Calmodulin-dependent Cyclic Nucleotide Phosphodiesterase (PDE1)

Target
PDE1
Molecular classification
Enzyme, Phosphodiesterase
01

Overview

Calmodulin-dependent cyclic nucleotide phosphodiesterases (PDE1s) are a family of enzymes that hydrolyze cAMP and cGMP, terminating signaling events. Their activity is regulated by calcium/calmodulin, integrating calcium and cyclic nucleotide pathways. PDE1s participate in diverse physiological processes and are potential drug targets.

Other names
CaM-PDECalmodulin-stimulated phosphodiesterase
02

Mechanism of action

PDE1 inhibitors block the hydrolysis of cAMP and cGMP, increasing their intracellular concentrations and prolonging their signaling effects.
