Application

P1,P4-Di(adenosine-5′) tetraphosphate ammonium salt has been used as a substrate for nudix hydrolyse. It has also been used as a ATP analog and nudix substrate for cleavage factor II Im25 subunit.

Biochem/physiol Actions

Diadenosine polyphosphate (Ap4A) functions as a second messenger in pancreatic cells. Diadenosine polyphosphate is majorly stored in neuronal cells, thrombocytes and chromaffin. It stimulates phospholipase D, fluctuates intracellular calcium levels, induces nitric oxide release, activates 5′-nucleotidase, and inhibits adenosine kinase activity in vitro. The membrane-bound ectoenzymes in endothelial cells in blood plasma and smooth muscle cell metabolize Ap4A.

1. Adenine dinucleotides (Ap3A, Ap4A, Ap5A, Ap6A) are stored in secretory granules of thrombocytes, chromaffin cells and neuronal cells. After release into the extracellular space, the dinucleotides exhibit divergent biological effects on a variety of target cells and organs. The

A role of diadenosine polyphosphates as second messengers was suggested for insulin-secreting cells. It has not yet been investigated whether specific receptors for these compounds exist and how these extracellular compounds and their degradation products may contribute to insulin release.

Diadenosine polyphosphates (ApnAs) can, through interaction with appropriate purinoceptors, affect a range of cellular activities. Ap4A, the most prominent naturally occurring diadenosine polyphosphate, stimulates alterations in intracellular calcium homeostasis and subsequent activation of glycogen breakdown in isolated liver cells.

P1,P4-Diadenosine 5'-tetraphosphate (Ap4A) acts as an extracellular modulator through its interaction with purinoceptors. Our laboratory has demonstrated the presence of an Ap4A receptor in cardiac tissue [1,2]. Due to the rapid hydrolysis of ATP by cardiac membranes the relationship of

Diadenosine polyphosphates released into the extracellular environment influence a variety of metabolic and other cellular activities in a wide range of target tissues. Here we have studied the impact of these novel nucleotides on gluconeogenesis in isolated rat proximal tubules.
