Description

An eleven-author team uncovers a protein that both helps and hinders the erasing of DNA methylation. Methyl tags on DNA steer development, and the TET enzymes remove them. PROSER1, a partner of those enzymes, was recently tied to a severe developmental disorder. The team shows it binds every TET family member and holds them in stable complexes on the genome, where they open developmental genes.

Surprisingly, the same protein also shelves spare TET enzymes away from the genome. That shelving stops runaway demethylation and keeps jumping genetic elements silent. Losing the balance in either direction distorts development. The authors cast PROSER1 as a dial with two hands. One presses the enzymes into service, and the other holds them back. They link that dual control to the malformations seen when the protein fails.
