Application
Phosphodiesterase I from Crotalus adamanteus venom has been used:
- for cleaving the 3′-5′ internucleotide bonds in the linear chains of the RNA oligomers
- as a model for the hydrolysis of prodrugs in phosphodiesterase assay
- as a component in the nucleotide cleavage buffer
Biochem/physiol Actions
Phosphodiesterase I breaks phosphodiester bonds and catalyzes the hydrolysis of various nucleotide polyphosphates. Phosphodiesterase I is released from eucaryotic plasma membranes by phosphatidylinositol-specific phospholipase C. PhosphodiesteraseI (PDEI) can hydrolyze 3′,5′-cyclic adenosine monophosphate (cAMP) and3′,5′-cyclic guanosine monophosphate (cGMP). It binds to Ca2+/calmodulin(CaM) that lead to the stimulation of its catalytic activity.PDEIacts as a biotherapeutic for the treatment of cancer, heart diseases,pulmonary, metabolic, neurocognitive, renal, endocrine abnormalities, andneurological disorders.
General description
Research area: Cell signaling. PhosphodiesteraseI (PDEI) exists in three isoforms PDE1A, PDE1B, and PDE1C(2) are localized to the central nervous system, cardiovascular, and other organs.

Pulmonary arterial hypertension (PAH) is a life-threatening disease, characterized by vascular smooth muscle cell hyperproliferation. The calcium/calmodulin-dependent phosphodiesterase 1 (PDE1) may play a major role in vascular smooth muscle cell proliferation. We investigated the expression of PDE1 in explanted lungs

The interaction of proteins with DNA results, in some cases, in DNA bending, and this might have functional importance. However, when the protein-induced bending of DNA is small, its measurement presents a problem. It is shown that the fluorescence resonance
