphotoreceptor retinoid binding protein (IRBP), the major soluble component of the interphotoreceptor matrix, is critical to the function, integrity, and development of the vertebrate retina. Although its role is poorly understood, IRBP has been thought to protect 11-cis retinal and all-trans retinol while facilitating their exchange between the photoreceptors and retinal-pigmented epithelium. We determined the X-ray structure of one of the functional units, or modules, of Xenopus laevis IRBP to 1.8 A resolution by multiwavelength anomalous dispersion. The monomeric protein consists of two domains separated by a hydrophobic ligand binding site. A structural homology to the recently solved photosystem II D1 C-terminal-processing protease and the enoyl-CoA isomerase/hydratase family suggests the utility of a common fold used in diverse settings, ranging from proteolysis to fatty acid isomerization to retinoid transport.
