Structural basis of SIRT7 nucleosome engagement and substrate specificity

Esther Calvino Sanles, Polina Nikolaeva Foteva, Henning Paul-Julius Stahlberg, Beat Fierz, Dongchun Ni, Babatunde Edukpe Ekundayo, Carlos Moreno Yruela

Chromatin-modifying enzymes target distinct residues within histones to finetune gene expression profiles. SIRT7 is an NAD+-dependent deacylase often deregulated in cancer, which deacetylates either H3 lysine 36 (H3K36) or H3K18 with high specificity withi ...

Nucleosome Binding by the Lysine Specific Demethylase 1 (LSD1) Enzyme Enables Histone H3 Demethylation

Beat Fierz, Aurore Marie-France Delachat

The essential human enzyme lysine specific demethylase 1 (LSD1) silences genes by demethylating mono- and dimethylated lysine 4 in histone H3 (H3K4me1/2). Studies of the minimal requirements for LSD1 activity are complicated by the heterogeneity of histone ...

Dynamic chromatin technologies: from individual molecules to epigenomic regulation in cells

Beat Fierz

The establishment and maintenance of chromatin states involves multiscale dynamic processes integrating transcription factor and multiprotein effector dynamics, cycles of chemical chromatin modifications, and chromatin structural organization. Recent devel ...

Torsin ATPases influence chromatin interaction of the Torsin regulator LAP1

Beat Fierz, Rudolf Hovius

The inner nuclear membrane is functionalized by diverse transmembrane proteins that associate with nuclear lamins and/or chromatin. When cells enter mitosis, membrane-chromatin contacts must be broken to allow for proper chromosome segregation; yet how thi ...

KAP1 is an antiparallel dimer with a functional asymmetry

Didier Trono, Matteo Dal Peraro, Beat Fierz, Davide Demurtas, Louise Catherine Bryan, Maria Josefina Marcaida Lopez, Giulia Fonti, Pierre-Yves Joseph Laurent Helleboid, Alexandra Styliani Kalantzi

KAP1 (KRAB domain-associated protein 1) plays a fundamental role in regulating gene expression in mammalian cells by recruiting different transcription factors and altering the chromatin state. In doing so, KAP1 acts both as a platform for macromolecular i ...

BAF restricts cGAS on nuclear DNA to prevent innate immune activation

Beat Fierz, Mahmut Selman Sakar, Andrea Ablasser, Murat Kaynak, Kristina Makasheva, Alexiane Clara Decout, Baptiste Claude André Guey, Marilena Wischnewski

The appearance of DNA in the cytosol is perceived as a danger signal that stimulates potent immune responses through cyclic guanosine monophosphate–adenosine monophosphate synthase (cGAS). How cells regulate the activity of cGAS toward self-DNA and guard a ...

A Modular Ligation Strategy for Asymmetric Bivalent Nucleosomes Trimethylated at K36 and K27

Beat Fierz, Nora Guidotti, Andreas Linus Bachmann, Carolin Christine Lechner

In nature, individual histones in the same nucleosome can carry identical (symmetric) or different (asymmetric) post-translational modification (PTM) patterns, increasing the combinatorial complexity. Embryonic stem cells exhibit bivalent nucleosomes, some ...

Multivalent Peptide Ligands To Probe the Chromocenter Microenvironment in Living Cells

Beat Fierz, Pablo Rivera Fuentes, Nora Guidotti, Maxime Nicolas Mivelaz, Adam Miklos Eördögh

Chromatin is spatially organized into functional states that are defined by both the presence of specific histone post-translational modifications (PTMs) and a defined set of chromatin-associated “reader” proteins. Different models for the underlying mecha ...

DNA binding by PHF1 prolongs PRC2 residence time on chromatin and thereby promotes H3K27 methylation

Beat Fierz, Andreas Linus Bachmann

Polycomb repressive complex 2 (PRC2) trimethylates histone H3 at lysine 27 to mark genes for repression. We measured the dynamics of PRC2 binding on recombinant chromatin and free DNA at the single-molecule level using total internal reflection fluorescenc ...

Traceless Synthesis of Asymmetrically Modified Bivalent Nucleosomes

Beat Fierz, Carolin Christine Lechner, Ninad Dilip Agashe

Nucleosomes carry extensive post-translational modifications (PTMs), which results in complex modification patterns that are involved in epigenetic signaling. Although two copies of each histone coexist in a nucleosome, they may not carry the same PTMs and ...

A two-state activation mechanism controls the histone methyltransferase Suv39h1

Beat Fierz

Specialized chromatin domains contribute to nuclear organization and regulation of gene expression. Gene-poor regions are di- and trimethylated at lysine 9 of histone H3 (H3K9me2 and H3K9me3) by the histone methyltransferase Suv39h1. This enzyme harnesses ...

Cooperation between bHLH transcription factors and histones for DNA access

Beat Fierz, Kristina Makasheva

The basic helix-loop-helix (bHLH) family of transcription factors recognizes DNA motifs known as E-boxes (CANNTG) and includes 108 members(1). Here we investigate how chromatinized E-boxes are engaged by two structurally diverse bHLH proteins: the proto-on ...

Chromatin Fiber Invasion and Nucleosome Displacement by the Rap1 Transcription Factor

Rudolf Hovius, Beat Fierz, Iuliia Boichenko, Maxime Nicolas Mivelaz, Anne-Marinette Thi Phuong Hanh Cao

Pioneer transcription factors (pTFs) bind to target sites within compact chromatin, initiating chromatin remodeling and controlling the recruitment of downstream factors. The mechanisms by which pTFs overcome the chromatin barrier are not well understood. ...

PR-DUB preserves Polycomb repression by preventing excessive accumulation of H2Aub1, an antagonist of chromatin compaction

Beat Fierz, Iuliia Boichenko

The Polycomb repressive complexes PRC1, PRC2, and PR-DUB repress target genes by modifying their chromatin. In Drosophila, PRC1 compacts chromatin and monoubiquitinates histone H2A at lysine 118 (H2Aub1), whereas PR-DUB is a major H2Aub1 deubiquitinase, bu ...
