An in-press version of our latest paper in @natcomms.nature.com on phospho-activated protein-protein interactions with ssDNA-binding protein RPA during BIR. If your favorite pathway involves RPA, this may be for you! Thanks to the lab, collaborators & @ukri.org! www.nature.com/articles/s41...
Nature Communications banner with title of latest paper from the Yates, Oliver, and Rass groups at the Genome Damage and Stability Centre, University of Sussex: "Break-induced replication is enhanced by a phospho-activated RPA-binding module in Pol32".

Cryo–electron microscopy structure of the budding yeast telomerase holoenzyme
Telomerase is a reverse transcriptase that synthesizes telomeric repeats at chromosome ends, safeguarding genome integrity. We present the cryo–electron microscopy structure of the budding yeast telom...

🚨 Our new paper is out! 🙌 Bioorthogonal reactions often create bulky, non-native linkages-great for labeling, but not ideal for installing natural PTMs. We combine GCE with a chemoselective amide-bond forming reaction to install site-specific acylation PTMs. www.cell.com/chem/fulltex... 1/4

Thrilled to share that the final piece of my PhD work is now on bioRxiv! biorxiv.org/content/10.1... With support from @nvidia and the @NSF, we used AlphaFold to screen 1.6M+ protein pairs, revealing thousands of potential novel PPIs. All data can be viewed at predictomes.org/hp

Protein-protein interactions (PPIs) drive virtually all biological processes, yet most PPIs have not been identified and even more remain structurally unresolved. We developed a two-step computational...

Thrilled to share our lab's first preprint, led by an exceptional PhD student Gita Chhetri and with the support of wonderful collaborators, we find that replisome function is rate-limited by strand-specific PCNA dynamics. Hope you will enjoy reading. www.biorxiv.org/content/10.1... Brief teaser:

Review: Hyrien et al. discuss the nature of the initiation sites of DNA replication, amalgamating findings from various advanced DNA replication mapping techniques in order to build a more cohesive model of DNA replication initiation. Learn more here: ➡️ tinyurl.com/gd352227

Why does yeast replication require two alternative clamp loaders? Joe Yeeles and coworkers show that RFC can only load PCNA on lagging strands, while leading strand polymerases necessitate the involvement of CMG-interaction Ctf18-RFC www.embopress.org/doi/full/10....

What do you pay for 500uCi of γ-32P-ATP at your institutions? We were just quoted $1600 for something we paid $900 till a few weeks ago.
