Plays a role in signal transduction by regulating the intracellular concentration of cyclic nucleotides. This phosphodiesterase catalyzes the specific hydrolysis of cGMP to 5'-GMP (PubMed:9714779, PubMed:15489334). Specifically regulates nitric-oxide-generated cGMP (PubMed:15489334).2 Publications

Caution

Was initially thought to act as a major regulator of cardiac hypertrophy in myocytes and muscle and investigations have been made on selective PDE5A inhibitors that could protect against cardiovascular disease. However, while PDE5A regulates nitric-oxide-generated cGMP, nitric oxide signaling is often depressed by heart disease, limiting its effect. Moreover, clinical trial using PDE5A inhibitors were disappointing.1 Publication

<p>This subsection of the 'Function' section provides information relevant to cofactors. A cofactor is any non-protein substance required for a protein to be catalytically active. Some cofactors are inorganic, such as the metal atoms zinc, iron, and copper in various oxidation states. Others, such as most vitamins, are organic.<p><a href='/help/cofactor' target='_top'>More...</a></p>Cofactori

This protein is involved in step 1 of the subpathway that synthesizes GMP from 3',5'-cyclic GMP.
Proteins known to be involved in this subpathway in this organism are:
  1. cGMP-specific 3',5'-cyclic phosphodiesterase (PDE5A), cAMP and cAMP-inhibited cGMP 3',5'-cyclic phosphodiesterase 10A (PDE10A), High affinity cGMP-specific 3',5'-cyclic phosphodiesterase 9A (PDE9A)
This subpathway is part of the pathway 3',5'-cyclic GMP degradation, which is itself part of Purine metabolism.

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:i9E30C6C182F13388
