<p>(A) Schematic structures of TRIM proteins used in heterodimerization studies. (B) TRIM16 binds MID1. Co-transfection of MID1-GFP and TRIM16-myc-His in HEK293 cells and subsequent immunoprecipitation by anti-myc antibody and Western blot with anti-GFP antibody. (C) MID1 was pulled down via its GFP antibody and a Western blot was performed to detect TRIM16-myc-His in the immunoprecipitated protein complex. (D) Whole cell lysates (WCL) of HEK293 cells transfected with empty vector (EV) or TRIM16-GFP were immunopreciptated with anti-GFP antibody. An anti-PML antibody was used to detect PML as a binding partner of TRIM16. (E) Lysates containing both TRIM16-GFP and TRIM24-His proteins were immunopreciptated with anti-GFP antibody. Anti-His antibody was used to detect the presence of TRIM24 in the TRIM16-associated complex.</p
