To probe gene-scale chromatin physics, we built 96-mer (20 kb) arrays with defined histone marks. Combining single-molecule tracking, AFM imaging, and developing in vitro Hi-C, we saw how specific modifications dictate chromatin structure and dynamics. www.science.org/doi/10.1126/...

Gene-scale in vitro reconstitution reveals histone acetylation directly controls chromatin architecture

Reconstituting 20-kb chromatin shows that tuning acetylation alone reshapes its folding, dynamics, and contact domain formation.

1/ Excited to share our new study with @brumbaugh-lab.bsky.social, out in @natbiotech.nature.com! P-bodies selectively sequester RNAs encoding cell fate regulators, often from the preceding developmental stage. Releasing these RNAs can drive changes in cell identity. 🧵 www.nature.com/articles/s41...

Our review on cell cycle – cell fate (de)coupling is out! doi.org/10.1242/dev.... Was a lot of fun writing this with Allon Klein, reading old papers(earliest from 1902), and speculating on why cell cycle progression is not necessary for differentiation across many many tissues and species. (1/3)

Coupling and decoupling of the cell cycle from cell differentiation in development

Summary: This Spotlight surveys investigations of the dependence of cellular differentiation on the cell cycle in animals. Strict dependence is uncommon. The decoupling of the cell cycle and different...

In the nucleus, many intrinsically disordered proteins (IDPs) form condensates. What IDP sequence features drive this behavior? We developed CondenSeq, a high-throughput approach to measure nuclear condensate formation, and applied it to ~14,000 IDPs to find out! rdcu.be/eq975

Characterizing protein sequence determinants of nuclear condensates by high-throughput pooled imaging with CondenSeq

Nature Methods - CondenSeq is an imaging-based, high-throughput platform for characterizing condensate formation within the nuclear environment, uncovering the protein sequence features that...
