What is it about?

The ubiquitin-proteasome system (UPS) has been reported to play important roles in virus-host interplay. We demonstrated that NbSAMDC3 interacts with and promotes the non-lysine ubiquitylation and 26S proteasome-mediated degradation of the Barley stripe mosaic virus γb protein to safeguard against viral infection. Our study expands the current knowledge about how a plant host deploys the UPS to mount defences against viral infections.
