Protein

cAMP-specific 3',5'-cyclic phosphodiesterase 4C

Gene

PDE4C

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes.1 Publication

Catalytic activityi

Adenosine 3',5'-cyclic phosphate + H2O = adenosine 5'-phosphate.

Cofactori

a divalent metal cation1 PublicationNote: 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.1 Publication

Enzyme regulationi

Inhibited by rolipram.

Pathwayi: 3',5'-cyclic AMP degradation

This protein is involved in step 1 of the subpathway that synthesizes AMP from 3',5'-cyclic AMP.
Proteins known to be involved in this subpathway in this organism are:
  1. cAMP-specific 3',5'-cyclic phosphodiesterase 4C (PDE4C), cAMP and cAMP-inhibited cGMP 3',5'-cyclic phosphodiesterase 10A (PDE10A), cAMP-specific 3',5'-cyclic phosphodiesterase 4A (PDE4A), cAMP-specific 3',5'-cyclic phosphodiesterase 7B (PDE7B), High affinity cAMP-specific 3',5'-cyclic phosphodiesterase 7A (PDE7A), cAMP-specific 3',5'-cyclic phosphodiesterase 4B (PDE4B), cAMP-specific 3',5'-cyclic phosphodiesterase 4D (PDE4D), High affinity cAMP-specific and IBMX-insensitive 3',5'-cyclic phosphodiesterase 8A (PDE8A), High affinity cAMP-specific and IBMX-insensitive 3',5'-cyclic phosphodiesterase 8B (PDE8B)
This subpathway is part of the pathway 3',5'-cyclic AMP degradation, which is itself part of Purine metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes AMP from 3',5'-cyclic AMP, the pathway 3',5'-cyclic AMP degradation and in Purine metabolism.
