Journal ArticleDOI

Tumor suppressor and deubiquitinase BAP1 promotes DNA double-strand break repair.

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

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

The BAP1/ASXL2 Histone H2A Deubiquitinase Complex Regulates Cell Proliferation and is Disrupted in Cancer

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.
