TL;DR: A chromatin-remodeling enzyme, ALC1 (Amplified in Liver Cancer 1, also known as CHD1L), is identified that interacts with poly(ADP-ribose) and catalyzes PARP1-stimulated nucleosome sliding and provides new insights into the mechanisms by which poly(adenosine 5′-diphosphate (ADP)–riboses) regulates DNA repair.
Journal ArticleDOI
BAF complex vulnerabilities in cancer demonstrated via structure-based PROTAC design.
William Farnaby,Manfred Koegl,Michael J. Roy,Claire Whitworth,Emelyne Diers,Nicole Trainor,David Zollman,Steffen Steurer,Jale Karolyi-Oezguer,Carina Riedmueller,Teresa Gmaschitz,Johannes Wachter,Christian Dank,Michael Galant,Bernadette Sharps,Klaus Rumpel,Elisabeth Traxler,Thomas Gerstberger,Renate Schnitzer,Oliver Petermann,Peter Greb,Harald Weinstabl,Gerd Bader,Andreas Zoephel,Alexander Weiss-Puxbaum,Katharina Ehrenhöfer-Wölfer,Simon Wöhrle,Guido Boehmelt,Joerg Rinnenthal,Heribert Arnhof,Nicola Wiechens,Meng-Ying Wu,Tom Owen-Hughes,Peter Ettmayer,Mark Pearson,Darryl B. McConnell,Alessio Ciulli +36 more
TL;DR: Proteolysis targeting chimera (PROTAC) degraders of the BAF ATPase subunits SMARCA2 andSMARCA4 are developed using a bromodomain ligand and recruitment of the E3 ubiquitin ligase VHL to degrade high profile drug targets and induce cancer cell death.
Journal ArticleDOI
DNA repair factor APLF is a histone chaperone.
Pawan Vinod Mehrotra,Dragana Ahel,Daniel P. Ryan,Ria Weston,Nicola Wiechens,Rolf Kraehenbuehl,Tom Owen-Hughes,Ivan Ahel +7 more
TL;DR: It is demonstrated that APLF exhibits histone chaperone activities in a manner that is dependent on its acidic domain and that the NAP1L motif is critical for the repair capacity of APLf in vivo.
Journal ArticleDOI
Sin mutations alter inherent nucleosome mobility
TL;DR: Variation of histone sequence or subtype provides a means by which eukaryotes may regulate access to chromatin through alterations to nucleosome mobility.
Journal ArticleDOI
The Chromatin Remodelling Enzymes SNF2H and SNF2L Position Nucleosomes adjacent to CTCF and Other Transcription Factors.
Nicola Wiechens,Vijender Singh,Triantaffyllos Gkikopoulos,Pieta Schofield,Sonia Rocha,Tom Owen-Hughes +5 more
TL;DR: It is found that the ATP-dependent chromatin remodelling enzyme SNF2H plays a major role organising arrays of nucleosomes adjacent to the binding sites for the architectural transcription factor C TCF sites and acts to promote CTCF binding.
