CCDC98 targets BRCA1 to DNA damage sites

Liu, Zixing, Wu, Jiaxue, Yu, Xiaochun·2007·Nature Structural & Molecular Biology

Abstract

Breast cancer-1 (BRCA1) participates in the DNA damage response. However, the mechanism by which BRCA1 is recruited to DNA damage sites remains elusive. Recently, we have demonstrated that a ubiquitin-binding protein, RAP80, is required for DNA damage-induced BRCA1 translocation. Here we identify another component, CCDC98, in the BRCA1-RAP80 complex. CCDC98 mediates BRCA1's association with RAP80. Moreover, CCDC98 controls both DNA damage-induced formation of BRCA1 foci and BRCA1-dependent G2/M checkpoint activation. Together, our results demonstrate that CCDC98 is a BRCA1 binding partner that mediates BRCA1 function in response to DNA damage.

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

  • Abraxas, Bach1, and CtIP directly interact with BRCA1 BRCT domains through the pSPxF motif in a phosphorylation-dependent manner, forming mutually exclusive A, B, and C complexes.

    “Three proteins, Abraxas (also known as Abra1, FAM175A, CCDC98), Bach1 (also known as Brip1, FancJ) and CtIP (also known as RBBP8), directly interact with the BRCA1 BRCT domains through the pSPxF motif in a phosphorylation-dependent manner forming mutually exclusive complexes, which were thus named as the A, B and C complexes of BRCA1 (Greenberg et al., 2006; Kim et al., 2007; Liu et al., 2007;”

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.
