OverviewNCBI Gene

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]

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads PDE5A as an antibody target. Whether an autoantibody or antibody against PDE5A could matter depends on whether native PDE5A is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

PDE5A is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.

Annotation status

The present source text does not explicitly label PDE5A as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
