RETRACTION
Volume 81, no. 15, p. 8122–8130, 2007, https://doi.org/10.1128/JVI.00125-07. It has been called to our attention that the actin bands in Fig. 2A in Journal of Biological Chemistry 278:40778–40787, 2003, https://doi.org/10.1074/jbc.M303248200 (article retracted), were reused in Fig. 1B and D and Fig. 2A and B. Figures 2A and B were constructed using their original blots. The different panels showing phosphorylation experiments with SREBP-1 and SREBP-2 suggest that these experiments were conducted independently and each panel was constructed from its independent original blots. However, the Flag-tagged SREBP-2 appears to be the same blot; this could be due to an unintentional error during assembling of the figures. We do not have the original blots to verify the blots, as these experiments were conducted more than 15 years ago. Given these circumstances, we retract this paper.
