OverviewNCBI Gene

This gene reduces the metastatic potential, but not the tumorogenicity, of human breast cancer and melanoma cell lines. The protein encoded by this gene localizes primarily to the nucleus and is a component of the mSin3a family of histone deacetylase complexes (HDAC). The protein contains two coiled-coil motifs and several imperfect leucine zipper motifs. Alternative splicing results in two transcript variants encoding different isoforms.

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against BRMS1 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Genetic constraint and essentialitygnomAD · DepMap

Does the body need this protein intact? Low LOEUF or a strong DepMap dependency means loss or blockade of the protein is likely to be felt.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads BRMS1 as an antibody target. Whether an autoantibody or antibody against BRMS1 could matter depends on whether native BRMS1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

BRMS1 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 BRMS1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
