CC   -!- FUNCTION: Enhances the ribosomal termination-reinitiation event leading
CC       to the translation of major open reading frames on the polycistronic
CC       viral RNAs. {ECO:0000250|UniProtKB:P03558}.
CC   -!- INTERACTION:
CC       P16666; Q9FR53: TOR; Xeno; NbExp=6; IntAct=EBI-8597718, EBI-1382370;
CC   -!- SUBCELLULAR LOCATION: Host cytoplasm. Note=Found in cytoplasmic
CC       occlusion bodies.
CC   -!- MISCELLANEOUS: The inclusion bodies are the site of viral DNA
CC       synthesis, virion assembly and accumulation in the infected cell.
CC   -!- SIMILARITY: Belongs to the caulimoviridae viroplasmin family.
CC       {ECO:0000305}.
