Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads OR9K2 as an antibody target. Whether an autoantibody or antibody against OR9K2 could matter depends on whether native OR9K2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

OR9K2 is annotated at the cell surface, where native OR9K2 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 OR9K2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
