OverviewNCBI Gene
This gene encodes a member of the NADPH oxidase family of enzymes responsible for the catalytic one-electron transfer of oxygen to generate superoxide or hydrogen peroxide. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Nov 2012]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads NOX1 as an antibody target. Whether an autoantibody or antibody against NOX1 could matter depends on whether native NOX1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
NOX1 is annotated at the cell surface, where native NOX1 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 NOX1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
