OverviewNCBI Gene

The protein encoded by this gene belongs to the cyclic nucleotide phosphodiesterase (PDE) family, and PDE4 subfamily. This PDE hydrolyzes the second messenger, cAMP, which is a regulator and mediator of a number of cellular responses to extracellular signals. Thus, by regulating the cellular concentration of cAMP, this protein plays a key role in many important physiological processes. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.[provided by RefSeq, Jul 2011]

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads PDE4C as an antibody target. Whether an autoantibody or antibody against PDE4C could matter depends on whether native PDE4C is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

PDE4C 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 PDE4C as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
