text	localizes to synaptosomal membranes
	with GUCA1A are coexpressed in the same population of the olfactory sensory neurons
	presence of GUCY2D, GUCA1A, and PDE2A predominant in the cilia, yet to a lesser degree, they are also present in other regions of the olfactory neurons

basic FUNCTION	having 3',5'-cyclic nucleotide phosphodiesterase activity
	hydrolyzing both cyclic AMP (cAMP) and cyclic GMP (cGMP)
	potentially TNF-alpha-mediated up-regulation of PDE2A may destabilize endothelial barrier function in sepsis
	regulates the basal cGMP concentration in thalamic neurons
	promotes activation of NADPH oxidase-dependent ROS production and subsequent endothelial proliferation and angiogenesis
	plays a fundamental role in signal transduction
	plays a major role in regulating dopamine-stimulated cAMP production in striatal neurons
	preferential distribution of PDE2A into axons and terminals of the principal neurons suggests roles in regulation of axonal excitability or transmitter release
	PDE2A serves likely as the downstream transducer of cGMP signals produced by NPR1 activation
	PDE2A performs likely the important function of regulating neurotransmitter release by negatively linking cGMP signals to the cAMP pathway
	appears to play an important role in growth and invasion of the human malignant melanoma PMP cell line
	exerts its action on cognitive processes via the control of intracellular second messengers, cGMP and, to a lesser extent, cAMP

INTERACTION

small molecule

protein	PDE2A plays an essential role in the NPPA effect on synaptic transmission
	interaction with over-expressed AIP does not seem to affect PDE2A function, but the reported effect on PDE4A is, in contrast, reduced enzymatic activity

REGULATION

Other

inhibition of PDE2A, by enhancing the hormone-dependent cAMP response locally, affects mitochondria dynamics and protects from apoptotic cell death
