Gene: ITPA (inosine triphosphatase) Homo sapiens
Symbol: ITPA
Name: inosine triphosphatase
Description: Exhibits identical protein binding activity. Predicted to be involved in nucleoside triphosphate catabolic process. Localizes to the cytosol and nuclear body. Implicated in several diseases, including anemia (multiple); early infantile epileptic encephalopathy 35; hepatitis C; precursor lymphoblastic lymphoma/leukemia; and rheumatoid arthritis.
Type: protein-coding
RefSeq Status: REVIEWED
