OverviewNCBI Gene

This gene encodes a member of the G protein-coupled receptor family described as an epididymis-specific transmembrane protein. The encoded protein may be proteolytically processed as it contains a motif shown to be a protein scission motif in some members of this family (PMID: 11973329). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against ADGRG2 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 ADGRG2 as an antibody target. Whether an autoantibody or antibody against ADGRG2 could matter depends on whether native ADGRG2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

ADGRG2 is annotated at the cell surface, where native ADGRG2 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 ADGRG2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
