Protein

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

Gene

PDE1B1

Organism
Cricetulus griseus (Chinese hamster) (Cricetulus barabensis griseus)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript 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

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).By similarity

Enzyme regulationi

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