Protein attributes

Sequence length	278 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Involved in nucleotide metabolism: produces dUMP, the immediate precursor of thymidine nucleotides and decreases the intracellular concentration of dUTP to avoid uracil incorporation into DNA. Induces immune dysregulation that contributes to the pathophysiology of the virus infection By similarity.
Catalytic activity	dUTP + H2O = dUMP + diphosphate.
Cofactor	Magnesium By similarity.
Subunit structure	Monomer By similarity.
Sequence similarities	Belongs to the dUTPase family.
