IMPAD1 catalyzes the hydrolysis of phosphoadenosine phosphate (PAP) to adenosine monophosphate (AMP) . This reaction is essential for maintaining the balance of inositol phosphates within the cell, which are critical for various cellular functions, including signal transduction and membrane biogenesis.
IMPAD1 is studied for its role in neurodevelopmental disorders and neurodegenerative diseases. Its involvement in inositol phosphate metabolism makes it a potential target for therapeutic interventions aimed at modulating cellular signaling pathways.
