Protein

Calcium/calmodulin-dependent 3',5'-cyclic nucleotide phosphodiesterase 1B

Gene

Pde1b

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Cyclic nucleotide phosphodiesterase with a dual-specificity for the second messengers cAMP and cGMP, which are key regulators of many important physiological processes. Has a preference for cGMP as a substrate (By similarity).By similarity

Catalytic activityi

Nucleoside 3',5'-cyclic phosphate + H2O = nucleoside 5'-phosphate.

Cofactori

a divalent metal cationBy similarityNote: Binds 2 divalent metal cations per subunit. Site 1 may preferentially bind zinc ions, while site 2 has a preference for magnesium and/or manganese ions.By similarity

Enzyme regulationi

Type I PDE are activated by the binding of calmodulin in the presence of Ca2+.
