Our study is out in @NatureComms! Beyond genome folding, cohesin helps recruit RNA polymerase II and restrains its pause release. In cultured human cells, we reveal how this supports productive transcription. 1/4

A model explains the modest RNA changes: reduced Pol II recruitment and faster pause release can offset each other. But TNF-alpha-induced gene activation was impaired after cohesin loss, revealing a role masked at steady state. Fig. 7c,e

Why does pausing matter? After cohesin removal, RNA polymerase II associated with fewer elongation factors, and we found evidence consistent with premature termination. Pausing appears to allow time to prepare for sustained elongation. Fig. 2a-e
