Rabbit Anti-PDE5A
NCBI and Uniprot Product Information
NCBI Description
This gene encodes a cGMP-binding, cGMP-specific phosphodiesterase, a member of the cyclic nucleotide phosphodiesterase family. This phosphodiesterase specifically hydrolyzes cGMP to 5'-GMP. It is involved in the regulation of intracellular concentrations of cyclic nucleotides and is important for smooth muscle relaxation in the cardiovascular system. Alternative splicing of this gene results in three transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]
Uniprot Description
PDE5A: a cGMP-binding, cGMP-specific phosphodiesterase, a member of the cyclic nucleotide phosphodiesterase family. This phosphodiesterase specifically hydrolyzes cGMP to 5'-GMP. It is involved in the regulation of intracellular concentrations of cyclic nucleotides and is important for smooth muscle relaxation in the cardiovascular system. Phosphorylation is regulated by binding of cGMP to the two allosteric sites. Sildenafil (Viagra) is a highly selective and potent inhibitor of PDE5A. Alternative splicing results in four transcript variants encoding distinct isoforms.
