Maintenance of nucleosome organization through replication and transcription counteracts aberrant coalescence of active chromatin
Frater et al. show an essential role of mammalian FACT in coordinating replisome and RNA polymerase progression through chromatin with histone recycling to maintain histone modifications. They further demonstrate that losing nucleosome organization can dynamically regulate chromatin compartmentalization.

RNA-seq tells us how much RNA is present in the cell. But to understand gene regulation, we need to easily measure the synthesis and decay rates driving this abundance. We introduce AIR-seq: analog intrinsic recoding sequencing. (1/6) www.biorxiv.org/content/10.6...

Dear Colleagues, Delighted to share that our first lab paper is now published in Nature.!!! 😊😊😊 We identify a previously concealed “safety limit” in DNA replication program: cells intrinsically rate-limit PCNA via PAF15, shaping strand-specific and global replication dynamics. 👉 rdcu.be/e1bBt
