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]
BRCA1和该基因,BRCA2遗传突变,赋予增加的发展乳腺癌或卵巢癌的终生风险。无论BRCA1和BRCA2参与维护稳定的基因组中,专门为双链DNA修复的同源重组途径。该BRCA2蛋白含有称为BRC图案70 AA主题的多个副本,而这些图案调解绑定到RAD51重组其功能DNA修复。 BRCA2被认为是一种肿瘤抑制基因,与BRCA2基因突变的肿瘤通常表现出野生型等位基因的杂合的损失。 [由RefSeq的,2008年12月提供]
