DNA in the cytosol activates immune responses by binding sensors such as cGAMP synthase (cGAS). A set of studies reveal the structural mechanism of DNA sensing and show that cGAS produces a cyclic 2′-5′-linked dinucleotide, a new cellular second messenger.

In the version of this article initially published, the sentence "Three papers now report that cGAS produces a new type of second messenger molecule1,4,5" did not also attribute the finding to reference 6. The error has been corrected in the HTML and PDF versions of the article.
