OverviewNCBI Gene

Enables identical protein binding activity. Involved in several processes, including macrophage activation involved in immune response; negative regulation of non-canonical NF-kappaB signal transduction; and positive regulation of defense response. Located in several cellular components, including cytosol; extracellular space; and nuclear lumen. [provided by Alliance of Genome Resources, Jul 2025]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against IFI35 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Genetic constraint and essentialitygnomAD · DepMap

Does the body need this protein intact? Low LOEUF or a strong DepMap dependency means loss or blockade of the protein is likely to be felt.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads IFI35 as an antibody target. Whether an autoantibody or antibody against IFI35 could matter depends on whether native IFI35 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

IFI35 is annotated as secreted, so native IFI35 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 IFI35 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
