KIF23 activated Wnt/β-catenin signaling pathway through direct interaction with Amer1 in gastric cancer

Figure 4. KIF23 directly interacted with Amer1. (A) Examination of KIF23-binding proteins in MGC-803 cells by IP and SDS PAGE gel Coomassie blue staining before using MS assays. (B, C) Coimmunoprecipitation analysis between endogenous Amer1 and KIF23. (D) Coimmunoprecipitation of FLAG-tagged Amer1 with eGFP-tagged KIF23 in 293T cells as indicated. (E) GST-pull down of exogenous Amer1 with KIF23 in MGC-803 cells. GST-NC is the control plasmid of GST-KIF23 and Flag-NC is the control plasmid of Flag-Amer1. Immunofluorescence staining and western blot analysis for the distribution of Amer1 (F) and KIF23 (G). (H) Immunofluorescence images showing the localization of Amer1 in MGC-803 cells after transfection with eGFP-tagged KIF23, FLAG-tagged Amer1, or both.
