NCBI Protein Information
nudix hydrolase 1
NCBI Summary
Encodes a cytosol-localized nudix hydrolase that hydrolyzes 8-oxo-(d)GTP to its monophosphate form. This protective mechanism prevents the misincorporation of these oxidized nucleotides into DNA and RNA. NUDX1 also has a low level of dihydroneopterin triphosphate pyrophosphatase activity in vitro and may participate in the folate synthesis pathway.

UniProt Comments
Mediates the hydrolysis of some nucleoside diphosphate derivatives. Its substrate specificity is unclear. In vitro, it can use NTP, dNTP, 8-oxo-GTP, 8-oxo-dGTP, dGTP, dATP, dTTP or dihydroneopterin triphosphate (DHNTP) as substrate. Has some NADH pyrophosphatase activity in vitro; however, such activity may not be relevant in vivo due to the high concentration of manganese used during the experiments. Plays an important role in protection against oxidative DNA and RNA damage by removing oxidatively damaged form of guanine.
