In the above article [Aneja R, Vangapandu SN, Lopus M, Chandra R, Dulal P, and Joshi HC (2006) Mol Pharmacol 69:1801-1809], there was an error in Fig. 4 on page 1807. One of the published panels was from an experiment different from that described in the figure legend. The corrected version of Fig. 4 appears online only. The figure legend has not been changed.

The online version has been corrected in departure from the print version.

The authors regret this error and apologize for any confusion or inconvenience it may have caused.
