Eye Development in Sepia officinalis Embryo: What the Uncommon Gene Expression Profiles Tell Us about Eye Evolution

Frontiers in Physiology, 2017
In metazoans, there is a remarkable diversity of photosensitive structures; their shapes, physiology, optical properties, and development are different.

Transducin inhibition of light-dependent rhodopsin phosphorylation: evidence for beta gamma subunit interaction with rhodopsin

, 2014
Rhodopsin kinase was purified from bovine retina rod outer segments as a 62-64-kDa protein that phosphorylated purified rhodopsin reconstituted into egg phosphatidylcholine/phosphatidylethanolamine liposomes.

Circadian rhythms in the Drosophila eye may regulate adaptation of vision to light intensity

Frontiers in Neuroscience
The sensitivity of the eye at night would lead to complete saturation of the eye during the day. Therefore, the sensitivity of the eye must be down-regulated during the day to maintain visual acuity.

Lipid−Rhodopsin Hydrophobic Mismatch Alters Rhodopsin Helical Content

, 2016
The ability of photoactivated rhodopsin to achieve the enzymatically active metarhodopsin II conformation is exquisitely sensitive to bilayer hydrophobic thickness.

Allele-Specific Inhibition of Rhodopsin With an Antisense Oligonucleotide Slows Photoreceptor Cell DegenerationAllele-Specific Inhibition of Rhodopsin for adRP [PDF]

, 2015
PURPOSE: To preserve photoreceptor cell structure and function in a rodent model of retinitis pigmentosa with P23H rhodopsin by selective inhibition of the mutant rhodopsin allele using a second generation antisense oligonucleotide (ASO).

Mutant dominant-negative rhodopsin∆I256 causes protein aggregates degraded via ERAD and prevents normal rhodopsin from proper membrane trafficking

Frontiers in Molecular Biosciences
Dominant mutations in the rhodopsin gene (Rho) contribute to 25% of autosomal dominant retinitis pigmentosa (adRP), characterized by photoreceptor loss and progressive blindness. One such mutation, Rho∆I256, carries a 3-bp deletion, resulting in the loss

A key amino acid site associated with rhodopsin mammal evolution to diurnal vision

Scientific Reports
Rhodopsin is a photoreceptor protein found in the vertebrate retina used as a landmark for vision evolution studies at the molecular level. Here, we examined the biochemical and functional performance of modern rhodopsin from three different mammal ...

Shine Amidst Darkness—A Case of Oguchi Disease

TNOA Journal of Ophthalmic Science and Research
An 11-year-old boy presented with complaints of defective night vision. Visual acuity was 6/6 in both eyes. The fundus showed a golden-to-grey discoloration in light and on dark adaptation, the fundus reverted to its normal appearance demonstrating the ...
