Figure 3. A portion of G51R rhodopsin is transported to the lysosomes in the absence of Rer1p.
(A) Translocation of G51R mutant rhodopsin to lysosomes in Rer1 knockdown cells. HeLa cells expressing each FLAG-rhodopsin-GFP construct were transfected with control siRNA or Rer1 #2 siRNA. Cells were immunostained with an anti-LAMP1 antibody. The signals of FLAG-rhodopsin-GFP (green) and LAMP-1 (red) are shown in the merged images. Bar: 10 μm. (B) The graph shows the average number of rhodopsin-positive puncta per cell. Thirty cells were counted in each experiment. Three independent experiments were examined. Error bars represent the SE. * indicates p < 0.05.
