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.

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.

New work published in @natcomms.nature.com has shone light on how a protein called geminin ensures DNA is only replicated once before cells divide, helping cells to maintain the integrity and accuracy of their DNA.

This work was a collaboration between the LMS and @imperialchemistry.bsky.social

It is not always safe to repair DNA Damage. Sometimes, cells "just bypass it".

During DNA replication, repair of lesions on DNA can be dangerous. Cells instead "tolerate" DNA damage and focus on finishing replication.

Single-molecule analysis reveals the mechanism of chromatin ubiquitylation by variant PRC1 complexes Single-molecule experiments show that active conformation formation controls chromatin ubiquitylation kinetics by variant PRC1.

Our new study of chromatin ubiquitylation by variant PRC1 on the single-molecule scale: We visualize directly how vPRC1 ubiquitylates neighboring nucleosomes during a single binding event, showing a potential mechanism how H2Aub domains are established.
