Summaries for PDE1B Gene

Entrez Gene Summary for PDE1B Gene

  • The protein encoded by this gene belongs to the cyclic nucleotide phosphodiesterase (PDE) family, and PDE1 subfamily. Members of the PDE1 family are calmodulin-dependent PDEs that are stimulated by a calcium-calmodulin complex. This PDE has dual-specificity for the second messengers, cAMP and cGMP, with a preference for cGMP as a substrate. cAMP and cGMP function as key regulators of many important physiological processes. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.[provided by RefSeq, Jul 2011]

GeneCards Summary for PDE1B Gene

PDE1B (Phosphodiesterase 1B) is a Protein Coding gene. Among its related pathways are DAG and IP3 signaling and Activation of cAMP-Dependent PKA. GO annotations related to this gene include calmodulin binding and 3,5-cyclic-AMP phosphodiesterase activity. An important paralog of this gene is PDE7A.

UniProtKB/Swiss-Prot for PDE1B Gene

  • Cyclic nucleotide phosphodiesterase with a dual-specificity for the second messengers cAMP and cGMP, which are key regulators of many important physiological processes. Has a preference for cGMP as a substrate.

Tocris Summary for PDE1B Gene

  • Phosphodiesterases (PDEs) are a family of phosphohydrolyases that catalyze the hydrolysis of 3' cyclic phosphate bonds in adenosine and/or guanine 3',5' cyclic monophosphate (cAMP and/or cGMP). PDEs regulate the second messengers by controlling their degradation.
