CC   -!- FUNCTION: Plays a role in virus cell tropism, and may be required for
CC       efficient virus replication in macrophages. Interferes with host NF-
CC       kappa-B promoter activity mediated by TLR8. Mechanistically, inhibits
CC       the phosphorylation and subsequent nuclear translocation of host NF-
CC       kappa-B RELA subunit downstream of TLR8. Promotes the expression of the
CC       autophagy-related protein host ULK1 to degrade host STING and inhibit
CC       the interferon response. Inhibits also JAK1- and JAK2-mediated
CC       signaling and thus negatively regulates the IFN-gamma signaling.
CC       {ECO:0000250|UniProtKB:Q89925}.
CC   -!- SUBUNIT: Interacts with host STING1. Interacts with host JAK1; this
CC       interaction leads to JAK1 degradation. Interacts with host JAK2; this
CC       interaction leads to JAK2 degradation. Interacts with host RELA; this
CC       interaction inhibits NF-kappa-B promoter activity.
CC       {ECO:0000250|UniProtKB:Q89925}.
CC   -!- SUBCELLULAR LOCATION: Host cytoplasm {ECO:0000250|UniProtKB:Q89925}.
CC   -!- INDUCTION: Expressed in the early phase of the viral replicative cycle.
CC       {ECO:0000250|UniProtKB:Q89925}.
CC   -!- SIMILARITY: Belongs to the asfivirus MGF 505 family. {ECO:0000305}.
