RNA polymerase II coordinates histone deacetylation at active promoters
Transcription initiation limits histone acetylation and H2AZ incorporation at promoters.

Unpause! I'm super happy to now be able to share the published version of our paper at Science Advances showing that:
1) active histone mods occur independently of transcription
2) transcription coordinates histone deacetylation at active promoters

Some context since this is getting reposted a bunch today: "unpause" was not a reference to RNAP2 pausing, but rather the end of the imposed communications pause that started in early Jan and ended a couple weeks after this was published
