Gene Information

human ... BRCA1(672)

Specificity

The breast cancer susceptibility gene, BRCA1*, is located on chromosome 17 (at q21), and is mutated in the majority of heritable breast cancers. The mutations within the coding region occur throughout the gene with little apparent clustering. The majority of BRCA1 mutations result in shortened BRCA1 gene products, creating a need for an amino-terminal marker. Antibody MAB4132 recognizes both the full-length and mutated (shortened) forms of BRCA1 in breast cancer cell lines. It also recognizes over-expressed protein in transiently transfected Cos cells. A single cross-reacting protein of approximately 27 kDa is also seen upon immunoprecipitation. No other cross-reacting proteins are detected.

BRAC1 is 220kDa.

*BRCA1 is covered under U.S. patents 5,747,282, 5,753,441 and 6,162,897.

Breast cancer susceptibility gene 1 (BRCA1) encodes a tumor suppressor that is frequently mutated in familial breast and ovarian cancer patients. BRCA1 functions in multiple important cellular processes including DNA damage repair, cell cycle checkpoint activation, protein ubiquitination, chromatin remodeling
