OverviewNCBI Gene

The protein encoded by this gene shows sequence similarity to the human breast carcinoma metastasis suppressor (BRMS1) protein and the mammalian Sds3 (suppressor of defective silencing 3) proteins. This protein is a component of the mSin3a family of histone deacetylase complexes (HDAC). [provided by RefSeq, Jul 2008]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against BRMS1L 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 BRMS1L as an antibody target. Whether an autoantibody or antibody against BRMS1L could matter depends on whether native BRMS1L is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

BRMS1L 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 BRMS1L as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
