OverviewNCBI Gene
This gene encodes a secreted fibroblast growth factor carrier protein. The encoded protein plays a critical role in cell proliferation, differentiation and migration by binding to fibroblast growth factors and potentiating their biological effects on target cells. The encoded protein may also play a role in tumor growth as an angiogenic switch molecule, and expression of this gene has been associated with several types of cancer including pancreatic and colorectal adenocarcinoma. A pseudogene of this gene is also located on the short arm of chromosome 4. [provided by RefSeq, Nov 2011]

Whether an antibody against FGFBP1 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 FGFBP1 as an antibody target. Whether an autoantibody or antibody against FGFBP1 could matter depends on whether native FGFBP1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
FGFBP1 is annotated at the cell surface, where native FGFBP1 is exposed to circulating antibodies and is a prime autoantibody target that could block, deplete, or overstimulate it.
Annotation status
The present source text does not explicitly label FGFBP1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
