Correction to: Nature Structural & Molecular Biology https://doi.org/10.1038/s41594-021-00712-4, published online 31 January 2022.

In the version of this article initially published, there was a typographical error in the abstract. The cofactor LIN-65 originally read “LIN-61.” The corrected sentence now reads “Our study suggests that the noncatalytic, focus-forming function of this SETDB1-like protein and its intrinsically disordered cofactor LIN-65 is physiologically relevant.” The change has been made to the HTML and PDF versions the article.
