The BRCA2 (BReast CAncer gene 2) antibody is a crucial tool in studying the BRCA2 protein, a tumor suppressor encoded by the BRCA2 gene located on chromosome 13. BRCA2 plays a vital role in DNA repair through homologous recombination (HR), maintaining genomic stability. Mutations in BRCA2 are strongly linked to hereditary breast and ovarian cancers, as well as pancreatic and prostate cancers. Individuals with pathogenic BRCA2 variants have a significantly higher lifetime risk of developing these cancers.
BRCA2 antibodies are widely used in research and diagnostics to detect protein expression levels, localization, and functional status in tissues or cell lines. They are essential in techniques like immunohistochemistry (IHC), Western blotting, and immunofluorescence to assess BRCA2 loss or dysfunction, which may indicate impaired DNA repair capacity. Clinically, these antibodies help identify patients with BRCA2-deficient tumors, guiding therapeutic decisions such as PARP (poly-ADP ribose polymerase) inhibitor treatments that exploit synthetic lethality in HR-deficient cells.
However, challenges remain in antibody specificity due to BRCA2's large size (~384 kDa) and complex protein interactions with PALB2. RAD51. and other DNA repair mediators. Validated BRCA2 antibodies are critical for accurate research and companion diagnostics in precision oncology. Ongoing studies focus on optimizing detection methods and exploring BRCA2's role beyond HR, including replication fork stabilization and cell cycle regulation.
