BRCA2

BRCA2

symbol for a breast cancer gene with activity similar to that of BRCA1.

BRCA2

A gene on chromosome 13q12.3 that encodes a protein which, like BRCA1, is involved in maintenance of genome stability, especially the homologous recombination pathway for double-stranded DNA repair; like BRCA1, it carries a marked increase in the lifetime risk of breast and ovarian cancer.

BRCA2 protein also controls cell growing, and interacts with RAD51 in DNA repair and homologous recombination (10).
7654dupA is predicted to result in the substitution of isoleucine for asparagine at amino acid position 2552 followed by a premature truncation of the BRCA2 protein at amino acid position 2553.
The BRCA2 protein is involved in repairing damaged DNA, playing a critical role in stabilising cells.
The host laboratory has purified full-length BRCA2 protein and shown that it facilitates RAD51-mediated HR by acting as a molecular chaperone for RAD51 filament formation.
These observations have created a question: Why does the BRC4 peptide inhibit filament formation but the whole BRCA2 protein appears to promote filament formation?
BRCA2 protein acts as a mediator, helping another protein, RAD51, to associate with a single strand of DNA and stimulating its activity.
The BRCA1 and BRCA2 protein products are classified as tumour suppressor genes and are involved in DNA repair, genomic stability, transcriptional regulation and cell cycle control.
The specificity of the antibody was verified against the full-length (390 kDa) BRCA2 protein extracted from HeLa cell nuclear extract.
The research studied how the BRCA2 protein molecule interacts with Rad51 and how the process goes wrong when BRCA2 is faulty.
The functions of the BRCA2 protein appear similar to that of BRCA1, although BRCA2 tumours have different cellular expression.
The mRNA is then translated to the BRCA1 and BRCA2 proteins, which become products of nature found within the cell.
Non-cancerous cells will survive the treatment, because the normal BRCA1 and BRCA2 proteins are key components in DNA repair.
