Our laboratory seeks to understand how chromosome structure relates to genome functions Tweets by Elphege

First preprint from the lab šØ. How can enhancers regulate target promoters across vast genomic distances, and what is the role of cohesin loop extrusion in the process?. (1).
biorxiv.org
Enhancers are critical genetic elements controlling transcription from promoters, but the mechanisms by which they convey regulatory information across large genomic distances remain elusive. Here,...

CTCF, just like any transcription factor, binds its target sites on and off. Turns out considering this dynamic is essential to explain chromosome folding patterns from Hi-C and microscopy, and how they rearrange upon tampering with cohesin. What an exciting manuscript! š.
Happy to share work with Hadi, Yao & @Maxime_Tortora characterizing the impact of dynamic CTCF barriers for cohesin loop extrusion.
