Protanopia (red color-blindness) in medaka: a simple system for producing color-blind fish and testing their spectral sensitivity [PDF]
, 2017 BACKGROUND: Color perception is important for fish to survive and reproduce in nature. Visual pigments in the retinal photoreceptor cells are responsible for receiving light stimuli, but the function of the pigments in vivo has not been directly ...

Adaptive genomic evolution of opsins reveals that early mammals flourished in nocturnal environments
BMC Genomics, 2018 Background Based on evolutionary patterns of the vertebrate eye, Walls (1942) hypothesized that early placental mammals evolved primarily in nocturnal habitats. However, not only Eutheria, but all mammals show photic characteristics (i.e.

Functional characterization of the rod visual pigment of the echidna (Tachyglossus aculeatus), a basal mammal [PDF]
, 2017 Monotremes are the most basal egg-laying mammals comprised of two extant genera, which are largely nocturnal. Visual pigments, the first step in the sensory transduction cascade in photoreceptors of the eye, have been examined in a variety of vertebrates,

Spatially differentiated expression of quadruplicated green-sensitive RH2 opsin genes in zebrafish is determined by proximal regulatory regions and gene order to the locus control region [PDF]
, 2015 BACKGROUND: Fish are remarkably diverse in repertoires of visual opsins by gene duplications. Differentiation of their spatiotemporal expression patterns and absorption spectra enables fine-tuning of feature detection in spectrally distinct regions of ...

Flavonoid allosteric modulation of mutated visual rhodopsin associated with retinitis pigmentosa [PDF]
, 2017 Dietary flavonoids exhibit many biologically-relevant functions and can potentially have beneficial effects in the treatment of pathological conditions. In spite of its well known antioxidant properties, scarce structural information is available on the ...

The appearance of rod opsin during monkey retinal development.
Investigative ophthalmology & visual science, 1996 To determine the temporal and spatial pattern of rod opsin appearance in Macaca monkey retina.Frozen sections from fetal day (Fd) 55 to adulthood (birth = Fd168) containing the entire horizontal meridian were stained using Rho4D2 monoclonal antiserum visualized with immunofluorescent labeling.

The mammalian cone visual cycle promotes rapid M/L-cone pigment regeneration independently of the interphotoreceptor retinoid-binding protein [PDF]
, 2011 Rapid regeneration of the visual pigment following its photoactivation is critical for the function of cone photoreceptors throughout the day. Though the reactions of the visual cycle in the retinal pigment epithelium (RPE) that recycle chromophore for ...
