描述
8-Oxo-dGMP is a metabolite of 8-oxo-dGTP. 8-Oxo-7,8-dihydro-2'-deoxyguanosine 5'-triphosphate (8-oxo-dGTP) is a potent mutagenic substrate for DNA synthesis. 8-Oxo-dGTP is rapidly degraded to 8-oxo-dGMP by cellular 8-oxo-dGTPase activity. 8-Oxo-dGMP is further degraded to 8-oxo-deoxyguanosine by a nucleotidase. 8-Oxo-dGMP is the most preferred substrate of this nucleotidase enzyme (PMID: 7819228). The human MutT homologue (hMTH1), an 8-oxo-dGTPase, prevents misincorporation of 8-oxo-dGTP into DNA by hydrolyzing it to 8-oxo-dGMP. hMTH1 mRNA is overexpressed in human renal cell carcinomas and breast tumors. Likewise, elevated levels of hMTH1 protein have also been detected in brain tumors. (PMID: 12757855) [HMDB]
