Co-opted SUMO machinery promotes condensate formation associated with membranous replication organelles of a positive-strand RNA virus

Proceedings of the National Academy of Sciences, Volume 122, Issue 24, June 2025. <br/>SignificanceViruses with positive-strand RNA genomes cause many diseases in humans and plants. These viruses code for a small number of proteins. Posttranslational modifications expand the repertoire of their functions. In this work, we show that p33 …
