We previously characterized five visual opsin genes of American chameleon (Anolis carolinensis). Here we report its nonvisual opsin gene orthologous to the chicken pineal gland-specific opsin (p-opsin) gene. In the pure-cone American chameleon retina, all visual opsins including rod opsin are expressed. In both pineal and parietal eye, three visual opsins as well as P-opsin are expressed. Although opsins are detected in the pineal glands of a wide variety of vertebrates, Southern analysis suggests that the P-opsin gene is used mainly by birds and reptiles.
我们之前鉴定了美国变色龙（安乐蜥）的五个视觉视蛋白基因。在此，我们报告了其与鸡松果体特异性视蛋白（p-视蛋白）基因直系同源的非视觉视蛋白基因。在纯锥状细胞的美国变色龙视网膜中，包括视杆视蛋白在内的所有视觉视蛋白均有表达。在松果体和顶眼中，三种视觉视蛋白以及P-视蛋白均有表达。尽管在多种脊椎动物的松果体中都检测到了视蛋白，但Southern分析表明，P-视蛋白基因主要为鸟类和爬行动物所使用。
