HSF2BP Interacts with a Conserved Domain of BRCA2 and Is Required for Mouse Spermatogenesis

Cell Reports, 2019
Summary: The tumor suppressor BRCA2 is essential for homologous recombination (HR), replication fork stability, and DNA interstrand crosslink repair in vertebrates.

A complex of BRCA2 and PP2A-B56 is required for DNA repair by homologous recombination

Nature Communications, 2021
BRCA2 plays a central role in facilitating DNA repair by homologous recombination (HR). Here the authors describe how BRCA2 forms a complex with the protein phosphatase PP2A-B56 in response to DNA damage, which is required for HR.

BRCA2 protein expression in sporadic breast carcinoma with or without allelic loss ofBRCA2 [PDF]

International Journal of Cancer, 2000
To elucidate the cellular role of BRCA2 in sporadic breast tumors, we studied the cellular localization and the expression of BRCA2 in carcinomas presenting or not allelic loss of BRCA2. The breast tumors were first classified with or without allelic loss of BRCA2 and then immunohistochemical staining was performed on tumors and matched normal tissues ...

Inherited mutations impair responses to environmental carcinogens: Cancer prevention in mutation carriers [PDF]

, 2011
Some environmental carcinogens may be responsible for a modest increase in the numbers of cancers after years of exposure. Economic or political factors weigh against widespread bans of carcinogens.

Plasticity of BRCA2 function in homologous recombination: genetic interactions of the PALB2 and DNA binding domains.

PLoS Genetics, 2011
The breast cancer suppressor BRCA2 is essential for the maintenance of genomic integrity in mammalian cells through its role in DNA repair by homologous recombination (HR).

Influence of the MDM2 single nucleotide polymorphism SNP309 on tumour development in BRCA1 mutation carriers [PDF]

, 2006
BackgroundThe MDM2 gene encodes a negative regulator of the p53 tumour suppressor protein. A single nucleotide polymorphism (SNP) in the MDM2 promoter (a T to G exchange at nucleotide 309) has been reported to produce accelerated tumour formation in ...

Mutations in BRCA2 and taxane resistance in prostate cancer

Scientific Reports, 2017
Mutations in BRCA1 or BRCA2 define a subset of prostate cancer patients. Herein, we address the question whether BRCA1/2 mutations have a predictive impact on chemotherapy with docetaxel, a widely used drug in patients with metastatic castration ...

Cell cycle-dependent regulation of the bi-directional overlapping promoter of human BRCA2/ZAR2 genes in breast cancer cells

Molecular Cancer, 2010
Background BRCA2 gene expression is tightly regulated during the cell cycle in human breast cells. The expression of BRCA2 gene is silenced at the G0/G1 phase of cell growth and is de-silenced at the S/G2 phase.

Oestrogen‐mediated phosphorylation and stabilization of BRCA2 protein in breast [PDF]

The Journal of Pathology, 2008
AbstractDisease‐associated BRCA2 mutations typically result in protein truncations that delete the phosphorylation‐regulated S3291 BRCA2 domain that interacts with Rad51. BRCA2 hereditary breast cancers are usually ER+, differing from BRCA1 hereditary cancers, which are usually ER−.
