The authors would like to correct an error in Figure 1, which may have inadvertently displayed duplicated and mislabeled figure panels. The corrected Figure 1 is provided with the removal of panels D and F. The text referring to these panels has also been modified in the Results section (pages 1147–1149) and in the figure legend (see below). These corrections do not alter the conclusions of the article. The authors apologize for any confusion.

“The results with these antisera confirmed that α-satellite RNA was enriched in the nucleolus (Fig. 1A,C,D,E). Competition with tRNA and rRNA did not affect the detection of the α-satellite RNA signals at the nucleoli (examples of chromosome 2- and 4-specific α-satellite RNA are shown in Fig. 1G,H).”

“As expected, nucleolin displaced to the nuclear periphery following ActD treatment, whereas UBF1 displayed a typical relocalization toward the nucleolar periphery to give a concentrated cap-like signal at the tip of the nucleoli (Zhang et al. 2004) (Fig. 1Fii). In the presence of the ActD level used, α-satellite RNA also significantly, but not completely, delocalized from the nucleoli, indicating that the nucleolar localization of α-satellite RNA is sensitive to RNA polymerase I inhibition (Fig. 1Biii, Fiii).”

“As controls, parallel experiments were performed to …
