The Y-family DNA polymerase κ (pol κ) functions in mammalian nucleotide-excision repair

Ogi, Tomoo, Lehmann, Alan R.·2006·Nature Cell Biology

Abstract

DNA polymerase kappa (pol kappa) is a member of the Y-family of DNA polymerases that are thought to function in translesion synthesis (TLS) past different types of DNA damage. Here, we show that pol kappa-deficient mouse cells have substantially reduced (but not absent) levels of nucleotide excision repair (NER) of UV damage, as measured by several methods. Our results provide evidence for an unexpected role for pol kappa in mammalian NER.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • DNA polymerase κ directly participates in NER repair synthesis in human cells, and loss of TLS activity greatly potentiates the checkpoint response to UV in yeast G1 cells, suggesting closely opposing UV lesions may be at least partly responsible for checkpoint activation.

    “Interestingly, it was recently shown that DNA polymerase κ directly participates to NER repair synthesis in human cells [70,71] and that loss of TLS activity greatly potentiates the checkpoint response to UV irradiation in yeast G1 cells [61], suggesting that closely opposing UV lesions may indeed be at least partly responsible for checkpoint activation.”

  • In human cells, DNA polymerase κ is responsible for approximately 30% of unscheduled DNA synthesis detected in UV-irradiated cells.

    “an unexpected role for TLS polymerases in NER was described in human cells, where DNA polymerase κ was found to be responsible for approximately 30% of the unscheduled DNA synthesis detected in UV-irradiated cells [70,71].”

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.
