OverviewNCBI Gene

This gene is expressed predominantly in the thyroid. Based on expression patterns similar to thyroid transcription factors and proteins, this gene may function in the development and function of the thyroid. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads C16orf89 as an antibody target. Whether an autoantibody or antibody against C16orf89 could matter depends on whether native C16orf89 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

C16orf89 is annotated as secreted, so native C16orf89 circulates and is directly accessible to antibodies. Secreted and cell-surface proteins are the autoantibody targets most likely to act like drugs, blocking or depleting the native protein.

Annotation status

The present source text does not explicitly label C16orf89 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
