The human HELQ helicase and XRN2 exoribonuclease cooperate in R-loop resolution (2024)
Journal Article
Pan, J., Betts, H., Cubbon, A., Bolt, E., Soultanas, P., & He, L. (in press). The human HELQ helicase and XRN2 exoribonuclease cooperate in R-loop resolution. Open Biology,

The human HELQ helicase is a superfamily 2, 3’-5’ helicase homologous to POLQ and RNA helicases of the Ski2-like subfamily. It is involved in diverse aspects of DNA repair and is an emerging prognosis biomarker and novel drug-target for cancer therap...

Interaction of human HelQ with DNA polymerase delta halts DNA synthesis and stimulates DNA single-strand annealing (2023)
Journal Article
He, L., Lever, R., Cubbon, A., Tehseen, M., Jenkins, T., Nottingham, A. O., Horton, A., Betts, H., Fisher, M., Hamdan, S. M., Soultanas, P., & Bolt, E. L. (2023). Interaction of human HelQ with DNA polymerase delta halts DNA synthesis and stimulates DNA single-strand annealing. Nucleic Acids Research, 51(4), 1740-1749. https://doi.org/10.1093/nar/gkad032

DNA strand breaks are repaired by DNA synthesis from an exposed DNA end paired with a homologous DNA template. DNA polymerase delta (Pol δ) catalyses DNA synthesis in multiple eukaryotic DNA break repair pathways but triggers genome instability unles...

The HelQ human DNA repair helicase utilizes a PWI-like domain for DNA loading through interaction with RPA, triggering DNA unwinding by the HelQ helicase core (2021)
Journal Article
Jenkins, T., Northall, S. J., Ptchelkine, D., Lever, R., Cubbon, A., Betts, H., Taresco, V., Cooper, C. D. O., McHugh, P. J., Soultanas, P., & Bolt, E. L. (2021). The HelQ human DNA repair helicase utilizes a PWI-like domain for DNA loading through interaction with RPA, triggering DNA unwinding by the HelQ helicase core. NAR Cancer, 3(1), Article zcaa043. https://doi.org/10.1093/narcan/zcaa043

Genome instability is a characteristic enabling factor for carcinogenesis. HelQ helicase is a component of human DNA maintenance systems that prevent or reverse genome instability arising during DNA replication. Here, we provide details of the molecu...

DNA binding and unwinding by Hel308 helicase requires dual functions of a winged helix domain (2017)
Journal Article
Northall, S. J., Buckley, R., Jones, N., Penedo, J. C., Soultanas, P., & Bolt, E. L. (2017). DNA binding and unwinding by Hel308 helicase requires dual functions of a winged helix domain. DNA Repair, 57, https://doi.org/10.1016/j.dnarep.2017.07.005

Hel308 helicases promote genome stability linked to DNA replication in archaea, and have homologues in metazoans. In the crystal structure of archaeal Hel308 bound to a tailed DNA duplex, core helicase domains encircle single-stranded DNA (ssDNA) in...
