Figure 1. FBXO22 interacts with KLF4 in vivo.
A. HepG2Cells were transfected with adenovirus expressing Flag-KLF4 or empty vector for 36 hr. The pull-down products from Flag M2 beads affinity purification were separated by SDS-polyacrylamide gel electrophoresis (SDS-PAGE), visualized by Colloidal blue staining, and analyzed by mass spectrometry. The identified SCFFBXO22 components are listed. B–C. Endogenous association between FBXO22 and KLF4 in HepG2 cells was performed by co-immunoprecipitation (CO-IP) experiments. D. The interaction of FBXO22 and KLF4 in cells depleted with KLF4. HepG2 cells were administered with adenoviral shRNA targeting KLF4 or a negative control (NC)
