Ah, the wonders of modern education: 🌟 a 3D animation showing DNA replication that’s perfect for middle schoolers who can’t get enough of Ötzi 🧊 and CSHL’s endless list of field trips. Because nothing says cutting-edge science like a glorified screensaver and a list of activities longer than the human genome itself. 🧬🎉

The structure of the tetrameric GINS complex from S. solfataricus reveals a core structure highly similar to the previously determined GINS core structures of other eukaryotes and archaea #DNAReplication #GINS #MinichromosomeMaintenance https://doi.org/10.1107/S2053230X25003085
Structure of the Saccharolobus solfataricus GINS tetramer

Archaeal organisms possess Cdc45 and GINS homologs that are likely to serve similar functional roles, but their structural interactions with the MCM helicase and hence their mechanism of MCM activation are not as well understood as for their eukaryotic counterparts. We present the crystal structure of the S. solfataricus GINS tetrameric complex and illustrate that a subdomain would need to move to accommodate known archaeal GINS-complex interactions and to generate an S. solfataricus CMG complex analogous to that of eukaryotes.

The crystal structure of proliferating cell nuclear antigen 1 from Aeropyrum pernix revealed that it does not form a trimeric ring, unlike those from other domains of life #ProliferatingCellNuclearAntigens #DNAReplication #AeropyrumPernix https://doi.org/10.1107/S2053230X24009518
X-ray crystal structure of proliferating cell nuclear antigen 1 from Aeropyrum pernix

The crystal structure of proliferating cell nuclear antigen 1 from the thermophilic archaeon A. pernix was determined at 2.00 Å resolution. This crystal structure revealed unique features in the N-terminus, including a PIP-box-like sequence, suggesting potential interactions with other proliferating cell nuclear antigens.
