To prevent proteins from being damaged during cellular stress, they are concentrated in so-called stress granules. Scientists from the department of Cellular Biochemistry at the Max Planck Institute of Biochemistry have now been able to show for the first time that the protein Urm1 has a critical role in this process. In yeast cells, the ubiquitin-like protein facilitates the onset of phase separation and thus the formation of stress granules. The results of the study were published in the scientific journal Cell.
