CC -!- FUNCTION: Excises uracil residues from the DNA which can arise as a
CC result of misincorporation of dUMP residues by DNA polymerase or
CC deamination of cytosines. Therefore may reduce deleterious uracil
CC incorporation into the viral genome, particularly in terminally
CC differentiated cells which lack DNA repair enzymes. {ECO:0000255|HAMAP-
CC Rule:MF_04046}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolyzes single-stranded DNA or mismatched double-stranded
CC DNA and polynucleotides, releasing free uracil.; EC=3.2.2.27;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_04046};
CC -!- SUBCELLULAR LOCATION: Host nucleus {ECO:0000255|HAMAP-Rule:MF_04046}.
CC -!- SIMILARITY: Belongs to the uracil-DNA glycosylase (UDG) superfamily.
CC UNG family. {ECO:0000255|HAMAP-Rule:MF_04046}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAA24818.1; Type=Erroneous initiation; Evidence={ECO:0000305};
