Related Product Information for PDE5A active protein

The cyclic monophosphate nucleotides (cyclic adenosine monophosphate [cAMP] and cyclic guanosine monophosphate [cGMP]) are found ubiquitously in mammalian cells and act as second messenger transducers to effect the intracellular actions of a variety of G protein coupled receptors (GPCRs) for hormones, cytokines, and neurotransmitters. Cyclic nucleotides are important intracellular second messengers which play important role in a variety of signal transduction process. The cyclic nucleotides are hydrolyzed and compartmentalized by a family of enzymes called phosphodieterases. One of the many phosphodiesterases that compartmentalized and hydrolyze cGMP in various tissues is phosphodiesterase type 5A (PDE5A). The cGMP is involved in nitric oxide signaling as well as cell signaling associated with natriuretic peptides and gulanylins. Some of the intracellular biding cites for the cGMP include cyclic nucleotide gated ion channels, cGMP dependent protein kinases, and cyclic GMP biding phosphodiesterases (cGB PDEs). The cGB PDEs include PDE2, PDE3, PDE5, PDE5 and PDE10; the members of these families contain various structural and functional motifs that are conserved. Most of these proteins contain dimeric subunits that contain a highly conserved cGMP binding site and a phosphodiesterase catalytic site.

The cGMP specific phosphodiesterase type 5A (PDE5A) family is comprised of 2 genes (PDE5A and PDE5B) each with multiple splice variants generated by RNA splicing and use of alternate initiation sites. The PDE5 is highly expressed in aorta and lungs, intestine, kidney adrenal gland cerebellum and cerebrum. In cerebellum the PDE5 is highly expressed during neonatal development in Purkinge cells layer. The PDE5 is also abundant in vascular smooth muscle regulating cGMP levels and vascular smooth muscle tonicity. In corpus cavernosum inhibition of PDE5 by sildenafil corrects erectile dysfunctions. The nitric oxide donor sodium notropurside (SNP) stimulate PDE5 activity by cGMP dependent kinase phosphorylation. PDE5A1 has 875 amino acids (99.5 kDa). The amino terminal 142aa of the PDE5 gene showed no sequence homology with other PDEs and also contained serine 92 that is phosphorylated by cGMP kinases. There is growing evidence that supports important roles for PDE5A in both the vasculature and heart.

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.
