RETRACTION
Volume 25, no. 3, p. 1013–1024, 2005, https://doi.org/10.1128/MCB.25.3.1013-1024.2005. We hereby retract this article. We were recently made aware of the presence of irregularities associated with the Western blots shown in several figures. We have further investigated the matter and found that Fig. 2B, 2C, and 3C had been inappropriately assembled. We sincerely apologize to the scientific community for any inconvenience resulting from the publication and subsequent retraction of this article.
