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.

textThe first step in the removal of the flap intermediate is the binding of Replication Protein A (RPA) to the long flap structure. RPA is a eukaryotic single-stranded DNA binding protein (Bae et al. 2001). Binding of RPA to the single strand DNA during telomeric strand displacement synthesis is necessary for the recruitment of DNA2. DNA2 is a helicase/endonuclease that resolves G quadruplexes (G4), which are DNA structures that commonly form in polyguanine-rich telomeric DNA sequences (Masuda-Sasa et al. 2008). DNA2 also removes the initiator RNA primers of Okazaki fragments (Bae et al. 2001).
