2',5'-phosphodiesterase 12 (PDE12)

Enzyme that cleaves 2',5'-phosphodiester bond linking adenosines of the 5'-triphosphorylated oligoadenylates, triphosphorylated oligoadenylates called 2-5A modulates the 2-5A system. This enzyme degraded triphosphorylated 2-5A to generate AMP and ATP.

Also cleaves 3',5'-phosphodiester bond of oligoadenylates. Plays a role as a negative regulator of the The 2-5A system that is among the important pathways for antiviral and antitumor functions induced by interferons (IFNs).
