Opis

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.[1]

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.[1]
