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

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

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 ...

Dynamic protein-chromatin interactions in heterochromatin and during the DNA damage response on the single molecule level

Andreas Linus Bachmann

Dynamic regulation of chromatin, a structure consisting of DNA and histone proteins, is mediated through histone post-translational modifications (PTMs) and effector proteins. HP1a and PRC2 are recruited to repressive PTMs (H3K9me3, H3K27me3) and enable he ...

Single-molecule kinetic analysis of HP1-chromatin binding reveals a dynamic network of histone modification and DNA interactions

Vassily Hatzimanikatis, Louise Catherine Bryan, Georg Fantner, Pascal Damian Odermatt, Oliver Hantschel, Sandrine Madeleine Suzanne Georgeon, Beat Fierz, Sinan Kilic, Carolin Christine Lechner, Andreas Linus Bachmann, Daniel Robert Weilandt

Chromatin recruitment of effector proteins involved in gene regulation depends on multivalent interaction with histone post-translational modifications (PTMs) and structural features of the chromatin fiber. Due to the complex interactions involved, it is c ...

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 ...

Multivalency governs HP1α association dynamics with the silent chromatin state

Louise Catherine Bryan, Beat Fierz, Sinan Kilic, Andreas Linus Bachmann

Multivalent interactions between effector proteins and histone post-translational modifications are an elementary mechanism of dynamic chromatin signalling. Here we elucidate the mechanism how heterochromatin protein 1α (HP1α), a multivalent effector, is e ...
