Protein Name: Inosine triphosphate pyrophosphatase
|
UniprotKB/SwissProt ID: ITPA_HUMAN (Q9BY32)
Gene Name: ITPA
Synonyms: C20orf37
Organism: Homo sapiens (Human).
Function: Pyrophosphatase that hydrolyzes the non-canonical purine nucleotides inosine triphosphate (ITP), deoxyinosine triphosphate (dITP) as well as 2'-deoxy-N-6-hydroxylaminopurine triposphate (dHAPTP) and xanthosine 5'-triphosphate (XTP) to their respective monophosphate derivatives. The enzyme does not distinguish between the deoxy- and ribose forms. Probably excludes non-canonical purines from RNA and DNA precursor pools, thus preventing their incorporation into RNA and DNA and avoiding chromosomal lesions.
