The ER lumen marker BiP–sfGFP–HDEL colocalizes with the ER membrane marker tdTomato–Sec61β. Third-instar larval motor nerve terminals from segment A2 muscle 4. (A–C) Representative confocal z-projections showing the plasma membrane marker myr::tdTomato (A), the ER marker BiP–sfGFP–HDEL (B) and the merged signals (C). (D–F) z-projections showing the ER membrane marker tdTomato–Sec61β (D), the ER lumen marker BiP–sfGFP–HDEL (E) and the merged signals (F). All transgenes were driven by the motor neuron driver OK371-Gal4. Scale bars: 5 µm.
