The Skok Lab is recruiting an experienced computational scientist to lead single-molecule epigenomic and 3D genome analysis. We integrate long-read sequencing with Hi-C/Hi-ChIP, scmulti-omics, and machine-learning to explore chromatin topology, and gene regulation.

New preprint with @gfudenberg.bsky.social

We find the rate of cohesin loop extrusion in cells is set by NIPBL dosage and tunes many aspects of chromosome folding.

This provides a molecular basis for NIPBL haploinsufficiency in humans. 🧵👇

NIPBL dosage shapes genome folding by tuning the rate of cohesin loop extrusion
Cohesin loop extrusion is a major driver of chromosome folding, but how its dynamics are controlled to shape the genome remains elusive. Here we disentangle the contributions of the cohesin cofactors ...

I’m excited to highlight our latest paper, just published in Cell 🎉

We report the existence of a previously uncharacterized signaling pathway that is responsible for activating cell death upon loss of gene expression.

We found a new asymmetry in the large-scale chromosome structure: sister chromatids are systematically shifted by hundreds of kb in the 5′→3′ direction of their inherited strands! The work was led by Flavia Corsi, in close collaboration with the Daniel Gerlich lab.

Excited to share our latest work on how cells fold their genomes, and build mitotic chromosomes! Out in Science today!

Lots of interesting results and proposals for those interested in loop extrusion, and chromosomes!

With @golobor.bsky.social, Leonid Mirny, Bill Earnshaw labs.

See thread below:
Earnshaw, Goloborodko, Dekker & Mirny labs are excited to present our latest work, "Rules of engagement for condensins and cohesins guide mitotic chromosome formation" - now accepted!!

Nice work! Go TADs!
In this study, Huang et al. demonstrate how a single enhancer independently controls the expression of two distal and functionally unrelated genes.

Here is the peer-reviewed version of our study showing how some TAD borders are essential for gene regulation and development.

Loss of a single CTCF motif is sufficient to cause embryonic lethality.
