[Human 7,8-dihydro-8-oxoguanine triphosphatase protein (197 aa, 23 kD - unprocessed precursor) is encoded by the nudix (nucleoside diphosphate linked moiety X)-type motif 1 gene (NUDT1). Isoforms of this soluble protein are localized to both the cytoplasm and mitochondria of the cell. It catalyzes the hydrolysis of 8-oxo-dGTP to yield 8-oxo-dGMP and diphosphate. Misincorporation of 8-oxo-dGTP into DNA can result in A:T to C:G transversion mutations. Therefore, this enzyme is considered to be antimutagenic. ( NCI )]
