In this study, using cryo-EM and in vitro reconstitution, we present the mechanistic basis for the inhibition of cGAS by nucleosomes.

In this review, we discuss how cGAS can be activated by self-DNA, and what is known about the ensuing cellular consequences.


The Cytoplasmic DNA Sensor cGAS Promotes Mitotic Cell Death

Cell, 178 (2019), 302-305

In this study, we show that the innate immune sensor of pathogenic DNA, cGAS, is suppressed on chromatin, but activated under aberrant conditions such as mitotic arrest, where it promotes apoptosis.

Nucleosome functions in spindle assembly and nuclear envelope formation

In this review, we describe the roles that nucleosomes play in orchestrating cellular organisation during the cell cycle.

Nucleosomal regulation of chromatin composition and nuclear assembly revealed by histone depletion

In this study, we showed for the first time the physiological consequences of the absence of nucleosomes. We found that nucleosomes are directly required for assembly of nuclear pore complexes and mitotic spindles.

Survivin reads phosphorylated histone H3 threonine 3 to activate the mitotic kinase Aurora B

Kelly, AE., Ghenoiu, C., Xue, JZ., Zierhut, C., Kimura, H., and Funabiki, H.

Science, 330 (2010), 235-239

In this study, we showed that the association of the mitotic master kinase Aurora B with a mitotic histone phosphorylation triggers its activation.

Break dosage, cell cycle stage and DNA replication influence DNA double strand break response

Zierhut, C., and Diffley, JFX.

EMBO J, 27 (2008), 1875-1885

In this study we describe a method to quantify processing of DSBs. This assay revealed new aspects of eukaryotic break processing, such as cell-cycle regulation and previously unrecognised similarities to prokaryotic break processing. Detailed protocol can be found in Resources.

Mnd1 is required for meiotic interhomolog repair

Curr Biol, 14 (2004), 752–762

This paper contains the functional description of a new DNA repair gene required for meiosis.
