Two Ago2-binding sites exist in the amino-terminal half of TNRC6B. (A,B,D) SBP pull-down assays of Ago2 and TNRC6B. HEK293F cells were cotransfected with FLAG/SBP or FLAG-tagged Ago2 and the TNRC6B expression vectors. (C) HEK293F cells were cotransfected with FLAG-Ago2 and FLAG-EGFP-TNRC6B or FLAG-EGFP expression vectors as a negative control. (E,F) HEK293F cells were cotransfected with FLAG-Ago2 and wild-type or mutant FLAG/SBP-TNRC6B expression vectors. SBP-pull down assays and Western blotting were performed as shown in Figure 1C.
