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.
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.
6
No correlation was found between these psychophysical measures and the number of M-cone opsin genes.
7
Electrophysiological analysis suggests that VA opsin horizontal cells are intrinsically photosensitive and encode irradiance information.
8
This opsin mutation is located in the second cytoplasmic loop of this G protein-coupled receptor.
9
These experiments provide the first quantitative measurement of opsin activation in physiologically responding mammalian rods.
10
Thus, the kernels of extant opsin diversity arose much earlier in animal history than previously known.
11
This observation was confirmed by coimmunostaining of dissociated retinal cells with the lacZ and opsin antibodies.
12
We have investigated the molecular details of the membrane insertion of the multiple-spanning membrane protein opsin.
13
Among African cichlid fishes, seven cone opsin genes are expressed in different combinations to produce diverse visual sensitivities.
14
A large number of mutations in the opsin gene associated with autosomal dominant retinitis pigmentosa have been identified.
15
Our results suggest that subtle changes in L-cone opsin wavelength absorption may have been adaptive during human evolution.
16
Finally, published opsin sequences of platypus and several other vertebrate species were aligned and compared with immunohistochemical results.
