A New Method to Correct Misplaced Proteins in Cells

Cells are highly controlled spaces that rely on every protein being in the right place. Many diseases, including cancers and neurodegenerative disorders, are associated with misplaced proteins. In some cancers, for instance, a protein that normally stands watch over DNA replicating in the nucleus is sent far from the DNA it is meant to monitor, allowing cancers to grow.
