The Rhodopsin-retinochrome system is essential for the visual photoreception of molluscs. cDNA coding for retinochrome of the squid (Todarodes pacificus) was cloned and the nucleotide sequence has been determined. The sequence (2.1 kb) covers the whole coding region of 903 bp. The deduced primary sequence suggests that retinochrome contains seven transmembrane spanning domains. The homology with bovine rhodopsin and the possible retinal binding site are also discussed.
视紫红质-视黄醛色素系统对于软体动物的视觉光感受至关重要。克隆了编码鱿鱼（太平洋褶柔鱼）视黄醛色素的cDNA，并确定了其核苷酸序列。该序列（2.1 kb）覆盖了903 bp的整个编码区域。推导的一级序列表明视黄醛色素含有七个跨膜结构域。还讨论了与牛视紫红质的同源性以及可能的视黄醛结合位点。
