OverviewNCBI Gene

This gene encodes a member of the ovarian tumor domain (OTU)-containing subfamily of deubiquitinating enzymes. Deubiquitinating enzymes are primarily involved in removing ubiquitin from proteins targeted for degradation. This protein may function as a negative regulator of the cell cycle in B cells.

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against OTUD6B 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 OTUD6B as an antibody target. Whether an autoantibody or antibody against OTUD6B could matter depends on whether native OTUD6B is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

OTUD6B 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 OTUD6B as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
