The two structures reported in the article by Chin et al. [(2013). Acta Cryst. D69, 352-366] have been further refined and corrected.

The original structures reported in the article by Chin et al. (2013[Chin, K.-H., Tu, Z.-L., Su, Y.-C., Yu, Y.-J., Chen, H.-C., Lo, Y.-C., Chen, C.-P., Barber, G. N., Chuah, M. L.-C., Liang, Z.-X. & Chou, S.-H. (2013). Acta Cryst. D69, 352-366.]) were incorrectly modeled in the C-terminal region, and contained some notable geometrical deviations. The structures have now been corrected, refined again and validated with MolProbity (Chen et al., 2010[Chen, V. B., Arendall, W. B., Headd, J. J., Keedy, D. A., Immormino, R. M., Kapral, G. J., Murray, L. W., Richardson, J. S. & Richardson, D. C. (2010). Acta Cryst. D66, 12-21.]). The improved structures have been re-deposited in the PDB with the same PDB codes (mSTING-CTD, 4g3l and mSTING-CTD-c-di-GMP complex, 4g4d ). A corrected Table 1[link] is given below. The conclusions of the paper are not changed by these corrections.

§Rfree is the same as Rcryst but for 5.0% of the total reflections chosen at random and omitted from refinement.
##The percentages of residues located in the most favourable, additionally allowed regions and outliers were calculated using the MolProbity program with the default parameters (Chen et al., 2010[Chen, V.
