3',5'-cyclic-AMP phosphodiesterase 4A (PDE4A)

Target
PDE4A
Molecular classification
Enzyme, Phosphodiesterase
01

Overview

3',5'-cyclic-AMP phosphodiesterase 4A (PDE4A) is an enzyme that hydrolyzes the second messenger cyclic adenosine monophosphate (cAMP), a key regulator of numerous physiological processes. By breaking down cAMP, PDE4A plays a central role in modulating cellular responses to extracellular signals and maintaining cellular homeostasis. PDE4A is a therapeutic target, specifically isoforms 1, 2, 6, and 7, with inhibitors being explored or used for conditions like depression and chronic inflammatory diseases due to their ability to modulate immune cell function and neuronal signaling.
