The SWI/SNF PBAF complex facilitates REST occupancy at repressive chromatin
By mapping SWI/SNF complex subfamilies in the melanocytic lineage, Grossi and Nguyen
et al. find that PBAF-only sites harbor PRC1/2 modifications and the repressive transcription
factor REST. PBAF is ...

A novel deep learning-based framework reveals a continuum of chromatin sensitivities across transcription factors
The genome-wide binding of many transcription factors (TFs) depends not only on the presence of their recognition motifs, but also on the surrounding chromatin context. This raises the question of how...

Neural crest induction requires SALL4-mediated BAF recruitment to lineage specific enhancers
Neural crest induction begins early during neural plate formation, requiring precise transcriptional control to activate lineage-specific enhancers. Here, we demonstrate that SALL4, a transcription fa...

A lncRNA-mediated metabolic rewiring of cell senescence
Grossi et al. describe how sin-lncRNA interacts with the TCA enzyme DLST to maintain
mitochondrial function and metabolic balance during senescence. Depletion of sin-lncRNA
causes DLST translocation t...

The SWI/SNF PBAF complex facilitates REST occupancy at repressive chromatin
By mapping SWI/SNF complex subfamilies in the melanocytic lineage, Grossi and Nguyen et al. find that PBAF-only sites harbor PRC1/2 modifications and the repressive transcription factor REST. PBAF is necessary for REST to bind its target genes encoding neuronal factors. ARID2-mutant melanomas upregulate REST-controlled transcripts, which correlate with brain metastasis.

A nucleosome switch primes hepatitis B virus infection
A reconstituted cccDNA platform facilitated the discovery of an early chromatinization
event that promotes transcription of the hepatitis B virus (HBV) regulatory X gene.
The use of a small-molecule c...
