Fig. 9. The translocation of DGqα is independent of PLC and downstream signaling. In the absence of PLC (in the norpA^P24 mutant), the initial kinetics of DGqα translocation to the cytosol (diamonds) are very similar to those of wild-type flies (squares). Differences emerge only after prolonged illumination, resulting in translocation that proceeds almost to completion. The graph shows the mean amount of DGqα in the supernatant (as a percentage of total) ± SE from five independent experiments. The graph of wild-type flies is identical to Figure 1A and is shown for comparison.
