FIGURE 4:

FILIP1, but not WHAMM, is an FLNa-binding protein. (A) Endogenous FLNa from lysed HEK293T cells was precipitated using FILIP1/775-1213 and GST-WHAMM/589-809 in GST pull-down assays. The presence of FLNa in the precipitated material was revealed by Western blotting, using anti-FLNa antibodies. (B–D) Colocalization between FILIP1 or WHAMM and FLNa was revealed by transiently transfecting FLAG-tagged FILIP1 or WHAMM in COS1 cells. FLAG-tagged FILIP1 or WHAMM was visualized with mouse monoclonal anti-FLAG antibodies followed by Alexa Fluor 488–conjugated anti-mouse antibodies. FLNa was visualized using a rabbit anti-FLNa antibody, followed by TRITC-conjugated anti-rabbit antibodies. Scale bar: 20 μm.
