Adenosine 5′-tetraphosphate, Ap4 or ATPP is a nucleotide. It is produced from ATP and triphosphate (P₃) through the action of acetyl—CoA synthetase.^[1] Acetyl—CoA synthetase also produces adenosine 5'-pentaphosphate through the reaction of ADP and tetraphosphate (P₄).

Functions

ATPP has been found to play physiological roles in some mammals.

Rabbits

ATPP is a constituent of aqueous humor in rabbits, where it was found to reduce the intraocular pressure.^[2]

Rats

ATPP has been suggested to play a regulatory role in rat aorta.
