ProteomicsMechanistic basis of gene regulation by SRCAP and H2A.Z
A central problem in gene regulation is to discriminate gene regulatory functions of chromatin composition from the one of chromatin-modifying complexes. This question has been virtually unexplored in the context of the H2A.Z histone variant and its incorporation into nucleosomes by the Snf2 Related...

ProteomicsMBD2 modulates heterochromatin architecture and composition
Heterochromatin (HC) is essential for nuclear integrity, genome stability, and gene regulation with pericentric heterochromatin (PCH) playing a key role. However, the mechanisms governing PCH compartmentalization remain poorly understood. Recent studies suggest that phase separation (PS) underlies t...

ProteomicsChIP-MS of KAT7, H3K9me3 and H3K4me3 in naive, formative and primed mouse PSCs
The establishment of cellular identity is driven by transcriptional and epigenetic regulation exerted by the components of the chromatin proteome - the chromatome. However, chromatome composition and its dynamics in functional phases of pluripotency have not been comprehensively analyzed thus limiti...

ProteomicsComprehensive chromatin proteomics resolves functional phases of pluripotency and identifies changes in regulatory components
The establishment of cellular identity is driven by transcriptional and epigenetic regulators of the chromatin proteome - the chromatome. Comprehensive analyses of the chromatome composition and dynamics can therefore greatly improve our understanding of gene regulatory mechanisms. Here, we develope...

ProteomicsStreamlined identification of permissive non-canonical amino acid incorporation sites in mammalian cell lines with an expanded genetic code
The genetic code of mammalian cells can be expanded to allow the incorporation of non-canonical amino acids (ncAAs) by suppressing in-frame amber stop codons (UAG) with an orthogonal pyrrolysyl-tRNA synthetase (PylRS)/tRNAPylCUA (PylT) pair. However, the feasibility of this approach is substantially...

ProteomicsChIP-MS of HP1-beta (CBX1) and ubiquitylome of KAP1 (TRIM28) in mESCs
Heterochromatin binding protein HP1β plays an important role in chromatin organization and cell differentiation, however the underlying mechanisms remain unclear. Here, we generated HP1β-/- embryonic stem cells and observed reduced heterochromatin clustering and impaired differentiation. We found th...

ProteomicsDistinct and stage-specific contributions of TET1 and TET2 to stepwise cytosine oxidation in the transition from naive to primed pluripotency
Cytosine DNA bases can be methylated by DNA methyltransferases and subsequently oxidized by TET proteins. The resulting 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC), and 5-carboxylcytosine (5caC) are considered demethylation intermediates as well as stable epigenetic marks. To dissect the ...

Precise regulation of DNA methylation in mammals is critical for genome stability and epigenetic regulation. The discovery of the ten-eleven translocation (TET) proteins catalyzing the oxidation from 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC), and 5-carboxylcyto...

Genome-wide DNA demethylation is a unique feature of mammalian development and naïve pluripotent stem cells. So far, it was unclear how mammals specifically achieve global DNA hypomethylation, given the high conservation of the DNA (de-)methylation machinery among vertebrates. We found that DNA deme...
