Now online! Structural basis of a SWI/SNF-associated transcription pre-initiation complex

Structural basis of a SWI/SNF-associated transcription pre-initiation complex
Cryo-EM and genetic analyses reveal that the SWI/SNF chromatin remodeler is an integral component of the transcription pre-initiation complex. The structures demonstrate how SWI/SNF facilitates transcription initiation through stabilization of PIC organization and concerted remodeling of the +1 nucleosome.

Is euchromatin really “open”? 🧬 Using super-resolution imaging🔬 our new study @natgenet.nature.com reveals: Euchromatin forms condensed domains in live cells. Cohesin constrains them and prevents domain mixing for proper transcriptional insulation🚧 🔗 www.nature.com/articles/s41... (1/2)

New #RibackLab preprint! The nucleolus's biophysical properties aren't fixed—they're tuned to energy availability. Under nutrient limitation, nucleoli hibernate: stronger interactions, slower rRNA transport, rapid reversal upon refeeding. Led by incredible postdoc @evdokiiap.bsky.social 🧵👇

We know little about proteins required for long-range compartment 3D interactions, but this @kyleeagen.bsky.social lab preprint shows that NSD3 can make Mb-scale long-range compartment-like interactions: www.biorxiv.org/content/10.6...

Excited to see James' Genome-wide Absolute Quantification of Looping paper out in @natsmb.nature.com : www.nature.com/articles/s41... This has been in collaboration with @lucagiorgetti.bsky.social @leonidmirny.bsky.social @zechnerlab.bsky.social labs. Brief thread below on some key updates

Happy to share that my postdoc work with @jobdekker.bsky.social is out! rdcu.be/eWHD2 We characterize interphase chromatin folding programs with distinct modes of mitotic inheritance and identify the chromosome-intrinsic capacity to form a microcompartment of active CREs during mitotic exit.

Inheriting chromosome conformation - Nature Cell Biology
Chromosomes unfold and refold each time cells divide. A study by Schooley et al. demonstrates that chromosome-intrinsic and cytoplasmic factors uniquely contribute to interphase chromosome structure, with new possibilities for how gene expression programs are passed from mother cells to daughter cells.

Exciting new paper out! @allanaschooley.bsky.social and Sergey Venev led this project that let to the discovery of two chromosome folding programs: one inherited via mitotic chromosomes and one mitotic inherited through the cytoplasm! www.nature.com/articles/s41...

In lab’s #FIRSTPREPRINT, we present methods to measure nanometer-scale organization around & between specific proteins in condensates in live cells. We uncover unexpected heterogeneity for a liquid-like phase with local meshwork spanning 10-50nm, stemming from ribosome biogenesis in the nucleolus.
