We used a fluorescently tagged Rab11 because the anti-Rab11 antibodies were not sufficient to label recycling endosomes. However, IFITM3 is detected at native levels and this compromise allowed us to evaluate its localization. Overexpressed IFITM3 was only used for the live cell microscopy shown in the movie, which has now been removed (see reply to reviewer 1).
