OverviewNCBI Gene

This cell-cycle-regulated gene encodes a protein that mediates leucine-rich nuclear export signal (NES)-dependent protein transport. The protein specifically inhibits the nuclear export of Rev and U snRNAs. It is involved in the control of several cellular processes by controlling the localization of cyclin B, MPAK, and MAPKAP kinase 2. This protein also regulates NFAT and AP-1.

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against XPO1 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 XPO1 as an antibody target. Whether an autoantibody or antibody against XPO1 could matter depends on whether native XPO1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

XPO1 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 XPO1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
