Protein

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

Gene

PDE4B

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes. May be involved in mediating central nervous system effects of therapeutic agents ranging from antidepressants to antiasthmatic and anti-inflammatory agents.2 Publications

Catalytic activityi

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

Cofactori

a divalent metal cation2 PublicationsNote: 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.2 Publications

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), High affinity cAMP-specific 3',5'-cyclic phosphodiesterase 7A (PDE7A), cAMP-specific 3',5'-cyclic phosphodiesterase 7B (PDE7B), cAMP-specific 3',5'-cyclic phosphodiesterase 4D (PDE4D), cAMP-specific 3',5'-cyclic phosphodiesterase 4B (PDE4B), High affinity cAMP-specific and IBMX-insensitive 3',5'-cyclic phosphodiesterase 8B (PDE8B), High affinity cAMP-specific and IBMX-insensitive 3',5'-cyclic phosphodiesterase 8A (PDE8A)
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.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
