OverviewNCBI Gene
This gene encodes a receptor for vasoactive intestinal peptide, a small neuropeptide. Vasoactive intestinal peptide is involved in smooth muscle relaxation, exocrine and endocrine secretion, and water and ion flux in lung and intestinal epithelia. Its actions are effected through integral membrane receptors associated with a guanine nucleotide binding protein which activates adenylate cyclase. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

Whether an antibody against VIPR1 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 VIPR1 as an antibody target. Whether an autoantibody or antibody against VIPR1 could matter depends on whether native VIPR1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
VIPR1 is annotated at the cell surface, where native VIPR1 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 VIPR1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
