OverviewNCBI Gene

The protein encoded by this gene is part of the FTS/Hook/FHIP (FHF) complex, which can interact with members of the homotypic vesicular protein sorting (HOPS) complex. This interaction suggests that the encoded protein is involved in vesicle trafficking. [provided by RefSeq, Dec 2016]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against FHIP1B 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 FHIP1B as an antibody target. Whether an autoantibody or antibody against FHIP1B could matter depends on whether native FHIP1B is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

FHIP1B 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 FHIP1B as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.

Canonical record: https://seroatlas.com/gene/FHIP1B. Study-independent annotations aggregated from UniProt, Human Protein Atlas, PubMed, IEDB, Pfam, InterPro, Gene Ontology, AlphaFold, gnomAD, DepMap, ClinVar, TCGA. Catalog release seroatlas-reviewed-human-uniprot-20260313.

Seroatlas is the reference for exploring autoantibody and antibody serology at the human-protein level: the autoreactome and human serome, multiplex serology (HuProt, HuScan, VirScan, PhIP-Seq).
