The sequence of squid (Loligo forbesi) rhodopsin was determined by protein and cDNA sequencing. The protein has close similarity to octopus rhodopsin, having an N-terminal region (residues 1-340) which resembles other guanine-nucleotide-binding protein (G-protein)-linked receptors and a repetitive proline-rich C-terminus (residues 340-452). Comparison of the sequence of squid rhodopsin with those of other members of the G-protein-linked receptor superfamily reveals features which we predict to have both structural and functional importance.
通过蛋白质和cDNA测序确定了鱿鱼(福布斯氏枪乌贼)视紫红质的序列。该蛋白质与章鱼视紫红质有密切的相似性,具有一个N端区域(第1 - 340位氨基酸残基),它类似于其他鸟嘌呤核苷酸结合蛋白(G蛋白)偶联受体,以及一个富含脯氨酸的重复性C端(第340 - 452位氨基酸残基)。将鱿鱼视紫红质的序列与G蛋白偶联受体超家族的其他成员的序列进行比较,揭示了我们预测具有结构和功能重要性的特征。
