FIGURE 3.

Interaction between Arr1-eGFP and Rh1 in live photoreceptors. Subcellular localization of Arr1-eGFP in flies expressing wild type (A) and Rh1Δ356 (B). C, subcellular distribution of Arr2-eGFP in wild-type photoreceptors. D, a comparison of the REI between Arr2-eGFP (gray) or Arr1-eGFP (black) in wild-type (wt) or mutant Rh1 backgrounds. The genotype for S>A is Rh1CT S>A; ninaE⁷. Data are represented as the mean ± S.E. (n = 5). ***, p < 0.001 when compared with the value obtained in the wild-type background. All images were taken after at least 4 min of blue light exposure.
