OverviewNCBI Gene

This gene encodes a member of the tumor protein D52-like family of proteins. These proteins are characterized by an N-terminal coiled-coil motif that is used to form homo- and heteromeric complexes with other tumor protein D52-like proteins. The encoded protein may play a role in spermatogenesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against TPD52L3 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 TPD52L3 as an antibody target. Whether an autoantibody or antibody against TPD52L3 could matter depends on whether native TPD52L3 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

TPD52L3 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 TPD52L3 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
