Abstract

Rad18 functions at the cross-roads of three different DNA damage response (DDR) pathways involved in protecting stressed replication forks: homologous recombination repair, DNA inter-strand cross-link repair and DNA damage tolerance. Although Rad18 serves to facilitate replication of damaged genomes by promoting translesion synthesis (TLS), this comes at a cost of potentially error-prone lesion bypass. In contrast, loss of Rad18-dependent TLS potentiates the collapse of stalled forks and leads to incomplete genome replication. Given the pivotal nature with which Rad18 governs the fine balance between replication fidelity and genome stability, Rad18 levels and activity have a major impact on genomic integrity. Here, we identify the de-ubiquitylating enzyme USP7 as a critical regulator of Rad18 protein levels. Loss of USP7 destabilizes Rad18 and compromises UV-induced PCNA mono-ubiquitylation and Pol η recruitment to stalled replication forks. USP7-depleted cells also fail to elongate nascent daughter strand DNA following UV irradiation and show reduced DNA damage tolerance. We demonstrate that USP7 associates with Rad18 directly via a consensus USP7-binding motif and can disassemble Rad18-dependent poly-ubiquitin chains both in vitro and in vivo. Taken together, these observations identify USP7 as a novel component of the cellular DDR involved in preserving the genome stability.

  • USP7 has a role in the initial stages of both translesion synthesis and template switching.

    “Recent reports have suggested that USP7 has a role in the initial stages of both translesion synthesis and template switching.”

  • Depleting USP7 decreases protein levels of Rad18 and HLTF, suppresses PCNA mono- and polyubiquitination, and reduces Pol η foci formation in UV irradiated cells.

    “Indeed, depleting USP7 from cells was found to decrease the protein levels of Rad18 and HLTF, suppress PCNA mono and polyubiquitination, as well as reduce Pol η foci formation in UV irradiated cells.”

  • USP7 indirectly influences PCNA monoubiquitination by regulating the stability of Rad18 and HLTF E3 ubiquitin ligases.

    “In addition, USP7 has been suggested to indirectly influence PCNA mono-ubiqutination, by regulating the stability of the Rad18 and HLTF E3 ubiquitin ligases (Qing et al., 2011; Zlatanou et al., 2016).”

  • Pol η protein levels appeared unchanged following siRNA-mediated depletion of USP7 in a subsequent publication.

    “It should be noted, however, that despite the attractive elegance of this proposed model, these claims have been contradicted by a subsequent publication, where Pol η protein levels appeared unchanged following siRNA-mediated depletion of USP7 (Zlatanou et al., 2016).”

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.
