Summary: Enables dITP diphosphatase activity. Acts upstream of or within ITP catabolic process and chromosome organization. Predicted to be located in cytosol and nucleoplasm. Predicted to be active in cytoplasm. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and sensory organ. 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, Nov 2024]

Neural stem cell-specific ITPA deficiency causes neural depolarization and epilepsy.
Title: Neural stem cell-specific ITPA deficiency causes neural depolarization and epilepsy.
The authors analysed ITPA-deficient human and mouse cells, and revealed that ITPA deficiency induces MLH1/PMS2- and p53-dependent growth arrest and DNA instability in mammalian cells.
Title: Deoxyinosine triphosphate induces MLH1/PMS2- and p53-dependent cell growth arrest and DNA instability in mammalian cells.
The role of ITPase in mice is to exclude ITP from the ATP pool, and the main target substrate of this enzyme is rITP
Title: ITPase-deficient mice show growth retardation and die before weaning.
In the mouse genome, we found one processed Itpa gene-like sequence and two processed Itpa pseudogenes as well as the Itpa gene itself with introns.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
