Target Background

E3 ubiquitin-protein ligase. The BRCA1-BARD1 heterodimer specifically mediates the formation of 'Lys-6'-linked polyubiquitin chains and coordinates a diverse range of cellular pathways such as DNA damage repair, ubiquitination and transcriptional regulation to maintain genomic stability. Plays a central role in the control of the cell cycle in response to DNA damage. Acts by mediating ubiquitin E3 ligase activity that is required for its tumor suppressor function. Also forms a heterodimer with CSTF1/CSTF-50 to modulate mRNA processing and RNAP II stability by inhibiting pre-mRNA 3' cleavage.
Gene References into Functions
  1. Study shows that tamoxifen-resistant breast cancer cells are resistant to DNA-damaging chemo- and radiotherapy because of upregulated BARD1 and BRCA1, which is caused by activated PI3K/AKT pathway. PMID: 29686231
  2. The results reveal new information for the manner in which full-length BRCA1 engages its binding partner, BARD1, under oxidative stress conditions. PMID: 28262780
  3. BARD1 RING domain is critical to BRCA1/BARD1 binding to nucleosomes and hence to ubiquitylation of histone H2A and also critical to transcriptional repression of BRCA1-regulated genes active in estrogen metabolism. PMID: 29367421
  4. BARD1delta binds more efficiently than BARD1 to telomere binding proteins and causes their depletion from telomeres, leading to telomere and chromosomal instability and tumor cell cycle arrest. PMID: 28030839
  5. BRCA1-BARD1 mutants with weakened RAD51 interactions show compromised DNA joint formation and impaired mediation of homologous recombination and DNA repair in cells; results identify a late role of BRCA1-BARD1 in homologous recombination, an attribute of the tumour suppressor complex that could be targeted in cancer therapy PMID: 28976962
  6. variants in BARD1 were associated with moderate risks of breast cancer. PMID: 28418444
  7. NPM1 downregulation by P-STAT5 is mediated by impairing the BRCA1-BARD1 ubiquitin ligase, which controls the stability of NPM1. In turn, decreased NPM1 levels led to suppression of p53 expression, resulting in enhanced cell survival. PMID: 28005077
  8. In MCF-7 cells BARD1 variants do vary considerably their cellular distribution and in their ability to influence apoptotic response to cisplatin. PMID: 27477900
  9. substitutions that create a structurally intact BRCA1/BARD1 heterodimer that is inactive in vitro with all E2 enzymes. Other substitutions in BRCA1 or BARD1 RING domains result in hyperactivity, revealing that both proteins have evolved attenuated activity. Loss of attenuation results in decreased product specificity, providing a rationale for why nature has tuned BRCA1 activity. PMID: 27977889

  14. BRCA pathway germline mutation (in BRCA1, BRCA2 or BARD1 genes) was present in 10 of the 42 investigated triple-negative breast cancer patients rendering them susceptible to homologous recombination deficiency. PMID: 26010302
  15. Study presents four different pathogenic BARD1 variants identified in ovarian cancer patients. Three of them result in incorrect splicing of the corresponding exons, which may prompt expression of specific BARD1 isoforms and carcinogenesis. PMID: 26329992

  20. FOXK2 might act as a negative regulator of ERalpha, and its association with both ERalpha and BRCA1/BARD1 could lead to the down-regulation of ERalpha transcriptional activity, effectively regulating the function of ERalpha. PMID: 25740706
  21. Increased expression of the BARD1 protein, with its ubiquitin ligase function, was associated with significantly improved overall and disease-free survival, which has yet to be documented for ACC. PMID: 25657202
