OverviewNCBI Gene

Ribosomal 40S and 60S subunits associate in the nucleolus and are exported to the cytoplasm. The protein encoded by this gene is involved in the passage of the 60S subunit through the nuclear pore complex and into the cytoplasm. Several transcript variants exist for this gene, but the full-length natures of only two have been described to date. [provided by RefSeq, Feb 2016]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against NMD3 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 NMD3 as an antibody target. Whether an autoantibody or antibody against NMD3 could matter depends on whether native NMD3 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

NMD3 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 NMD3 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
