Abstract

In transcription-coupled repair, stalled RNA polymerase II (Pol II) is recognized by CSB and CRL4 CSA , which co-operate with UVSSSA and ELOF1 to recruit TFIIH for nucleotide excision repair (TC-NER). To explore the mechanism of TC-NER, we recapitulated this reaction in vitro . When a plasmid containing a site-specific lesion is transcribed in frog egg extract, error-free repair is observed that depends on CSB, CRL4 CSA , UVSSA, and ELOF1. Repair also depends on STK19, a factor previously implicated in transcription recovery after UV exposure. A 1.9 Å cryo-electron microscopy structure shows that STK19 joins the TC-NER complex by binding CSA and the RPB1 subunit of Pol II. Furthermore, AlphaFold predicts that STK19 interacts with the XPD subunit of TFIIH, and disrupting this interface impairs cell-free repair. Molecular modeling suggests that STK19 positions TFIIH ahead of Pol II for lesion verification. In summary, our analysis of cell-free TC-NER suggests that STK19 couples RNA polymerase II stalling to downstream repair events.

  • Another top ranked hit for SLF1 was RAD18, a known SLF1 interactor that was randomly included as part of the 1,000 protein negative set.

    “Notably, in addition to the desired prey SMC6, another top ranked hit for SLF1 was RAD18, a known SLF1 interactor51–53 that was randomly included as part of the 1,000 protein “negative” set.”

    From Predictomes, a classifier-curated database of AlphaFold-modeled protein-protein interactions (2025) · cites this paper as [51]

    The Discussion section describes a screen for STK19 partners, not SLF1, and the Methods section describes SPOC scoring without addressing this claim. Searches for SLF1, RAD18, SMC6, and the 1,000-protein negative set found no passage in our copy establishing that RAD18 is a known SLF1 interactor or describing its inclusion in that set.

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.
