PDE4D (Phosphodiesterase 4D) is a member of the phosphodiesterase 4 family that specifically hydrolyzes cyclic AMP (cAMP), serving as a key regulator of cAMP signaling in cells. PDE4D is widely expressed in brain, immune cells, and smooth muscle. In the nervous system, PDE4D plays important roles in synaptic plasticity, learning, memory, and mood regulation. PDE4D inhibitors have been studied for cognitive enhancement and anti-inflammatory therapy. Genetic variants in PDE4D are associated with stroke risk and various psychiatric disorders.
PDE4D encodes phosphodiesterase 4D, a cAMP-specific phosphodiesterase with multiple isoforms. It is widely expressed in brain and peripheral tissues. PDE4D is involved in learning, memory, mood, and inflammatory responses.
High expression in brain (cortex, hippocampus, cerebellum) and immune cells. Important for cAMP signaling in multiple tissues.
