Scientists from Delft, Vienna, and Lausanne discovered that the protein machines that shape our DNA can switch direction. Until now, researchers believed that these so-called SMC motors that make loops into DNA could move in one direction only. The discovery, which is published in Cell, is key to understanding how these motors shape our genome and regulate our genes.

Structural maintenance of chromosomes (SMC) proteins are essential for successful chromosome transmission during replication and segregation of the genome in all organisms. SMC proteins were thought to only move in one direction. Now, a new study by scientists from Delft, Vienna, and Lausanne reveals that the protein machines that shape our DNA can switch directions. The new finding is published in Cell in an article titled, “SMC motor proteins …
