A binding protein for retinal (vitamin A aldehyde), the 11-cis-retinal-binding protein, was present in the soluble protein fraction of rat retina but was absent from brain, lung, heart, skeletal muscle, liver, kidney, spleen, small intestine, and testes. The binding protein was also found in human retina but not human liver. The binding protein for retinal from human retina did not bind retinol and was larger than, and readily separable from, the cellular retinol-binding protein which did not bind retinal. It would appear that the occurrence of a soluble binding protein for retinal, unlike the more widely distributed binding proteins for retinol and retinoic acid, may be unique to the retina.
一种视网膜（维生素A醛）结合蛋白，即11-顺式视网膜结合蛋白，存在于大鼠视网膜的可溶性蛋白组分中，但在脑、肺、心脏、骨骼肌、肝脏、肾脏、脾脏、小肠和睾丸中不存在。该结合蛋白也存在于人类视网膜中，但不存在于人类肝脏中。来自人类视网膜的视网膜结合蛋白不结合视黄醇，且比不结合视网膜的细胞视黄醇结合蛋白更大，并且易于与之分离。看来，视网膜可溶性结合蛋白的存在，与分布更广泛的视黄醇和视黄酸结合蛋白不同，可能是视网膜特有的。
