  • ZNF219 inhibits porcine epidemic diarrhea virus (PEDV) by degrading the viral S2 protein.
  • PEDV significantly impacts the global agricultural economy, and current vaccines are insufficient against emerging strains.
  • ZNF219 is upregulated by viral nonstructural protein 12 (nsp12) during PEDV infection.
  • ZNF219 recruits TRAF6 to ubiquitinate the PEDV S2 protein, leading to its degradation via selective autophagy.
  • The ubiquitinated S2 protein is recognized by p62 and degraded in autolysosomes, inhibiting PEDV replication.
  • This study reveals a novel antiviral mechanism involving ZNF219 and suggests a new target for PEDV treatment.
