Volume 9, no. 6, e02377-18, 2018, https://doi.org/10.1128/mBio.02377-18. In Fig. 2B, we made a mistake in the assembly of the panels such that the images for the cells grown in LIM were used in both the panel labeled LIM and the panel labeled LIM + 100 µM heme. A new version of Fig. 2 has been prepared to show the correct images for the cells from the LIM + 100 µM heme condition. This mistake in figure preparation does not change any of the interpretations or conclusions in our paper. The Cir1-GFP fusion protein is located in the nucleus under all conditions. We apologize for any inconvenience.
