AI Summary

Researchers discovered that an enzyme traditionally known for tagging RNA is directly integrated into the cell‑division machinery, explaining how gene‑reading activity is largely shut down before a cell divides. The study, led by Alarcón and Yale associate professor Lilian Kabeche, identifies this enzyme as a missing component of the shutdown mechanism. Published in Molecular Cell, the work suggests the enzyme could become a target for developing new cancer treatments.
