Summaries for PDE8B Gene

Entrez Gene Summary for PDE8B Gene

  • The protein encoded by this gene is a cyclic nucleotide phosphodiesterase (PDE) that catalyzes the hydrolysis of the second messenger cAMP. The encoded protein, which does not hydrolyze cGMP, is resistant to several PDE inhibitors. Defects in this gene are a cause of autosomal dominant striatal degeneration (ADSD). Several transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jul 2010]

GeneCards Summary for PDE8B Gene

PDE8B (Phosphodiesterase 8B) is a Protein Coding gene. Diseases associated with PDE8B include Pigmented Nodular Adrenocortical Disease, Primary, 3 and Striatal Degeneration, Autosomal Dominant. Among its related pathways are Signaling by GPCR and G Protein Signaling Pathways. GO annotations related to this gene include signal transducer activity and 3,5-cyclic-AMP phosphodiesterase activity. An important paralog of this gene is PDE7A.

UniProtKB/Swiss-Prot for PDE8B Gene

  • Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes. May be involved in specific signaling in the thyroid gland.

Tocris Summary for PDE8B 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.

  • Primary pigmented nodular adrenocortical disease 3 (PPNAD3) [MIM:614190]: A rare bilateral adrenal defect causing ACTH-independent Cushing syndrome. Macroscopic appearance of the adrenals is characteristic with small pigmented micronodules observed in the cortex. Adrenal glands show overall normal size and weight, and multiple small yellow-to-dark brown nodules surrounded by a cortex with a uniform appearance. Microscopically, there are moderate diffuse cortical hyperplasia with mostly nonpigmented nodules, multiple capsular deficits and massive circumscribed and infiltrating extra-adrenal cortical excrescences with micronodules. Clinical manifestations of Cushing syndrome include facial and truncal obesity, abdominal striae, muscular weakness, osteoporosis, arterial hypertension, diabetes. {ECO:0000269 PubMed:18431404}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Striatal degeneration autosomal dominant (ADSD) [MIM:609161]: A movement disorder affecting the striatal part of the basal ganglia and characterized by bradykinesia, dysarthria and muscle rigidity. These symptoms resemble idiopathic Parkinson disease, but tremor is not present. {ECO:0000269 PubMed:20085714}. Note=The disease is caused by mutations affecting the gene represented in this entry.
