Identification
Name:2'-Deoxyinosine triphosphate
Description2'-Deoxyinosine triphosphate (dITP) is a deoxyribonucleotide that may be generated from dATP by slow, non-enzymatic hydrolysis or by reduction of ITP. Normally, the cellular dITP concentration is very low. The inability to demonstrate the synthesis of dITP in cellular preparations has been attributed to the presence in the cytoplasm of an inosine triphosphatase pyrophosphatase (ITPase, EC 3.6.1.19), an enzyme that does not permit accumulation of these nucleotides. dITP can be incorporated into DNA by polymerases. The deoxyribonucleotide dITP behaves as a dGTP analogue and is incorporated opposite cytosine with about 50% efficiency. Both isolated nuclei and purified DNA polymerases rapidly incorporated dITP into DNA. In the presence of ATP, dITP is stabilized in extracts of nuclei. dITP exist in all cells and is potentially mutagenic, and the levels of these nucleotides are controlled by ITPase. The function of this ubiquitous protein family is proposed to be the elimination of minor potentially mutagenic or clastogenic purine nucleoside triphosphates from the cell. (PMID: 11278832)

Specific function:
Hydrolyzes O6 atom-containing purine bases deoxyinosine triphosphate (dITP) and xanthosine triphosphate (XTP) as well as 2'-deoxy-N-6-hydroxylaminopurine triposphate (dHAPTP) to nucleotide monophosphate and pyrophosphate. Probably excludes non- standard purines from DNA precursor pool, preventing thus incorporation into DNA and avoiding chromosomal lesions
