Regulation of BRCA1 by protein degradation [PDF]
BRCA1, a tumor suppressor protein implicated in hereditary forms of breast and ovarian cancer, is transcriptionally regulated in a proliferation-dependent manner. In this study, we demonstrate a substantial role for proteolysis in regulating the BRCA1 steady-state protein level in several cell lines. N-acetyl-leu-leu-norleucinal (ALLN), an inhibitor of

BRCA1/2 Reversion Mutations and Cancer Therapy Resistance [PDF]
Germline loss-of-function mutations in BRCA1 and BRCA2 markedly increase susceptibility to breast, ovarian, and other cancers. Mechanistically, BRCA2 facilitates RAD51 recruitment to sites of DNA damage, whereas BRCA1 regulates homologous recombination ...

Methylation of the tumor suppressor protein, BRCA1, influences its transcriptional cofactor function. [PDF]
Approximately half of hereditary breast cancers have mutations in either BRCA1 or BRCA2. BRCA1 is a multifaceted tumor suppressor protein that has implications in processes such as cell cycle, transcription, DNA damage response and chromatin remodeling ...

BRCA1 protein dose-dependent risk for embryonic oxidative DNA damage, embryopathies and neurodevelopmental disorders with and without ethanol exposure [PDF]
Although widely known as a tumor suppressor, the breast cancer 1 susceptibility protein (BRCA1) is also important in development, where it regulates fetal DNA repair pathways that protect against DNA damage caused by physiological and drug-enhanced ...

Heteroduplex and protein truncation analysis of the BRCA1 185delAG mutation [PDF]
We describe a heteroduplex analysis for the detection of the 185delAG mutation in the BRCA1 gene. The protein truncation test (PTT) has previously been used to identify many of the mutations in BRCA1 that result in premature termination of the protein.

Summary: Predicting the risk of cancer mutations is critical for early detection and prevention, but differences in allelic severity of human carriers confound risk predictions.

BAP1: Not just a BRCA1-associated protein [PDF]
BRCA1-Associated Protein 1 (BAP1) is a ubiquitin carboxy-terminal hydrolase that has been established as a tumor suppressor, utilizing its deubiquitinating activity to regulate a number of processes including DNA damage repair, cell cycle control, chromatin modification, programmed cell death, and the immune response.

BRCA1 mediates protein homeostasis through the ubiquitination of PERK and IRE1
Summary: Tumors with BRCA1 mutations have poor prognoses due to genomic instability. Yet this genomic instability has risks and BRCA1-deficient (def) cancer cells must develop pathways to mitigate these risks.

Abnormal expression of BRCA1 and BRCA1‐interactive DNA‐repair proteins in breast carcinomas [PDF]
Breast cancer is one of the most common malignancies among women. The molecular mechanisms involved in breast carcinogenesis, however, remain to be elucidated. Although somatic mutation of BRCA1 is rare, BRCA1 protein expression is reduced in about 30% of sporadic breast carcinomas (Yoshikawa et al., Clin.
