OverviewNCBI Gene

The protein encoded by this gene belongs to the AAA ATPase family. This family member includes an N-terminal bromodomain. It has been found to be localized to the nucleus, partly to replication sites, consistent with a chromatin-related function. Alternative splicing of this gene results in multiple transcript variants.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads ATAD2B as an antibody target. Whether an autoantibody or antibody against ATAD2B could matter depends on whether native ATAD2B is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

ATAD2B 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 ATAD2B as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
