Journal ArticleDOI
Mre11–Rad50–Nbs1 conformations and the control of sensing, signaling, and effector responses at DNA double-strand breaks
TL;DR: MRN can be considered as a molecular computer that effectively assesses optimal responses and pathway choice based upon its states as set by cell status and the nature of the DNA damage and is proposed to be possible because each MRN subunit can exist in three or more distinct states.
Journal ArticleDOI
Enhancement of RAD51 recombinase activity by the tumor suppressor PALB2
Eloise Dray,Julia Etchin,Claudia Wiese,Dorina Saro,Gareth J. Williams,Michal Hammel,Xiong Yu,Vitold E. Galkin,Dongqing Liu,Miaw-Sheue Tsai,Shirley M.-H. Sy,Shirley M.-H. Sy,David Schild,Edward H. Egelman,Junjie Chen,Patrick Sung +15 more
TL;DR: This work documents a new function of PALB2: to enhance RAD51's ability to form the D loop, and demonstrates the multifaceted role of PALb2 in chromosome damage repair.
Journal ArticleDOI
ABC ATPase signature helices in Rad50 link nucleotide state to Mre11 interface for DNA repair
Gareth J. Williams,R. Scott Williams,R. Scott Williams,Jessica S. Williams,Jessica S. Williams,Gabriel Moncalián,Gabriel Moncalián,Andrew S. Arvai,Oliver Limbo,Grant Guenther,Soumita SilDas,Michal Hammel,Paul Russell,John A. Tainer +13 more
TL;DR: These new results characterize flexible ATP-dependent Mre11 regulation, defects in cancer-linked RBD mutations, conserved superfamily basic switches and motifs effecting ATP-driven conformational change, and they provide a unified comprehension of ABC–ATPase activities.
Journal ArticleDOI
ATP-driven Rad50 conformations regulate DNA tethering, end resection, and ATM checkpoint signaling.
Rajashree A. Deshpande,Gareth J. Williams,Oliver Limbo,R. Scott Williams,Jeff Kuhnlein,Ji-Hoon Lee,Scott Classen,Grant Guenther,Paul Russell,John A. Tainer,John A. Tainer,Tanya T. Paull +11 more
TL;DR: Crystal structures, X‐ray scattering, biochemical assays, and functional analyses of mutant PfRad50 complexes show that the ATP‐induced ‘closed’ conformation promotes DNA end binding and end tethering, while hydrolysis‐induced opening is essential for DNA resection.
Journal ArticleDOI
A novel Fanconi anaemia subtype associated with a dominant-negative mutation in RAD51
Najim Ameziane,Patrick May,Anneke Haitjema,Henri J. van de Vrugt,Henri J. van de Vrugt,Sari E. van Rossum-Fikkert,Dejan Ristic,Gareth J. Williams,Jesper A. Balk,Davy A.P. Rockx,Hong Li,Martin A.

TL;DR: The results point to an important role for RAD51-mediated homologous recombination in neurodevelopment, in addition to DNA repair and cancer susceptibility, as well as a dominant-negative mutation in an FA-like patient.
