OverviewNCBI Gene
This gene was first identified as one of the many genes induced by interferon. The encoded protein may play a critical role in the regulation of apoptosis. A minisatellite that consists of 26 repeats of a 12 nucleotide repeating element resembling the mammalian splice donor consensus sequence begins near the end of the second exon. Alternatively spliced transcript variants that encode different isoforms by using the two downstream repeat units as splice donor sites have been described. [provided by RefSeq, Jul 2008]

Whether an antibody against IFI6 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads IFI6 as an antibody target. Whether an autoantibody or antibody against IFI6 could matter depends on whether native IFI6 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
IFI6 is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.
Annotation status
The present source text does not explicitly label IFI6 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
