PLoS ONE, 2019 Vision is very important to fish as it is required for foraging food, fighting competitors, fleeing from predators, and finding potential mates. Vertebrates express opsin genes in photoreceptor cells to receive visual signals, and the variety of light ...

BMC Ecology and Evolution, 2022 Background Visual opsins are expressed in the compound eyes and ocelli of insects and enable light detection. Three distinct phylogenetic groups of visual opsins are found in insects, named long (LW), short (SW) and ultraviolet (UV) wavelength sensitive ...

Opsin Evolution in Flower-Visiting Beetles
Frontiers in Ecology and Evolution, 2021 Flowers have evolved signals that exploit the sensory systems of insect visitors. In the case of visual cues, color signals are thought to have been shaped in large part by the spectral sensitivity of key pollinators, such as hymenopterans.

Vision Research, 2006 Palmitylation is a widespread modification in G-protein-coupled receptors and often a dynamic process. In rhodopsins, palmitylation is static on C322/C323. Red/green (M/LWS) cone opsins have no cysteines at corresponding positions and no palmitylation.

Biochemical and Biophysical Research Communications, 2020 Optogenetics is a biological technique that combines the advantageous spatial-temporal resolution of optics and genetic cell targeting to control cellular activity with unprecedented precision. It has found vast applications both in neurosciences and therapy, particularly in view of its application to restore vision in blind patients.

Gene-based Therapy in a Mouse Model of Blue Cone Monochromacy
Scientific Reports, 2017 Cones are responsible for daylight, central, high acuity and color vision. Three proteins found in human cones, i.e. long-wavelength (L)-, middle-wavelength (M)-, and short-wavelength sensitive (S)-opsins, are responsible for red, green and blue color ...

High-Level Inducible Expression of Visual Pigments in Transfected Cells
BioTechniques, 1996 A method for high-level expression of a functionally active, recombinant human red cone opsin was developed by adding the coding sequence for the C-terminal epitope of bovine rhodopsin onto the C terminus of the cone opsin and cloning the resulting ...

Ciliary Transport of Opsin [PDF]
, 2009 As part of the renewal of photoreceptor outer segment disk membranes, membrane proteins are transported along the region of the cilium, connecting the inner and outer segments. Genetics studies have indicated the role of motor proteins in this transport.

The evolution of opsin genes in five species of mirid bugs: duplication of long-wavelength opsins and loss of blue-sensitive opsins [PDF]
BMC Ecology and Evolution, 2021 AbstractBackgroundColor vision and phototactic behavior based on opsins are important for the fitness of insects because of their roles in foraging and mate choice. Related topics, including the duplication and loss of opsin genes, have been well investigated in insect orders such as Coleoptera, Lepidoptera, Hymenoptera, Odonata and Orthoptera, and the
