Summary: Enables nucleoside triphosphate diphosphatase activity. Involved in purine deoxyribonucleoside triphosphate catabolic process and pyrimidine deoxyribonucleoside triphosphate catabolic process. Located in cytoplasm and nucleus. Human ortholog(s) of this gene implicated in several diseases, including anemia (multiple); developmental and epileptic encephalopathy 35; hepatitis C; rheumatoid arthritis; and thrombocytopenia. Orthologous to human ITPA (inosine triphosphatase). [provided by Alliance of Genome Resources, Dec 2024]

Preferred Names: nucleoside triphosphate pyrophosphohydrolase HAM1

NP_012603.1

EC 3.6.1.9

Nucleoside triphosphate pyrophosphohydrolase; active against various substrates including ITP, dITP and XTP; mediates exclusion of non canonical purines, pyrimidines from dNTP pools; functions with YJL055W to mediate resistance to 5-FU; specifically reduces the incorporation of 5-FU into RNA without affecting uptake or incorporation of uracil into RNA; protein abundance increases in response to DNA replication stress; yeast HAM1 can complement knockdown of human homolog ITPA
