OverviewNCBI Gene
This locus encodes a subunit of ATP-dependent chromatin-remodeling complexes. The encoded protein has been identified as in integral component of complexes necessary for ligand-dependent transcriptional activation by nuclear hormone receptors. Mutations at this locus have been associated with primary clear cell renal cell carcinoma. [provided by RefSeq, Feb 2012]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads PBRM1 as an antibody target. Whether an autoantibody or antibody against PBRM1 could matter depends on whether native PBRM1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
PBRM1 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 PBRM1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
