OverviewNCBI Gene

The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor is highly expressed during embryonic development. It has been shown to interact with TRAF family members, and to activate JNK signaling pathway when overexpressed in cells. This receptor is capable of inducing apoptosis by a caspase-independent mechanism, and it is thought to play an essential role in embryonic development. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Jul 2008]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against TNFRSF19 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads TNFRSF19 as an antibody target. Whether an autoantibody or antibody against TNFRSF19 could matter depends on whether native TNFRSF19 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

TNFRSF19 is annotated at the cell surface, where native TNFRSF19 is exposed to circulating antibodies and is a prime autoantibody target that could block, deplete, or overstimulate it.

Annotation status

The present source text does not explicitly label TNFRSF19 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
