Rod monochromacy and the coevolution of cetacean retinal opsins. [PDF]

open access: goldPLoS Genetics, 2013
Cetaceans have a long history of commitment to a fully aquatic lifestyle that extends back to the Eocene. Extant species have evolved a spectacular array of adaptations in conjunction with their deployment into a diverse array of aquatic habitats ...

Discovery and design of photocyclic animal opsins: potential application to gene therapy from non-visual opsin research [PDF]

open access: yesEye and Vision
Opsins are universal photoreceptive proteins in animals. Rhodopsin is the best-studied opsin and functions as a visual sensor in rod cells of human and mouse retinas.

Light intensity and opsin sensitivity shape the morphology of cone photoreceptor outer segments. [PDF]

open access: yesPLoS Biology
Regulation of neural cell morphology remains a fundamental question in neuroscience. Photoreceptor cells, a specialized class of neurons capable of initiating the phototransduction cascade, exhibit distinct structural and morphological characteristics ...

Two genes, one culprit - a functional candidate validation of a SPATA7 deletion in dogs with day blindness/retinal degeneration. [PDF]

open access: yesPLoS Genetics
Inherited retinal diseases (IRDs) are a diverse group of disorders that share common vision deficits ranging from early onset blindness to severe and progressive later-onset disease. We report a form of early-onset day-vision loss, cone-rod dystrophy, in

Syntaxin 3B Mediates Light‐Dependent Interactions with STXBP1 and Arrestin 4: Distinct Roles in Rods and Cones [PDF]

open access: yesAdvanced Science
Syntaxin 3 (STX3), a member of the soluble N‐ethylmaleimide‐sensitive factor attachment protein receptor (SNARE) family, plays a central role in vesicle fusion.

From Embryo to Adult Life: Differential Expression of Visual Opsins in the Flatfish Solea senegalensis Under Different Light Spectra and Photoperiods

open access: yesFrontiers in Marine Science, 2022
Visual photoreceptors in fish are usually adjusted to the light environment to ensure the highest efficiency and best adaptation. In the Senegalese sole, metamorphosis determines migration from pelagic to benthic habitats, with marked differences in both

Opsins as main regulators of skin biology

open access: yesJournal of Photochemistry and Photobiology, 2023
Opsins are light-sensitive proteins that are found across the animal kingdom. In mammals, opsins are classically associated with image-forming processes, a function exerted by cone and rod opsins.

Spectral tuning and deactivation kinetics of marine mammal melanopsins

open access: yesPLoS ONE, 2021
In mammals, the photopigment melanopsin (Opn4) is found in a subset of retinal ganglion cells that serve light detection for circadian photoentrainment and pupil constriction (i.e., mydriasis).

TMT-Opsins differentially modulate medaka brain function in a context-dependent manner.

open access: yesPLoS Biology, 2021
Vertebrate behavior is strongly influenced by light. Light receptors, encoded by functional opsin proteins, are present inside the vertebrate brain and peripheral tissues.
