OverviewNCBI Gene

This gene encodes a member of the latrophilin subfamily of G-protein coupled receptors (GPCR). Latrophilins may function in both cell adhesion and signal transduction. In experiments with non-human species, endogenous proteolytic cleavage within a cysteine-rich GPS (G-protein-coupled-receptor proteolysis site) domain resulted in two subunits (a large extracellular N-terminal cell adhesion subunit and a subunit with substantial similarity to the secretin/calcitonin family of GPCRs) being non-covalently bound at the cell membrane.

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against ADGRL3 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 ADGRL3 as an antibody target. Whether an autoantibody or antibody against ADGRL3 could matter depends on whether native ADGRL3 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

ADGRL3 is annotated at the cell surface, where native ADGRL3 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 ADGRL3 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
