OverviewNCBI Gene
This gene is specifically expressed in a subpopulation of neuroendocrine cells, and is upregulated by nerve growth factor. The structural organization of this gene is similar to that of the rat gene, and both the translated and the untranslated regions show a high degree of sequence similarity to the rat gene. The encoded secretory protein also shares similarities with the secretogranin/chromogranin family, however, its exact function is not known. [provided by RefSeq, Jul 2008]

Whether an antibody against VGF 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 VGF as an antibody target. Whether an autoantibody or antibody against VGF could matter depends on whether native VGF is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
VGF is annotated as secreted, so native VGF 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 VGF as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
