Abstract
- Visual opsins coupled with Gq -type G protein have been considered to be responsible for the vision in mollusks. Recent transcriptomic studies, however, revealed the presence of opsin mRNA belonging to different groups of opsin subfamilies in the eyes of mollusks. In the present study, we found that at least three different opsins, Gq -coupled rhodopsin, opsin5A, and xenopsin, are co-expressed in the rhabdomeric photoreceptor cell in the eyes of the terrestrial slug Limax valentianus. These opsins were all localized to the microvilli of the rhabdomere. Co-expression of rhodopsin and opsin5A mRNA was also demonstrated by dual fluorescence in situ hybridization. Co-expression of multiple opsins in the rhabdomeric photoreceptors cells may explain the previously reported shift in the action spectra of the electroretinogram of eyes of Limax flavus between the light- and dark-adapted states, which was also reproduced in the present study in L. valentianus.
