Proteome-wide in silico screening for human protein-protein interactions 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 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

Happy to share new work from my lab by co-authors Peng and Lee-when BRCA1 is absent, RAD51 is busy authors.elsevier.com/sd/article/S...

🔬 New from the Farnung Lab: We established a fully in vitro reconstituted chromatin replication system and report the first cryo-EM snapshots of the human replisome engaging nucleosomes.

PAF15-PCNA assembly exhaustion governs lagging strand replication and replisome integrity Genome replication in eukaryotic cells is surveyed by the S-phase checkpoint, which orchestrates sequential replication origin activation to avoid exhaustion of hitherto poorly defined rate-limiting r...

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.

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

Replication-IDentifier links epigenetic and metabolic pathways to the replication stress response - Nature Communications Cells activate various pathways to counter DNA replication stress. Using Replication-IDentifier (Repli-ID), the authors identified 423 genes, including LGE1 and ROX1, linking epigenetic and metabolic ...

We present Repli-ID, an approach to identify proteins affecting DNA replication. Lge1 and Rox1 are new regulators of this process. Great work by @sophievdhorst.bsky.social, @lleonie.bsky.social and co-authors in collaboration with @andreichabes.bsky.social.

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.

Hello Tatiana, could you please add our group to this list? Thank you for considering!
