Applicazioni

Inosine 5′-triphosphate (ITP) is used in studies on the impact of deamination of ATP and GTP by various enzymes and chemical processes. ITP may be used as a substrate to study the specificity and kinetics of nucleoside-5′-triphosphatase and ATPase. ITP is also used to study activation of various ATPases and GTPases.
Inosine 5′-triphosphate trisodium salt has been used to investigate its influence on the chromosome aberration rate, the mitotic rate, sister-chromatid exchange (SCE) frequency, the proportion of first (X1), second (X2) and third (X3) division metaphases of human peripheral lymphocytes.

Azioni biochim/fisiol

Inosine 5′-triphosphate (ITP) has the ability to support the initiation of effector system. It can prevent guanosine 5′-triphosphate (GTP) hydrolysis, that is catalysed by transducin (TD). ITP can proficiently induce secretion in permeabilized cells than GTP. Instead of GTP, ITP can be used for the initiation and the elongation steps of reovirus transcription. ITP can also replace GTP in the activation of G-protein.

The contraction of cardiac muscle that has been treated with glycerol requires Ca2+ (pCa 8-5), when MgATP is used as a substrate. In contrast, this preparation contracts, even in the absence of Ca2+ (pCa 8-10), when ATP is replaced by

The G(s)-proteins G(salpha-short) (G(salphaS)) and G(salpha-long) (G(salphaL)), and the olfactory G(s) protein (G(alphaolf)) mediate activation of adenylyl cyclase by the beta(2)-adrenoceptor (beta(2)AR). Early studies showed that the purine nucleotides GTP, ITP, and XTP differentially support receptor-mediated adenylyl cyclase activation in
