Abstract:
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.
