Function
[PDE4B_HUMAN] 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.[1] [2]

Publication Abstract from PubMed
A PDE4B over 4D-selective inhibitor programme was initiated to capitalise on the recently discovered predominance of the PDE4B subtype in inflammatory cell regulation. The SAR of a tetrahydrobenzothiophene (THBT) series did not agree with either of two proposed docking modes in the 4B binding site. A subsequent X-ray co-crystal structure determination revealed that the THBT ligand displaces the Gln-443 residue, invariably ligand-anchoring in previous PDE4 co-crystal structures, and even shifts helix-15 by 1-2A. For the first time, several residues of the C-terminus previously proposed to be involved in subtype selectivity are resolved and three of them extend into the ligand binding site potentially allowing for selective drug design.
