Common Name | Inosine triphosphate |
---|
Description | Inosine triphosphate (ITP) is an intermediate in the purine metabolism pathway. Relatively high levels of ITP in red cells are found in individuals as result of deficiency of inosine triphosphatase (EC 3.1.3.56, ITPase) ITPase is a cytosolic nucleoside triphosphate pyrophosphohydrolase specific for ITP catalysis to inosine monophosphate (IMP) and deoxy-inosine triphosphate (dITP) to deoxy-inosine monophosphate. ITPase deficiency is not associated with any defined pathology other than the characteristic and abnormal accumulation of ITP in red blood cells. Nevertheless, ITPase deficiency may have pharmacogenomic implications, and the abnormal metabolism of 6-mercaptopurine in ITPase-deficient patients may lead to thiopurine drug toxicity. ITPase's function is not clearly understood but possible roles for ITPase could be to prevent the accumulation of rogue nucleotides which would be otherwise incorporated into DNA and RNA, or compete with nucleotides such as GTP in signalling processes.
