OverviewNCBI Gene

The protein encoded by this gene is localized in the endoplasmic reticulum (ER) and golgi, and is also secreted. Reducing expression of this gene increases susceptibility to ER stress-induced death and results in cell proliferation. Activity of this protein is important in promoting the survival of dopaminergic neurons. The presence of polymorphisms in the N-terminal arginine-rich region, including a specific mutation that changes an ATG start codon to AGG, have been reported in a variety of solid tumors; however, these polymorphisms were later shown to exist in normal tissues and are thus no longer thought to be tumor-related.

LocalizationUniProt · AlphaFold · HPA

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

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