OverviewNCBI Gene

Predicted to enable misfolded protein binding activity; ribonucleoprotein complex binding activity; and ubiquitin protein ligase activity. Predicted to act upstream of or within several processes, including motor behavior; neuron differentiation; and protein quality control for misfolded or incompletely synthesized proteins. Predicted to be located in cytoplasm. [provided by Alliance of Genome Resources, Apr 2025]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against LONRF2 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 LONRF2 as an antibody target. Whether an autoantibody or antibody against LONRF2 could matter depends on whether native LONRF2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

LONRF2 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 LONRF2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.

Canonical record: https://seroatlas.com/gene/LONRF2. 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).
