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. [provided by RefSeq, Aug 2011]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads VIPR2 as an antibody target. Whether an autoantibody or antibody against VIPR2 could matter depends on whether native VIPR2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
VIPR2 is annotated at the cell surface, where native VIPR2 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 VIPR2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
