Fig. 2

A, B GP73 interacts with AFP in vivo. A HEK293T cells co-transfected with FLAG-AFP and HA-GP73 were lysed with IP lysis buffer and subjected to immunoprecipitation with anti-HA or anti-FLAG antibodies followed by western blotting with anti-HA or anti-FLAG antibodies. B HepG2 cells were lysed with IP lysis buffer and subjected to immunoprecipitation with anti-AFP or anti-GP73 antibodies followed by western blotting with anti-AFP or anti-GP73 antibodies. C GP73 co-localizes with AFP in cytoplasm. HepG2 cells was stained with GP73 antibody (red) and AFP antibody (green). DAPI (blue), nucleus. Scale bar, 5 µm. D GP73 localizes in the Golgi apparatus. HepG2 cells was stained with GP73 antibody (red) and TGN46 (green). DAPI (blue), nucleus. Scale bar, 5 µm. E GP73 interacts with AFP in vitro. GST pull-down assay was performed by using His-GP73 and GST or GST-AFP proteins in vitro and analyzed by western blotting with anti-His antibody.
