Page 7321, Fig. 5D: The bottom two Western blot panels (RTA-FLAG and orf36-FLAG) were duplicated in order to place the bands in closer proximity to show expression of FLAG-tagged proteins. In the process of cropping and realigning the images, the bottom panel (orf36-FLAG) was inadvertently horizontally reflected. We have corrected this error by removing these duplicated panels and displaying the original uncropped blot.
The bottom blot of Fig. 5D should appear as shown below.
These changes do not affect the conclusions of the paper.
