Figure 3. Residues 33K-64Q are important for the interaction between BEX1 and BCL-2.

Figure 3

A, Schematic representations of HA-tagged BEX1 deletion mutants and their ability to bind to BCL-2. B–D, HEK293 cells were transfected with plasmids expressing HA-BEX1 and HA-tagged BEX1 deletion mutants. BEX1 was immunoprecipitated using an anti-HA antibody, and the co-immunoprecipitate (co-IP) was analyzed by immunoblotting with an anti-BCL-2 antibody. BCL-2 was immunoprecipitated using an anti-BCL-2 antibody or isotype control rabbit IgG, and the co-IP was analyzed by IB with an anti-HA antibody. The presence of HA-BEX1, HA-tagged BEX1 deletion mutants and BCL-2 were monitored in the WCE.
