BRCA2
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.

Interaction
Monomer and dimer (PubMed:20729858). Interacts with RAD51; regulates RAD51 recruitment and function at sites of DNA repair (PubMed:12442171, PubMed:15800615, PubMed:18317453, PubMed:20729832, PubMed:20729859). Interacts with WDR16, USP11, DMC1, ROCK2 and NPM1 (PubMed:15314155, PubMed:15967112, PubMed:20729832, PubMed:21084279). Interacts with SEM1; the interaction masks a nuclear export signal in BRCA2 (PubMed:10373512, PubMed:16205630, PubMed:21719596, PubMed:24013206). Interacts with both nonubiquitinated and monoubiquitinated FANCD2; this complex also includes XRCC3 and phosphorylated FANCG (PubMed:15115758, PubMed:15199141, PubMed:18212739). Part of a BRCA complex containing BRCA1, BRCA2 and PALB2 (PubMed:19369211). Component of the homologous recombination repair (HR) complex composed of ERCC5/XPG, BRCA2, PALB2, DSS1 and RAD51 (PubMed:26833090). Within the complex, interacts with ERCC5/XPG and PALB2 (PubMed:26833090). Interacts directly with PALB2 which may serve as a scaffold for a HR complex containing PALB2, BRCA2, RAD51C, RAD51 and XRCC3 (PubMed:26833090, PubMed:19369211, PubMed:24141787, PubMed:28319063, PubMed:16793542, PubMed:19609323). Interacts with BRCA1 only in the presence of PALB2 which serves as the bridging protein (PubMed:19369211). Interacts with POLH; the interaction is direct (PubMed:24485656). Interacts with the TREX-2 complex subunits PCID2 and SEM1 (PubMed:24896180, PubMed:21719596). Interacts with HSF2BP and BRME1; the interaction with HSF2BP is direct and allows the formation of a ternary complex (PubMed:31242413). The complex BRME1:HSF2BP:BRCA2 interacts with SPATA22, MEIOB and RAD51 (By similarity).
