(B) Bim bridges the Beclin 1-LC8 interaction. Dynein light chain1 (Myc-LC8)/empty vectors (IP negative control), Myc-LC8/Beclin 1-Flag/empty vector, Myc-LC8/Beclin 1-Flag/BimEL-EE (EL), Myc-LC8/Beclin 1-Flag/BimL-EE (L), Myc-LC8/Beclin 1-Flag/BimS-EE (S), and Myc-LC8/Beclin 1-Flag/BimEL-EE-S109A, S113A, T114A (AAA) were transfected into HeLa cells. Anti-Flag (M2) was used for immunoprecipitation.
