AlphaFold Database is expanding into pandemic preparedness. Together with NVIDIA, DeepMind, EBI et al. we exhaustively predicted ~1.7 million homo- & heterodimers across 2,812 viral proteomes, resulting in 8,028 high-confidence predictions. 📄 research.nvidia.com/labs/dbr/ass... 🌐 alphafold.ebi.ac.uk

AlphaFold2-WebGPU now supports AlphaFold-Multimer. As in ColabFold, simply use : to separate chains in the sequence input. It is also becoming much more stable: I was able to predict a 491-aa protein in ~4 minutes in M4 Pro. Chrome currently performs better than Firefox for WebGPU, unfortunately.

🧬 How is MCM2-7 switched on? Our paper shows DDK phosphorylation exposes Sld3-binding sites on Mcm4/Mcm6. Sld3-Cdc45 then delivers Cdc45 to Mcm2/Mcm5, driving CMG assembly. In summary, our work explains why MCM2-7 phosphorylation is needed to turn on replication. www.nature.com/articles/s41...

Most PDB structures report one set of coordinates. But the experimental data behind them, in both X-ray crystallography and cryo-EM, is produced by an ensemble of structures. How to extract this ensemble data at scale has been a quest in structural biology for 40+ years.

My latest work! We found that the autoproteolytic GAIN domain which mediates force responsive signaling in adhesion GPCRs is not unique to eukaryotes. The microbial counterparts anchor diverse adhesion, enzymatic, and toxin domains to the cell surface, enabling release by likely mechanical stimuli.

Unexpectedly, @jurgjn.bsky.social found that running Alphafold3 predictions for protein interactions can yield ipTM scores that are more predictive of true interactions when run in pools of proteins instead of pairwise predictions. Presumably, this reflects some sort of "competition effect".
