OverviewNCBI Gene

The protein encoded by this intronless gene is a member of the JUN family, and a functional component of the AP1 transcription factor complex. This protein has been proposed to protect cells from p53-dependent senescence and apoptosis. Alternative translation initiation site usage results in the production of different isoforms (PMID:12105216). [provided by RefSeq, Nov 2013]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against JUND can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Genetic constraint and essentialitygnomAD · DepMap

Does the body need this protein intact? Low LOEUF or a strong DepMap dependency means loss or blockade of the protein is likely to be felt.

Antibody and autoantibody relevanceSeroatlas analysis

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

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