Correction to: Nature Cell Biology https://doi.org/10.1038/ncb2860, published online 27 October 2013.
In the version of this Article originally published, the labels for Rictor and mTOR in the whole cell lysate (WCL) blots were swapped in Fig. 3b and the mTOR blot was placed upside down. Unprocessed blots of mTOR were also missing from Supplementary Fig. 9. The corrected Figs are shown below. In addition, control blots for the mTOR antibody (Cell Signalling Technology #2972) were also missing. These are now provided below, as Fig. 9, and show that the lower band is likely non-specific.
