ASFV CN/GS/2018 pE248R is conjugated to SUMO1 at lysines 103 and 240 by PIAS4, and this SUMOylation is essential for viral replication and virulence in swine.
- Why it matters: Effective vaccines and antivirals for African swine fever virus remain unavailable, and how ASFV exploits host SUMOylation machinery for pathogenesis has been unclear.
- What they did: They showed PIAS4 interacts with pE248R through SUMO interaction motifs and promotes pE248R SUMOylation at lysines 103 and 240, increasing pE248R stability; pE248R mutations disrupting these regions blocked replication in vitro and attenuated virus in swine.
- The result: Preventing pE248R SUMOylation inhibits ASFV CN/GS/2018 infection, identifying a druggable virus–host interaction node that could guide next-generation attenuated ASFV vaccine development.
