OverviewNCBI Gene
This gene encodes a stimulatory G protein alpha subunit which mediates odorant signaling in the olfactory epithelium. This protein couples dopamine type 1 receptors and adenosine A2A receptors and is widely expressed in the central nervous system. Mutations in this gene have been associated with dystonia 25 and this gene is located in a susceptibility region for bipolar disorder and schizophrenia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2013]

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