Figure 2. Ectopically-expressed RasGAP and G3BP1 fail to interact in conditions where RasGAP binds to RhoGAP.
Lysates (1 mg) from HEK293T cells that had been transfected with the indicated plasmids were immunoprecipitated with an anti-V5 antibody. Immunoprecipitated complexes and cell lysates (50 µg) were analyzed by Western blotting using HA- and V5-specific antibodies. Asterisks: non-specific bands; #: immunoglobulin heavy chains; white arrowhead: expected migration of HA-G3BP1.
