OverviewNCBI Gene
Sequence analysis of this gene suggests that it is encodes a member of the superfamily of G protein-couple receptors. G protein-coupled receptors typically contain seven hydrophobic transmembrane domains, interact with guanine nucleotide binding regulatory proteins, and detect molecules outside the cell and act to transduce these signals into intracellular responses. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2016]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads ADGRF4 as an antibody target. Whether an autoantibody or antibody against ADGRF4 could matter depends on whether native ADGRF4 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
ADGRF4 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 ADGRF4 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
