Abstract

Human DNA repair excision nuclease removes DNA damage by incising on both sides of the lesion in a precise manner. The activity requires participation of 16-17 polypeptides. Of these, the XPF.ERCC1 complex and XPG were predicted to carry the nuclease active sites based on studies with the recombinant proteins and the yeast homologs of these proteins. Furthermore, recent work with model (undamaged) substrates have led to predictions of the roles of these proteins in incising 5' or 3' to the lesion. We have used damaged DNA substrates and antibodies to XPG and ERCC1 to test these predictions. Our results reveal that anti-XPG antibodies change the site of 3' incision and at high concentration inhibit the 3' incision without significantly affecting the 5' incision, indicating that XPG makes the 3' incision and further that under this condition 5' incision can occur without 3' incision. In contrast, anti-ERCC1 antibodies inhibit both the 3' and 5' incisions. Using a defined system for excision repair we also demonstrate that the 3' incision can occur without the 5' incision, leading us to conclude that under certain conditions the two incisions can occur independently.

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.
