OverviewNCBI Gene
This gene encodes an intermediary protein necessary in the virus-triggered beta interferon signaling pathways. It is required for activation of transcription factors which regulate expression of beta interferon and contributes to antiviral innate immunity. [provided by RefSeq, Jul 2020]

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

Protein binding partners of MAVS in the human serome: UniProt-annotated complex subunits plus reported interactors. Each links to its own Seroatlas record.
Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads MAVS as an antibody target. Whether an autoantibody or antibody against MAVS could matter depends on whether native MAVS is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
MAVS 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 MAVS as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
