Photoreceptors for a light biotransducer: a comparative study of the electrical responses of two (type-1)-opsins [PDF]

open access: yesNanotechnology, 24, 39551 (2013), 2013
The increasing interest in photoactivated proteins as natural replacement of standard inorganic materials in photocells drives to the compared analysis of bacteriorhodopsin and proteorhodopsin, two widely diffused proteins belonging to the family of ...

Adaptations of the Vertebrate Retina to Low-Light Conditions: A Review. [PDF]

open access: yesAnat Histol Embryol
ABSTRACT Vision is a critical sensory modality in vertebrates, enabling diverse adaptations to environmental challenges. This review explores the remarkable adaptations of vertebrate eyes to low‐light environments, such as nocturnal habitats, deep‐sea ecosystems and subterranean niches.

Retention of duplicated long-wavelength opsins in mosquito lineages by positive selection and differential expression [PDF]

open access: yesBMC Evolutionary Biology, 2017
BACKGROUND: Opsins are light sensitive receptors associated with visual processes. Insects typically possess opsins that are stimulated by ultraviolet, short and long wavelength (LW) radiation.

An Expanding Role for Nonvisual Opsins in Extraocular Light Sensing Physiology.

open access: yesAnnual Review of Vision Science, 2023
We live on a planet that is bathed in daily and seasonal sunlight cycles. In this context, terrestrial life forms have evolved mechanisms that directly harness light energy (plants) or decode light information for adaptive advantage. In animals, the main

Multiple opsins in a reef-building coral, Acropora millepora

open access: yesScientific Reports, 2023
Opsins, light-sensitive G protein-coupled receptors, have been identified in corals but their properties are largely unknown. Here, we identified six opsin genes (acropsins 1–6) from a coral species Acropora millepora , including three novel opsins ...

Molecular advances to study the function, evolution and spectral tuning of arthropod visual opsins

open access: yesPhilosophical Transactions of the Royal Society of London. Biological Sciences, 2022
Visual opsins of vertebrates and invertebrates diversified independently and converged to detect ultraviolet to long wavelengths (LW) of green or red light.

Insect opsins and evo-devo: what have we learned in 25 years?

open access: yesPhilosophical Transactions of the Royal Society of London. Biological Sciences, 2022
The visual pigments known as opsins are the primary molecular basis for colour vision in animals. Insects are among the most diverse of animal groups and their visual systems reflect a variety of life histories.

Creation of photocyclic vertebrate rhodopsin by single amino acid substitution

open access: yeseLife, 2022
Opsins are universal photoreceptive proteins in animals and can be classified into three types based on their photoreaction properties. Upon light irradiation, vertebrate rhodopsin forms a metastable active state, which cannot revert back to the original

High performance microbial opsins for spatially and temporally precise perturbations of large neuronal networks

open access: yesbioRxiv, 2021
Patterned optogenetic activation of defined neuronal populations in the intact brain can reveal fundamental aspects of the neural codes of perception and behavior.
