Fig. 3. PP4 RNAi elevates the Hh-induced Smo cell-surface accumulation.
(A-P) CFP-tagged Smo constructs were transfected into S2 cells and
treated with phosphatase inhibitor (OA), phosphatase dsRNA or Hh-conditioned
medium. Cell-surface-localized Smo was visualized by immunostaining with
anti-SmoN antibody. The total amount of expressed Smo was indicated by the CFP
signal. (Q) Ratio of cell surface level to total level of Smo. Each
data set was based on 15 individual cells. WT, CFP-Smo; SD123, CFP-SmoSD123;
626-678, CFP-Smo
626-678.
