OverviewNCBI Gene
The product of this gene belongs to the family of P2 receptors, which is activated by extracellular nucleotides and subdivided into P2X ligand-gated ion channels and P2Y 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, which is a G-protein coupled receptor, is responsive to UDP, partially responsive to UTP and ADP, and not responsive to ATP. It is proposed that this receptor mediates inflammatory responses. Alternative splicing results in multiple transcript variants that encode different protein isoforms. [provided by RefSeq, Mar 2013]

Whether an antibody against P2RY6 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 P2RY6 as an antibody target. Whether an autoantibody or antibody against P2RY6 could matter depends on whether native P2RY6 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
P2RY6 is annotated at the cell surface, where native P2RY6 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 P2RY6 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
