RT   nonessential for growth in vitro and viral virulence.";
RL   Virology 230:252-264(1997).
CC   -!- FUNCTION: Prevent apoptosis of host cell by inhibiting caspase-3/CASP3
CC       activation to promote the viral replication. Induces also the
CC       activation of host NF-kappaB. {ECO:0000250|UniProtKB:P69180}.
CC   -!- SUBUNIT: Interacts with subunit p17 of host CASP3.
CC       {ECO:0000250|UniProtKB:P69180}.
CC   -!- SUBCELLULAR LOCATION: Host cytoplasm {ECO:0000250|UniProtKB:P69180}.
CC       Virion {ECO:0000250|UniProtKB:P69180}. Note=Probably accumulates in the
CC       perinuclear cytoplasmic viral factories. Found in association with
CC       viral nucleoid. {ECO:0000250|UniProtKB:P69180}.
CC   -!- INDUCTION: Expressed in the late phase of the viral replicative cycle.
CC       {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the asfivirus IAP family. {ECO:0000305}.
