Abstract
- BRCA1 dysfunction sensitizes cancer cells to PARP inhibitors (PARPi) but the underlying mechanism is unclear. Here, the authors identify RNF19A as a determinant of PARPi sensitivity, showing that RNF19A ubiquitinates BARD1, negatively regulates the BRCA1-BARD1 complex, and inhibits homologous recombination.
