OverviewNCBI Gene
The product of this gene belongs to the family of G-protein coupled receptors. This family has several receptor subtypes with different pharmacological selectivity, which overlaps in some cases, for various adenosine and uridine nucleotides. This receptor is involved in platelet aggregation, and is a potential target for the treatment of thromboembolisms and other clotting disorders. Mutations in this gene are implicated in bleeding disorder, platelet type 8 (BDPLT8). Alternative splicing results in multiple transcript variants of this gene. [provided by RefSeq, Jul 2013]

Whether an antibody against P2RY12 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 P2RY12 as an antibody target. Whether an autoantibody or antibody against P2RY12 could matter depends on whether native P2RY12 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
P2RY12 is annotated at the cell surface, where native P2RY12 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 P2RY12 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
