Fig. 1. Dispersal of ß-COP in cells expressing RGSZ1. HeLa cells were transfected with a plasmid for 6xHis-RGSZ1. The cells were allowed to express RGS proteins for 14 hours, fixed, and then processed for ß-COP staining (a,c). Expressed RGSZ1 was detected with the monoclonal anti-tetra-His antibody (b,d). Arrows indicate RGSZ1-expressing cells with dispersed ß-COP staining. Bar, 20 µm.
