OverviewNCBI Gene

The protein encoded by this gene is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. This gene was identified as an oncogene, which confers transforming potential when transfected into mammalian cells. Targeted disruption of the homolog of this gene in mouse resulted in the phenotype of abnormally long hair, which suggested a function as an inhibitor of hair elongation. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against FGF5 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 FGF5 as an antibody target. Whether an autoantibody or antibody against FGF5 could matter depends on whether native FGF5 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

FGF5 is annotated as secreted, so native FGF5 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 FGF5 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
