How cells keep their nucleus clean: a fundamental discovery

Scientists at the Research Institute of Molecular Pathology (IMP) in Vienna have developed a CRISPR-Cas9 screening assay that allows to systematically pinpoint regulators of any gene of interest, including cancer-related genes. Using this approach, they discovered how cells transport their clean-up machinery, the proteasome, into the nucleus to maintain protein balance and get rid of unwanted nuclear proteins. The results of this study are now reported in the journal Nature.
