Abstract

Complementation group C of xeroderma pigmentosum (XP) represents one of the most common forms of this cancer-prone DNA repair syndrome. The primary defect is located in the subpathway of the nucleotide excision repair system, dealing with the removal of lesions from the non-transcribing sequences ('genome-overall' repair). Here we report the purification to homogeneity and subsequent cDNA cloning of a repair complex by in vitro complementation of the XP-C defect in a cell-free repair system containing UV-damaged SV40 minichromosomes. The complex has a high affinity for ssDNA and consists of two tightly associated proteins of 125 and 58 kDa. The 125 kDa subunit is an N-terminally extended version of previously reported XPCC gene product which is thought to represent the human homologue of the Saccharomyces cerevisiae repair gene RAD4. The 58 kDa species turned out to be a human homologue of yeast RAD23. Unexpectedly, a second human counterpart of RAD23 was identified. All RAD23 derivatives share a ubiquitin-like N-terminus. The nature of the XP-C defect implies that the complex exerts a unique function in the genome-overall repair pathway which is important for prevention of skin cancer.

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?

  • The hHR23B-XPC complex, or XPC alone, binds UV-induced single-stranded and double-stranded DNA with similar high affinity, prefers DNA containing various lesions, and can bind small bubble structures with or without a lesion.

    “hHR23B-XPC complex or only XPC exhibits a similar high affinity for both UV-induced single-stranded DNA (ssDNA) and double-stranded DNA (dsDNA) [230, 259], preferentially binds to DNA with various lesions [259] and even to small bubble structures with or without a lesion [260].”

    From Molecular Mechanisms of Ultraviolet Radiation‐Induced DNA Damage and Repair (2010) · cites this paper as [230]

    The Results report that the XP-C–HHR23B complex bound strongly to a single-stranded DNA-cellulose column. The Discussion says this indicates high affinity for ssDNA but explicitly leaves open which component is responsible. The paper does not establish similarly high affinity for UV-damaged double-stranded DNA or for XPC alone; the citing sentence assigns the lesion and bubble claims to other references. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • hHR23A and hHR23B each carry a ubiquitin-like domain at their amino terminus.

    “Both hHR23A and -B harbor a ubiquitin-like moiety at their amino terminus [230].”

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.
