CC   -!- FUNCTION: Plays a key role in virus oncogenecity in animals. Binds and
CC       sequesters human MUPP1/MPDZ protein in the cytoplasm, preventing it
CC       from playing a role in cellular proliferation regulation. Induces cell
CC       transformation, probably by inactivating MPDZ protein.
CC       {ECO:0000269|PubMed:8189528}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=dUTP + H2O = diphosphate + dUMP + H(+); Xref=Rhea:RHEA:10248,

CC   -!- SIMILARITY: Belongs to the dUTPase family. {ECO:0000305}.
