Correction to: Nature Chemical Biology https://doi.org/10.1038/s41589-021-00930-3, published online 22 December 2021.

In the version of this article initially published, there was a PDB code error in the Data availability section for the S1P-bound S1PR1–Gi complex, due to a format issue with the deposit. The correct Electron Microscopy Data Bank (EMDB) and PDB under accession numbers for the S1P-bound S1PR1–Gi complex are EMD-32461 and 7WF7; the old accessions EMD-31224 and 7EO1 have been withdrawn. The Data availability section and Supplementary Table 1 have been updated with the revised numbers.

The changes have been made to the online version of the article.
