BRCA1 deficiencies cause breast, ovarian and other cancers, and render tumours hypersensitive to PARP-inhibitors. To understand resistance mechanisms, we conducted whole-genome CRISPR-Cas9 synthetic-viability/resistance screens in BRCA1-deficient breast cancer cells treated with PARP-inhibitors. Thu...
Shieldin complex promotes DNA end joining and counters homologous recombination in BRCA1-null cells: Immunoprecipitation-mass spectrometric analysis of protein interactors of GFP-C20orf196 and GFP-FAM35A
53BP1 governs a specialized, context-specific branch of the classical non-homologous end joining DNA double-strand break repair pathway. Mice lacking 53bp1 (also known as Trp53bp1) are immunodeficient owing to a complete loss of immunoglobulin class-switch recombination, and reduced fidelity of long...
