Facts about 7,8-dihydro-8-oxoguanine triphosphatase.
Antimutagenic (PubMed:8226881, PubMed:7713500, PubMed:10608900).
Plays a redundant function in sanitizing oxidized nucleotide pools, such as 8-oxo-dGTP pools (PubMed:28679043).Acts as a sanitizing enzyme for oxidized nucleotide pools, thus suppressing cell dysfunction and death induced by oxidative stress (PubMed:12857738, PubMed:24695224, PubMed:24695225). Hydrolyzes 8- oxo-dGTP, 8-oxo-dATP and 2-OH-dATP, thus preventing misincorporation of oxidized purine nucleoside triphosphates to DNA and preventing A:T to C:G and G:C to T:A transversions (PubMed:8226881, PubMed:10373420, PubMed:10608900, PubMed:11756418, PubMed:12857738, PubMed:16607562, PubMed:24695224, PubMed:24695225, PubMed:26999531, PubMed:28035004).

Widely expressed with highest expression in thymus, testis, embryo and proliferating blood lymphocytes.
[Isoform p18]: Cytoplasm, cytosol. Mitochondrion matrix. Nucleus. Mostly present in cytosol (PubMed:7782328). A minor proportion is mitochondrial (PubMed:7782328). A very small amount of the protein is associated with nuclei (PubMed:7782328). Variant Met-124 has decreased efficiency in translocation to mitochondria (PubMed:16607562).; [Isoform p26]: Mitochondrion matrix.
