Here, Mac Kain and Maarifi et al. perform a functional CRISPR/Cas9 screen to identify SARS-CoV-2 restriction factors in A549 cells. They identify DAXX, a scaffold protein of nuclear bodies with diverse functions, that has anti-viral activity post SARS-CoV-2 entry, while SARS-CoV-2 has evolved a mechanism to counteract its action via PLpro-mediated proteasomal degradation.
