CC   -!- FUNCTION: May act as transcriptional regulator. Induces apoptosis in
CC       infected cells. Element of infectious replication cycle.
CC   -!- SUBCELLULAR LOCATION: Host nucleus. Note=Host nucleus of infected
CC       cells.
CC   -!- INDUCTION: VP1 and VP2 are detected 12 hours post infection, while VP3
CC       only after 24 hours.
CC   -!- SIMILARITY: Belongs to the gyrovirus apoptin family. {ECO:0000305}.
