The nascent RNA binding complex SFiNX licenses piRNA-guided heterochromatin formation
The PIWI-interacting RNA (piRNA) pathway protects genome integrity in part through establishing repressive heterochromatin at transposon loci. Silencing requires piRNA-guided targeting of nuclear PIWI proteins to nascent transposon transcripts, yet the ...

Chromatin machinery influences how DNA is ‘wrapped’ around histones in the nucleosome of immune and brain cells. Plain language summary: https://onlinelibrary.wiley.com/doi/10.1111/dmcn.16299 Abstract We report eight children with de novo pathogenic DNA variants in chromatin‐related genes: MORC2, CHD7, KANSL1, KMT2D, ZMYND11, HIST1HIE, EP300, and KMT2B.

Nucleation and spreading of a heterochromatic domain in fission yeast
Chromosomes contain large heterochromatin domains. Here, the authors measure the kinetics of heterochromatin formation in fission yeast and show both global and local feedbacks by nucleosome-bound enzymes are important for formation and stability of the ...

A self-organised liquid reaction container for cellular memory [PDF]
Epigenetic inheritance during cell division is essential for preserving cell identity by stabilizing the overall chromatin organisation. Heterochromatin,the condensed and transcriptionally silent fraction of chromatin,is marked by specific epigenetic modifications that are diluted during each cell division.

Dynamics of BAF- Polycomb Complex Opposition on Heterochromatin in Normal and Oncogenic States
The opposition between Polycomb repressive complexes (PRCs) and BAF (mSWI/SNF) complexes has a critical role in both development and disease. Mutations in the genes encoding BAF subunits contribute to more than 20% of human malignancies, yet the ...

The silencing of transposable elements is mediated by piRNAs through post‐transcriptional and transcriptional regulation. In Drosophila, piRNAs are processed within unique non‐membrane structures: nuage in germline cells and Yb bodies in somatic gonadal cells.

Versatile roles of disordered transcription factor effector domains in transcriptional regulation
Disordered effector domains (EDs) of transcription factors (TFs) play versatile roles in transcriptional regulation. These include mediating protein–protein interactions with protein complexes like, facilitating condensate formation to enhance transcriptional efficiency, modulating DNA‐binding specificity through genome scanning, and serving as hubs ...

Under normoxic conditions, the SUMOylated fraction of TFAP2A cannot interact with the Ku70/Ku80 complex, nor it can bind to chromatin. The unSUMOylated fraction pre‐occupies the chromatin of a subset of hypoxia‐induced genes together with the Ku70/Ku80 complex for basal euchromatin formation. Under hypoxic conditions, the SUMOylation equilibrium shifts
