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.
