BRISC and BRCA1-A complex member 2 (BRE)

The protein contains 383 amino acids for an estimated molecular weight of 43552 Da.

 

Component of the BRCA1-A complex, a complex that specifically recognizes 'Lys-63'-linked ubiquitinated histones H2A and H2AX at DNA lesions sites, leading to target the BRCA1-BARD1 heterodimer to sites of DNA damage at double-strand breaks (DSBs). The BRCA1-A complex also possesses deubiquitinase activity that specifically removes 'Lys-63'-linked ubiquitin on histones H2A and H2AX (PubMed:17525341, PubMed:19261746, PubMed:19261749, PubMed:19261748). In the BRCA1-A complex, it acts as an adapter that bridges the interaction between BABAM1/NBA1 and the rest of the complex, thereby being required for the complex integrity and modulating the E3 ubiquitin ligase activity of the BRCA1-BARD1 heterodimer (PubMed:21282113, PubMed:19261748). Component of the BRISC complex, a multiprotein complex that specifically cleaves 'Lys-63'-linked ubiquitin in various substrates (PubMed:19214193, PubMed:24075985, PubMed:25283148, PubMed:26195665). Within the BRISC complex, acts as an adapter that bridges the interaction between BABAM1/NBA1 and the rest of the complex, thereby being required for the complex integrity (PubMed:21282113). The BRISC complex is required for normal mitotic spindle assembly and microtubule attachment to kinetochores via its role in deubiquitinating NUMA1 (PubMed:26195665). The BRISC complex plays a role in interferon signaling via its role in the deubiquitination of the interferon receptor IFNAR1; deubiquitination increases IFNAR1 activity by enhancing its stability and (updated: Jan. 31, 2018)

CLONING

Li et al. (1995) cloned BRE from a placenta cDNA library. The deduced protein contains 383 amino acids. Northern blot analysis of normal human fibroblasts detected a single BRE mRNA at 1.7 to 1.9 kb. Northern blot analysis of several rat tissues detected highest expression in testis and intermediate expression in brain and ovary. Using the juxtamembrane domain of the p55 TNF receptor (TNFRSF1A; 191190) as bait in a yeast 2-hybrid screen, Gu et al. (1998) cloned Bre from a mouse cerebellum cDNA library.

GENE FUNCTION

Li et al. (1995) found that the expression of BRE decreased following DNA damage in normal human fibroblasts caused by UV irradiation or 4-nitroquinoline-1-oxide (4NQO) exposure. Similar decreased BRE expression was observed in retinoic acid-treated human brain glioma cells and promyelocytic cells. BRE expression was unchanged in cells following growth inhibition. Using protein-binding assays and immunoprecipitation analysis in HEK293 cells, Gu et al. (1998) confirmed the interaction between mouse Bre and Tnfrsf1a. Bre specifically interacted with Tnfrsf1a but not with other TNF family members. Overexpression of Bre inhibited TNF-induced NF-kappa-B activation. Dong et al. (2003) demonstrated that in human cell lines BRE and BRCC3 (300617) are components of a holoenzyme complex containing BRCA1 (113705), BRCA2 (600185), BARD1 (601593), and RAD51 (179617), which they called the BRCA1- and BRCA2-containing complex (BRCC). The complex showed UBC5 (see UBE2D1; 602961)-dependent ubiquitin E3 ligase activity. Inclusion of BRE and BRCC3 enhanced ubiquitination by the complex, and cancer-associated truncations in BRCA1 reduced the association of BRE and BRCC3 with the complex. RNA interference of BRE and BRCC3 in HeLa cells increased cell sensitivity to ionizing radiation and resulted in a defect in G2/M checkpoint arrest. Dong et al. (2003) concluded that the BRCC is a ubiquitin E3 ligase that enhances cellular survival following DNA damage.

MAPPING
