Correction for Lu et al., EST-based genome-wide gene inactivation identifies ARAP3 as a host protein affecting cellular susceptibility to anthrax toxin

microbiology. For the article “EST-based genome-wide gene inactivation identifies ARAP3 as a host protein affecting cellular susceptibility to anthrax toxin,” by Quan Lu, Wensheng Wei, Paul E. Kowalski, Annie C. Y. Chang, and Stanley N. Cohen, which appeared in issue 49, December 7, 2004, of Proc. Natl. Acad. Sci. USA (101, 17246–17251; first published November 29, 2004; 10.1073/pnas.0407794101), the authors note that on page 17247, the last sentence of the second paragraph, left column, the sequence of the Lenti3 primer was incorrectly written as the complement of the primer that actually was used in the study. The correct sequence for the Lenti3 primer is 5′-CATAGCGTAAAAGGAGCAACA. This error does not affect the conclusions of the article.
