The PanX1 panel in the original version of Fig. 6 A was a partial duplicate of the PanX1 panel in Fig. 1. The authors have indicated that this was due to a clerical error during figure preparation. The original version of Fig. 1 and its legend also did not indicate that intervening lanes of the gel image had been removed for presentation purposes. Corrected versions of Fig. 1 and Fig. 6 A and their respective figure legends are shown below.

The html and pdf versions of this article have been corrected. The errors remain only in the print version.
