Breast Cancer Susceptibility Protein 2 (BRCA2) ELISA Kit for Sheep

Inherited mutations in BRCA1 and this gene, BRCA2, confer increased lifetime risk of developing breast or ovarian cancer. Both BRCA1 and BRCA2 are involved in maintenance of genome stability, specifically the homologous recombination pathway for double-strand DNA repair. The BRCA2 protein contains several copies of a 70 aa motif called the BRC motif, and these motifs mediate binding to the RAD51 recombinase which functions in DNA repair. BRCA2 is considered a tumor suppressor gene, as tumors with BRCA2 mutations generally exhibit loss of heterozygosity (LOH) of the wild-type allele. [provided by RefSeq, Dec 2008]

BRCA2: involved in double-strand break repair and/or homologous recombination. May participate in S phase checkpoint activation. Interacts with RAD51 and DSS1. Interacts with ubiquitinated FANCD2. Interacts with PALB2, enables the recombinational repair and checkpoint functions. Interacts with WDR16. Defects in BRCA2 are a cause of genetic susceptibility to breast cancer and may underlie susceptibility to uveal melanoma.
