Correction to: Nature, published online 01 June 2011.

In Figs. 3e, g and 5a of this Article, some of the western blot panels were improperly processed by overexposure. The corrected figure panels, which are properly processed from the original files to preserve fainter signals, are shown as Figs. 1 and 2 to this Amendment, respectively. In addition, incorrect blots were used for the H2A.Z and actin western blot panels in Supplementary Fig. 16; see Supplementary Information to this Amendment for the corrected figure, in which the panels are properly processed to correct for overexposure. The uncropped blots of the original Figs. 3e, g, 5a and Supplementary Fig. 16 are shown in the Supplementary Information to this Amendment. These changes do not affect the conclusions of the original Article, which has not been corrected online. We apologize for any confusion that these errors may have caused.
