Abstract

BRCA1 is an important gene involved in susceptibility to breast and ovarian cancer and its product regulates the cellular response to DNA double-strand breaks. Here, we present evidence that BRCA1 also contributes to the transcription-coupled repair (TCR) of ultraviolet (UV) light-induced DNA damage. BRCA1 immediately accumulates at the sites of UV irradiation-mediated damage in cell nuclei in a manner that is fully dependent on both Cockayne syndrome B (CSB) protein and active transcription. Suppression of BRCA1 expression inhibits the TCR of UV lesions and increases the UV sensitivity of cells proficient in TCR. BRCA1 physically interacts with CSB protein. BRCA1 polyubiquitinates CSB and this polyubiquitination and subsequent degradation of CSB occur following UV irradiation, even in the absence of Cockayne syndrome A (CSA) protein. The depletion of BRCA1 expression increases the UV sensitivity of CSA-deficient cells. These results indicate that BRCA1 is involved in TCR and that a BRCA1-dependent polyubiquitination pathway for CSB exists alongside the CSA-dependent pathway to yield more efficient excision repair of lesions on the transcribed DNA strand.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • ERCC6 degradation following UV irradiation is more rapid in the absence of USP7 or UVSSA.

    “Furthermore, while ERCC6 is degraded in cells following UV irradiation (Groisman et al., 2006; Wei et al., 2011), this degradation is more rapid in the absence of either protein.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
