BRCA1 interacting protein C-terminal helicase 1

Bach1, BRIP1, FANCJ
The protein encoded by this gene is a member of the RecQ DEAH helicase family and interacts with the BRCT repeats of breast cancer, type 1 (BRCA1). The bound complex is important in the normal double-strand break repair function of breast cancer, type 1 (BRCA1). This gene may be a target of germline cancer-inducing mutations.

New
Green et al., Worcester, United States. In Mol Cell, 18 Oct 2014
In BRAF-positive human CRC cell lines and tumors, MAFG is bound at the promoters of MLH1 and other CIMP genes, and recruits a corepressor complex that includes its heterodimeric partner BACH1, the chromatin remodeling factor CHD8, and the DNA methyltransferase DNMT3B, resulting in hypermethylation and transcriptional silencing.

New
Knipscheer et al., Utrecht, Netherlands. In Embo J, 05 Oct 2014
In contrast, depletion of the FANCJ/BRIP1 helicase causes persistent replication stalling at G-quadruplex structures, demonstrating a vital role for this helicase in resolving these structures.

New
Impact
Murphy et al., Saint Louis, United States. In Cell, Apr 2014
Here, we report that Spic also regulated the development of F4/80(+)VCAM1(+) bone marrow macrophages (BMM) and that Spic expression in BMM and RPM development was induced by heme, a metabolite of erythrocyte degradation.
Etiology of familial breast cancer with undetected BRCA1 and BRCA2 mutations: clinical implications.
Review
New
Yiannakopoulou, Athens, Greece. In Cell Oncol (dordr), Feb 2014
RESULTS: After excluding BRCA1 and BRCA2 mutations, factors proposed to contribute to familial breast cancer include: chance clustering of apparently sporadic cases, shared lifestyle, monogenic inheritance, i.e., dominant gene mutations associated with a high risk (TP53, PTEN, STK11), dominant gene mutations associated with a relatively low risk (ATM, BRIP1, RLB2), recessive gene mutations associated with horizontal inheritance patterns (sister-sister), and polygenic inheritance where susceptibility to familial breast cancer is thought to be conferred by a large number of low risk alleles.

Breast cancer genes: beyond BRCA1 and BRCA2.
Review
Vega et al., Spain. In Front Biosci, 2012
Moreover, a combination of family-based and population-based approaches indicated that genes involved in DNA repair, such as CHEK2, ATM, BRIP1 (FANCJ), PALB2 (FANCN) and RAD51C (FANCO), are associated with moderate BC risk.
Hereditary breast cancer: the era of new susceptibility genes.
Review
Fostira et al., Athens, Greece. In Biomed Res Int, 2012
5%-10% of breast cancer cases are hereditary and are caused by pathogenic mutations in the considered reference BRCA1 and BRCA2 genes.

Wang, Baltimore, United States. In Nat Rev Genet, 2007
Fanconi anaemia (FA) has recently become an attractive model to study breast cancer susceptibility (BRCA) genes, as three FA genes, FANCD1, FANCN and FANCJ, are identical to the BRCA genes BRCA2, PALB2 and BRIP1.
