In the version of this article initially published, the figure titles for Extended Data Fig. 6 and Extended Data Fig. 7 were incorrect. The correct title for Extended Data Fig. 6 is “SLX4-RTEL1 complex formation is dispensable for their recruitment on nascent DNA,” and the correct title for Extended Data Fig. 7 is “SLX4-RTEL1 interaction is needed for tight colocalization between FANCD2 and RNA Pol II.” The errors have been corrected in the HTML and PDF versions of the article.
