Journal ArticleDOI
Tumor suppressor and deubiquitinase BAP1 promotes DNA double-strand break repair.
Helen Yu,Helen Pak,Ian Hammond-Martel,Mehdi Ghram,Amélie Rodrigue,Salima Daou,Haithem Barbour,Luc Corbeil,Josée Hébert,Elliot Drobetsky,Jean-Yves Masson,Javier M. Di Noia,El Bachir Affar +12 more
TL;DR: It is shown that BAP1 is recruited to double-strand DNA break sites and promotes error-free repair of these lesions, providing the first evidence that phosphorylation coordinates the function of B AP1 in promoting cellular recovery from DNA damage.
Journal ArticleDOI
The Ubiquitin Carboxyl Hydrolase BAP1 Forms a Ternary Complex with YY1 and HCF-1 and Is a Critical Regulator of Gene Expression
Helen Yu,Nazar Mashtalir,Salima Daou,Ian Hammond-Martel,Julie Ross,Guangchao Sui,Gerald W. Hart,Frank J. Rauscher,Elliot Drobetsky,Eric Milot,Yang Shi,El Bachir Affar +11 more
TL;DR: The findings establish a direct link between BAP1 and the transcriptional control of genes regulating cell growth and proliferation and shed light on a novel mechanism of transcription regulation involving ubiquitin signaling.
Journal ArticleDOI
Genome-Wide CRISPR-Cas9 Screens Expose Genetic Vulnerabilities and Mechanisms of Temozolomide Sensitivity in Glioblastoma Stem Cells.
Graham MacLeod,Danielle Bozek,Nishani Rajakulendran,Vernon Monteiro,Moloud Ahmadi,Zachary Steinhart,Michelle Kushida,Helen Yu,Fiona J. Coutinho,Florence M.G. Cavalli,Ian Restall,Xiaoguang Hao,Traver Hart,H. Artee Luchman,Samuel Weiss,Peter B. Dirks,Stephane Angers +16 more
TL;DR: Using CRISPR-Cas9 approaches in patient-derived GBM stem cells to interrogate function of the coding genome, actionable pathways responsible for growth are identified, which reveal the gene-essential circuitry of G BM stemness and proliferation.
Journal ArticleDOI
The BAP1/ASXL2 Histone H2A Deubiquitinase Complex Regulates Cell Proliferation and is Disrupted in Cancer
Salima Daou,Ian Hammond-Martel,Nazar Mashtalir,Haithem Barbour,Jessica Gagnon,Nicholas V G Iannantuono,Nadine Sen Nkwe,Alena Motorina,Helen Pak,Helen Yu,Hugo Wurtele,Eric Milot,Frédérick A. Mallette,Michele Carbone,El Bachir Affar +14 more
TL;DR: BAP1 forms two mutually exclusive complexes with the transcriptional regulators ASXL1 and ASXL2, which are necessary for maintaining proper protein levels of this DUB, and it is demonstrated that BAP1 interaction with AsXL2 regulates cell senescence and that AS XL2 cancer-associated mutations disrupt B AP1 DUB activity.
Journal ArticleDOI
Roles of ubiquitin signaling in transcription regulation.
TL;DR: This review summarizes current findings on the critical functions exerted by E3s and DUBs in transcriptional control, particularly chromatin remodeling and transcription initiation/elongation.
