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:

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... https://www.biorxiv.org/content/10.1101/2025.03.15.641049v1
