Abstract
Zinc-finger ubiquitin-binding domains (ZnF-UBDs) are noncatalytic domains mostly found in deubiquitylases (DUBs) such as USP3. They represent an underexplored opportunity for the development of deubiquitylase-targeting chimeras (DUBTACs) to pharmacologically induce the deubiquitylation of target proteins. We previously showed that ZnF-UBDs are ligandable domains. Here, a focused small molecule library screen against a panel of 11 ZnF-UBDs led to the identification of compound 59, a ligand engaging the ZnF-UBD of USP3 with a KD of 14 μM. The compound binds the expected C-terminal ubiquitin binding pocket of USP3 as shown by hydrogen-deuterium exchange mass spectrometry experiments and does not inhibit the cleavage of K48-linked diubiquitin by USP3. As such, this molecule is a chemical starting point toward chemical tools that could be used to interrogate the function of the USP3 Znf-UBD and the consequences of recruiting USP3 to ubiquitylated proteins.

BAF Complex Maintains Glioma Stem Cells in Pediatric H3K27M Glioma. Cancer Discov 2022; 12:2880-2905. [PMID: 36305736 PMCID: PMC9716260 DOI: 10.1158/2159-8290.cd-21-1491] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 08/03/2022] [Accepted: 09/15/2022] [Indexed: 01/12/2023]
Abstract
Diffuse midline gliomas are uniformly fatal pediatric central nervous system cancers that are refractory to standard-of-care therapeutic modalities. The primary genetic drivers are a set of recurrent amino acid substitutions in genes encoding histone H3 (H3K27M), which are currently undruggable. These H3K27M oncohistones perturb normal chromatin architecture, resulting in an aberrant epigenetic landscape. To interrogate for epigenetic dependencies, we performed a CRISPR screen and show that patient-derived H3K27M-glioma neurospheres are dependent on core components of the mammalian BAF (SWI/SNF) chromatin remodeling complex. The BAF complex maintains glioma stem cells in a cycling, oligodendrocyte precursor cell-like state, in which genetic perturbation of the BAF catalytic subunit SMARCA4 (BRG1), as well as pharmacologic suppression, opposes proliferation, promotes progression of differentiation along the astrocytic lineage, and improves overall survival of patient-derived xenograft models. In summary, we demonstrate that therapeutic inhibition of the BAF complex has translational potential for children with H3K27M gliomas. SIGNIFICANCE Epigenetic dysregulation is at the core of H3K27M-glioma tumorigenesis. Here, we identify the BRG1-BAF complex as a critical regulator of enhancer and transcription factor landscapes, which maintain H3K27M glioma in their progenitor state, precluding glial differentiation, and establish pharmacologic targeting of the BAF complex as a novel treatment strategy for pediatric H3K27M glioma. See related commentary by Beytagh and Weiss, p. 2730. See related article by Mo et al., p. 2906.
