The CAPAN-1 cell line, which has 6174delT mutation in the single BRCA2 allele, expresses a truncated BRCA2 protein of 230 kDa that contains the Anti-BRCA2 epitope and retains RAD51 binding but has lost p53 binding. Full length BRCA2 protein will co-migrate on SDS-PAGE with the catalytic subunit of DNA PK which can be detected using Anti-DNA PK, Cat. No. PC127. Antibody should be titrated for optimal results in individual systems.

Germline mutations in BRCA2 predispose carriers to the development of breast, ovarian, and a variety of other cancers. The original localization of the BRCA2 gene was aided by its homozygous deletion in a pancreatic carcinoma; indeed, an excess of pancreatic

Recent work has shown that the murine BRCA2 tumor suppressor protein interacts with the murine RAD51 protein. This interaction suggests that BRCA2 participates in DNA repair. Residues 3196-3232 of the murine BRCA2 protein were shown to be involved in this

Germline mutation of the BRCA2 gene carries a high risk of developing breast cancer. To study the function of this gene, we generated a mutation in Brca2 in mice. Unlike other mutations in the Brca2 gene, which are lethal early

Germline mutations in the putative tumor suppressor gene, BRCA1, predispose women to dramatically elevated risks of breast cancer, while germline mutations in the structurally unrelated gene, BRCA2, predispose both men and women to breast cancer. Recent studies have suggested an

Breast carcinoma is the most common malignancy among women in developed countries. Because family history remains the strongest single predictor of breast cancer risk, attention has focused on the role of highly penetrant, dominantly inherited genes in cancer-prone kindreds (1).
