A Large and Phylogenetically Diverse Class of Type 1 Opsins Lacking a Canonical Retinal Binding Site. [PDF]
PLoS ONE, 2016 Opsins are photosensitive proteins catalyzing light-dependent processes across the tree of life. For both microbial (type 1) and metazoan (type 2) opsins, photosensing depends upon covalent interaction between a retinal chromophore and a conserved lysine

Evolutionary Constraint on Visual and Nonvisual Mammalian Opsins
Journal of Biological Rhythms, 2021 Animals have evolved light-sensitive G protein–coupled receptors, known as opsins, to detect coherent and ambient light for visual and nonvisual functions.

Enhancer/promoter activities of the long/middle wavelength-sensitive opsins of vertebrates mediated by thyroid hormone receptor β2 and COUP-TFII. [PDF]
PLoS ONE, 2013 Cone photopigments (opsins) are crucial elements of, and the first detection module in, color vision. Individual opsins have different wavelength sensitivity patterns, and the temporal and spatial expression patterns of opsins are unique and stringently ...

From the Sea for the Sight: Marine Derived Products for Human Vision
Frontiers in Aging Neuroscience, 2022 Visual impairment, at different degrees, produce a reduction of patient wellness which negatively impact in many aspects of working and social activities. Eye diseases can have common cellular damages or dysfunctions (e.g., inflammation, oxidative stress,

Diversity of Active States in TMT Opsins. [PDF]
PLoS ONE, 2015 Opn3/TMT opsins belong to one of the opsin groups with vertebrate visual and non-visual opsins, and are widely distributed in eyes, brains and other internal organs in various vertebrates and invertebrates.

The First Opsins Prediction in Achatina fulica Genome
Biology and Life Sciences Forum, 2022 The variety of spectral properties of visual pigments is provided mainly by the amino acid sequences of their protein component, the so-called visual opsins.

Genetic Constructs for the Control of Astrocytes’ Activity
Cells, 2021 In the current review, we aim to discuss the principles and the perspectives of using the genetic constructs based on AAV vectors to regulate astrocytes’ activity.
