Drosophila opsin genes

In a recent study, Zeng et al. (1994) showed that the overexpression of PER in photoreceptor cells in Drosophila eyes suppresses circadian rhythms in these cells, but not in other per-expressing cells located in the brain. The experiment was performed by means of a construct containing the promoter region of the Drosophila opsin gene followed by a fragment of per.
