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.

If you want to learn how targeting cohesin to defined loci in the genome affects the local chromatin environment and transcription, look no further!

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. 🧵👇

-PDS5 facilitates NIPBL dissociation from cohesin by invading NIPBL binding site
-PDS5 strengthns CTCF boundaries by limiting NIPBL-cohesin life
-PDS5 lowers avg extrusion speed/depletion ups processivity
-Compartmentalization governed by competition of extrusion &polymer relaxation dynamics

Hi-C in cells depleted of PDS5 & now partially of NIPBL recover some of CTCF boundaries (+ also compartments)

PDS5+NIPBL could colocalize on cohesin leading to NIPBL unbinding! Loops often released but sometimes shrunk & NIPBL returned.
So PDS5 slows loop growth + speeds NIPBL unbinding by facilitated dissociation!
