Function

UNG_HHV11 Excises uracil residues from the DNA which can arise as a result of misincorporation of dUMP residues by DNA polymerase or deamination of cytosine. Therefore may reduce deleterious uracil incorporation into the viral genome, particularly, in terminally differentiated neurons which lack DNA repair enzymes.^{[1] [2]}
