BRCA1 is a nuclear phosphoprotein that functions as a tumor suppressor. BRCA1 combines with other tumor suppressors, DNA damage sensors, and signal transducers to form a large multi-subunit protein complex known as the BRCA1-associated genome surveillance complex (BASC). BRCA1 associates with RNA polymerase II, and through the C-terminal domain, also interacts with histone deacetylase complexes. This protein thus plays a role in transcription, DNA repair of double-stranded breaks, and recombination. Mutations in this gene are responsible for approximately 40% of inherited breast cancers and more than 80% of inherited breast and ovarian cancers.

BRCA1 is expressed in breast tissue and has been shown to be overexpressed in cancer.
BRCA1 was one of numerous potential early detection biomarkers specific to triple-negative breast cancer in multiple pathways identified.
- Discovery and preliminary confirmation of novel early detection biomarkers for triple-negative breast cancer using preclinical plasma samples from the Women's Health Initiative observational study.
- Plasma biomarker profiles differ depending on breast cancer subtype but RANTES is consistently increased.
