NUP98-HOXA9 and NUP98-DDX10 co-immunoprecipitate with endogenous CRM1. A, K562 cells were nucleofected with either empty pcDNA3 vector (Control) or vector expressing FLAG-tagged NUP98-HOXA9 or NUP98-DDX10. Anti-NUP98 immunoblot of nuclear lysates shows the transduced fusion proteins as well as endogenous NUP98. B, nuclear lysates and immunoprecipitates (IP) prepared using anti-FLAG antibody from control cells or cells expressing the indicated FLAG-tagged NUP98 fusions were analyzed by anti-CRM1 immunoblotting.
