Correction to: Nature Structural & Molecular Biology https://doi.org/10.1038/s41594-020-00518-w, published online 26 October 2020.

In the version of this article initially published online, the reference “Guardia, C. M. et al. Structure of human ATG9A, the only transmembrane protein of the core autophagy machinery. Cell Rep. 31, 107837 (2020)” was omitted. It should have been cited after “A very recent report...” and after “PDB 6WQZ” in the caption for Extended Data Fig. 7a. The error has been corrected in the print, PDF and HTML versions of the article.
