| Function: | 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. {ECO:0000269|PubMed:10846163, ECO:0000269|PubMed:15003452}. | |

Site 1 may preferentially bind zinc ions, while site 2 has a preference for magnesium and/or manganese ions. {ECO:0000269|PubMed:10846163, ECO:0000269|PubMed:15003452}; | |
| Activity regulation: | Inhibited by rolipram. | |
| Pathway: | Purine metabolism; 3',5'-cyclic AMP degradation; AMP from 3',5'-cyclic AMP: step 1/1. | |
| Tissue specificity: | Expressed in brain, heart, lung and skeletal muscle. | |
| Miscellaneous: | [Isoform PDE4B5]: Brain-specific isoform. {ECO:0000305}. | |
| Similarity: | Belongs to the cyclic nucleotide phosphodiesterase family. PDE4 subfamily. {ECO:0000305}. | |
| Sequence caution: | Sequence=AAA35643.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305}; | |
