Sequences and evolution of human and squirrel monkey blue opsin genes.
The one statistically significant difference identified here supports the principle that the nucleotide differences in the region of the opsin genes are responsible for determining cone ratio.
One significant difference between the transgene and the endogenous opsingene is the implicit onset of opsin expression.
We therefore chose three earlier time points to detect changes in opsingene expression that are involved in this process.
We are now focusing our efforts on identifying transcription factor binding sites on opsingene promoters that are responsible for differential patterns of expression.
The process of light-driven shedding may also influence opsingene expression.
The retina of the rainbow trout is a useful model to study developmental changes in opsingene expression.
When the same viral constructs are used to deliver a human long-wavelength opsingene to gerbil cones, stimulation of the introduced human photopigment with long-wavelength light produces robust cone responses.
Spatio-temporal characterization of retinal opsingene expression during thyroid hormone-induced and natural development of rainbow trout.
Isolation and analysis of the mouse opsingene.
The similarities among the four opsin genes we identified extend to gene structure.
Radial cryosections of juvenile retina were used to determine the expression patterns of the cloned opsin genes.
Two more opsin genes were identified with this approach, namely red and blue opsins.
This low-sequence similarity and the high stringency in the in situ hybridization procedure make it unlikely that cross hybridization between the different opsin genes occur.
