After publication of this manuscript, the authors noticed that the entries concerning the two glutathione peroxidases in Table I were accidentally reversed. GPX7 remains in the ER with a stop codon prior to the localization motif, and GP7R (also known as FLJ23636) changes its localization to the Golgi, as per Fig. 4. A corrected version of the table is provided below. We apologize for this oversight.
