Function DNA repair enzyme involved in the repair of deaminated bases. Selectively cleaves double-stranded DNA at the second phosphodiester bond 3' to a deoxyinosine leaving behind the intact lesion on the nicked DNA.
Catalytic activity Reaction=Endonucleolytic cleavage at apurinic or apyrimidinic sites to products with a 5'-phosphate.; EC=3.1.21.7;
case <FTGroup:1>
Cofactor Mg(2+)
end case
Subcellular location Cytoplasm.
Similarity Belongs to the endonuclease V family.
