Of the four potential phosphoacceptor sites in the BRCA1 (1005–1313) fragment (Ser 1143, Ser 1239, Ser 1280, Ser 1298), Ala substitutions at two sites, Ser 1143 and Ser 1280, reduced the in vitro phosphorylation of GST–BRCA1 (1005–1313) by ATR, whereas substitution of Ser 1239 or Ser 1298 with Ala had little or no effect (Fig. 2C; data not shown). A Ser 1143/Ser 1280 double mutant was a poor substrate for ATR, suggesting that these are the two major in vitro phosphorylation sites on this BRCA1 fragment. | Together, these results demonstrate that ATR and BRCA1 are components of the same genotoxic stress-responsive pathway, and that ATR directly phosphorylates BRCA1 in response to damaged DNA or stalled DNA replication. |

Although no single mutation eliminated the GST–BRCA1 (1314–1863) electrophoretic mobility shift, a quadruple mutant (GST–BRCA14A) containing Ala substitutions at Ser 1387, Thr 1394, Ser 1423, and Ser 1457 showed no alteration in electrophoretic mobility after phosphorylation by ATR-containing immune complexes (Fig.2D). The total incorporation of 32Pi into the GST–BRCA14Asubstrate was reduced by 70% relative to that obtained with wild-type GST–BRCA1 (1314–1863), suggesting that these four residues account for most, but not all of the phosphorylation sites in this fragment. | Together, these results demonstrate that ATR and BRCA1 are components of the same genotoxic stress-responsive pathway, and that ATR directly phosphorylates BRCA1 in response to damaged DNA or stalled DNA replication. |

Phosphorylation of serine 1387 in brca1 is specifically required for the atm-mediated s-phase checkpoint after ionizing irradiation.We recently reported that brca1 function is required for appropriate cell cycle arrests after ionizing irradiation in both the s-phase and the g2 phase of the cell cycle. We also found that mutation of serine 1423 in brca1, a target of atm phosphorylation, abrogates the g2-m checkpoint but not the ionizing irradiation-induced s-phase checkpoint. Here we demonstrate that mutation of serine 1387 in brca1, another target of atm phosphorylation, conversely abrogates the radiation-induced s-phase arrest but does not affect the g2-m checkpoint. |

The brca1 (breast cancer gene 1) tumor suppressor protein is phosphorylated in response to dna damage. Results from this study indicate that the checkpoint protein kinase atm (mutated in ataxia telangiectasia) was required for phosphorylation of brca1 in response to ionizing radiation. Atm resides in a complex with brca1 and phosphorylated brca1 in vivo and in vitro in a region that contains clusters of serine-glutamine residues. Phosphorylation of this domain appears to be functionally important because a mutated brca1 protein lacking two phosphorylation sites failed to rescue the radiation hypersensitivity of a brca1-deficient cell line.Atm-dependent phosphorylation of ser1423 or ser1524 also occurred in vivo, |

Herein, we demonstrate that Fyn-related kinase (Frk)/Rak plays an important role in maintaining genomic stability, possibly in part through positively regulating BRCA1 protein stability and function via tyrosine phosphorylation on BRCA1 Tyr1552. Rak-mediated tyrosine phosphorylation of BRCA1 is essential for its stability and function |

Here, we show that the Ku70/Ku80 heterodimer binds with topoI, and that the DNA-dependent protein kinase (DNA-PKcs) phosphorylates topoI on serine 10 (topoI-pS10), which is subsequently ubiquitinated by BRCA1. Taken together, we conclude that BRCA1 is the E3 ligase for topoI, and the rate of topoI proteasomal degradation determines CPT response. |

In conclusion, our data show that ctip is a physiological substrate of the brca1 e3 ligase. Brca1 recruits ctip through its c-terminal brct domains and promotes ctip ubiquitination through its n-terminal ring domain. The ubiquitinated ctip is not targeted for degradation. Instead, ubiquitinated ctip binds to chromatin following dna damage and is likely to be involved in dna damage checkpoint control. |

The major genetic evidence supporting ubiquitin ligase function for BRCA1 in vivo comes from studies on the FANCD2 protein. Whereas in wild‐type cells the FANCD2 protein co‐localizes with BRCA1 in nuclear foci and becomes monoubiquitylated in response to DNA damage, HCC1937 cells, which encode a mutated form of BRCA1, are largely defective for both monoubiquitylation of FANCD2 and foci formation |

We demonstrate that this BRCA1-GATA3 repression complex is not a FOXC1-specific phenomenon as a number of other genes associated with BLBCs such as FOXC2, CXCL1 and p-cadherin were also repressed in a similar manner. |

BRCA1 encodes a tumor suppressor that is mutated in familial breast and ovarian cancers. Here, it is shown that BRCA1 interacts in vitro and in vivo with hRad50, which forms a complex with hMre11 and p95/nibrin. Upon irradiation, BRCA1 was detected in discrete foci in the nucleus, which colocalize with hRad50.| These data suggest that BRCA1 is important for the cellular responses to DNA damage that are mediated by the hRad50-hMre11-p95 complex. |
