Query author contributions in Reactome
Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.
If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

| text | Two DNA helicases XPB (ERCC3) and XPD (ERCC2), which are part of the TFIIH complex, unwind the distorted DNA duplex around the lesion to form an open bubble structure that exposes the damaged site. The helicase activity of the TFIIH complex is stimulated by the presence of XPA and the XPC:RAD23:CETN2 complex (Winkler et al. 2001). The 5'->3' directed helicase activity of ERCC2 (Kuper et al. 2012) is crucial for unwinding of the distorted dsDNA during nucleotide excision repair (NER) (Coin et al. 2007). The 3'->5' directed DNA helicase ERCC3 contributes to dsDNA unwinding during NER through ATP hydrolysis (Coin et al. 2007). In addition to DNA unwinding, ERCC2 and ERCC3 verify the presence of DNA damage (Oksenych et al. 2009, Mathieu et al. 2010, Mathieu et al. 2013). Verification of DNA damage also involves XPA (Camenisch et al. 2006). The binding site of XPC determines which DNA strand is selected by ERCC2 to verify the presence of lesions (Sugasawa et al. 2009). |
