本文描述了两个视蛋白的一级结构的短波长吸收视色素推导出的mRNA序列的日本黄燕尾蝶视网膜。氨基酸序列的系统发育分析表明，这些视色素之一是紫外线吸收型，另一个是蓝色吸收型。我们通过组织学原位杂交鉴定了表达这些mRNA的感光细胞。紫外线类型的mRNA在两种不同的感光器类型中表达，这两种感光器类型先前被鉴定为紫外线和紫色受体，这提供了第一个分子生物学证据，即不同类型的光谱受体可能表达具有相同氨基酸序列的视觉色素。蓝色类型的mRNA仅在分类为蓝色受体的细胞中表达。
This paper describes the primary structures of two opsins of short-wavelength-absorbing visual pigments deduced from the mRNA sequences in the retina of the Japanese yellow swallowtail butterfly Papilio xuthus. A phylogenetic analysis of the amino acid sequences indicates that one of these visual pigments is of the ultraviolet-absorbing type and that the other is of the blue-absorbing type. We identified the photoreceptor cells that express these mRNAs by histological in situ hybridization. The mRNA of the ultraviolet type is expressed in two distinct photoreceptor types previously identified as ultraviolet and violet receptors, providing the first molecular biological evidence that different types of spectral receptor probably express a visual pigment with an identical amino acid sequence. The mRNA of the blue type is expressed exclusively in cells classified as blue receptors.
