Fig. 3. Reggie-1 and Src can be coimmunoprecipitated. HeLa cells were transfected with R1-EGFP and Src, Y527F-Src or dead-Src constructs and immunoprecipitation was performed with anti-GFP antibody. Src kinase coprecipitates with R1-EGFP, but the degree of coprecipitation is higher with active forms of Src.
