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
PAF15–PCNA exhaustion governs the strand-specific control of DNA replication
Nature - PCNA–PAF15 has a key role in determining replisome dynamics during genome replication and protecting against genome instability.
