OverviewNCBI Gene
The protein encoded by this gene is a zinc finger transcription factor and contains an N-terminal POZ domain. This protein acts as a sequence-specific repressor of transcription, and has been shown to modulate the transcription of STAT-dependent IL-4 responses of B cells. This protein can interact with a variety of POZ-containing proteins that function as transcription corepressors. This gene is found to be frequently translocated and hypermutated in diffuse large-cell lymphoma (DLCL), and may be involved in the pathogenesis of DLCL. Alternatively spliced transcript variants encoding different protein isoforms have been found for this gene. [provided by RefSeq, Aug 2015]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads BCL6 as an antibody target. Whether an autoantibody or antibody against BCL6 could matter depends on whether native BCL6 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
BCL6 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 BCL6 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
