Opsin Evolution in the Ambulacraria
Marine Genomics, 2015 Opsins--G-protein coupled receptors involved in photoreception--have been extensively studied in the animal kingdom. The present work provides new insights into opsin-based photoreception and photoreceptor cell evolution with a first analysis of opsin sequence data for a major deuterostome clade, the Ambulacraria.

Pineal Opsin: A Nonvisual Opsin Expressed in Chick Pineal
Science, 1995Pineal opsin (P-opsin), an opsin from chick that is highly expressed in pineal but is not detectable in retina, was cloned by the polymerase chain reaction. It is likely that the P-opsin lineage diverged from the retinal opsins early in opsin evolution. The amino acid sequence of P-opsin is 42 to 46 percent identical to that of the retinal opsins.

Evolution of Opsins and Phototransduction [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2009 Opsins are the universal photoreceptor molecules of all visual systems in the animal kingdom. They can change their conformation from a resting state to a signalling state upon light absorption, which activates the G protein, thereby resulting in a signalling cascade that produces physiological responses.

Functions of Opsins in Drosophila Taste [PDF]
Current Biology, 2020 Rhodopsin is a light receptor comprised of an opsin protein and a light-sensitive retinal chromophore. Despite more than a century of scrutiny, there is no evidence that opsins function in chemosensation. Here, we demonstrate that three Drosophila opsins, Rh1, Rh4, and Rh7, are needed in gustatory receptor neurons to sense a plant-derived bitter ...

A Novel and Ancient Vertebrate Opsin [PDF]
FEBS Letters, 1997 We describe the identification of a novel opsin gene isolated from the eyes of Atlantic salmon. The cDNA sequence predicts a protein that has the key features of an opsin, but shows only 32–42% amino acid identity to the known opsin families. Phylogenetic analysis suggests that this opsin is a member of a hitherto unrecognised opsin family that ...
