1
Visual sensitivity can be tuned by differential expression of opsin genes.
2
Alternatively opsin can be activated by incubation of oocytes with all-trans-retinal.
3
Limited data on X-linked opsin variation in lemurs make such hypotheses difficult to evaluate.
4
The analogues apparently relieve a stable component of adaptation when they interact with opsin.
5
This rapid degeneration suggests that nonpalmitoylated rod opsin is unstable.
1
Similar results were obtained with expressed human red and green opsins.
2
Animals have specialised proteins called opsins that respond to light.
3
Here we tested the hypothesis that nonvisual opsins mediate photorelaxation in the pulmonary circulation.
4
Wedged into their surfaces are proteins called opsins.
5
In contrast, 11-cis-retinol activates the expressed salamander and human red rod opsins, acting as an agonist.
6
He and Oakley found that the genes coding for opsins were activated in the octopus skin.
7
We report here the first-characterized cnidarian opsins.
8
Those pigments are composed of photoreceptor molecules called opsins, along with a derivative of vitamin A called retinol.
9
In addition to a standard panel of stains, tissues were immunostained against a variety of rod and cone opsins.
10
Further, opsins likely duplicated and were lost many times, with different lineages of animals maintaining different repertoires of opsin paralogs.
11
Physiological studies showed that visible light-sensitive photoreceptors are also present in median ocelli, but the visible light-sensitive opsins they express were unknown.
12
Optogenetics requires implantation of light-delivering optical fibers, as current light-sensitive opsins are activated by visible light, which cannot effectively penetrate biological tissues.
13
Color discrimination in the vertebrate retina is mediated by a combination of spectrally distinct cone photoreceptors, each expressing one of multiple cone opsins.
14
Optogenetics is a transformative technology based on light-sensitive microbial proteins, known as opsins, that enable precise modulation of neuronal activity with pulsed radiant energy.
15
Currently prevalent GEVIs are based on the voltage-sensitive fluorescent protein (VSFP) prototypical design or on the voltage-dependent state transitions of microbial opsins.
16
Analysis of the conversation of residues in the extracellular portion of TM1 of opsins showed a pattern consistent with alpha-helical structure with a conserved face.
