A cDNA fragment encoding a putative visual pigment (FCV pigment) was isolated from the bullfrog, Rana catesbeiana. Its deduced amino acid sequence shows high similarities to those of short wavelength-sensitive pigments such as human blue-, chicken violet- and goldfish ultraviolet-sensitive pigments. An antiserum against its C-terminal amino acid sequence recognized the outer segments of small cone photoreceptor cells without oil droplets. It is suggested that the FCV pigment is a short wavelength-sensitive pigment contained in small single cones which have not been characterized previously.
从牛蛙（Rana catesbeiana）中分离出一个编码假定视觉色素（FCV色素）的cDNA片段。其推导的氨基酸序列与短波敏感色素（如人类蓝色色素、鸡紫色色素和金鱼紫外线敏感色素）的氨基酸序列高度相似。针对其C端氨基酸序列的抗血清识别无油滴的小视锥光感受器细胞的外段。这表明FCV色素是一种存在于此前未被鉴定的小单视锥细胞中的短波敏感色素。
