Function

[PDE3B_HUMAN] Cyclic nucleotide phosphodiesterase with a dual-specificity for the second messengers cAMP and cGMP, which are key regulators of many important physiological processes. May play a role in fat metabolism. Regulates cAMP binding of RAPGEF3. Through simultaneous binding to RAPGEF3 and PIK3R6 assembles a signaling complex in which the PI3K gamma complex is activated by RAPGEF3 and which is involved in angiogenesis.^[1] ^[2]

Publication Abstract from PubMed

Phosphodiesterases (PDEs) are enzymes that modulate cyclic nucleotide signaling and as such are clinical targets for a range of disorders including congestive heart failure, erectile dysfunction, and inflammation. The PDE3 family comprises two highly homologous subtypes expressed in different tissues, and inhibitors of this family have been shown to increase lipolysis in adipocytes. A specific PDE3B (the lipocyte-localized subtype) inhibitor would be a very useful tool to evaluate the effects of PDE3 inhibition on lipolysis and metabolic rate and might become a novel tool for treatment of obesity. We report here the three-dimensional structures of the catalytic domain of human PDE3B in complex with a generic PDE inhibitor and a novel PDE3 selective inhibitor. These structures explain the dual cAMP/cGMP binding capabilities of PDE3, provide the molecular basis for inhibitor specificity, and can supply a valid platform for the design of improved compounds.
