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.
Run AlphaFold2 locally in your browser via WebGPU, no installation needed, it's just a static webpage using your own GPU or CPU. Short proteins run in seconds. Larger ones are still slow: a 291-aa protein takes ~7 minutes on my M4 Pro. ❗It's just a PoC. 🌐 martin-steinegger.github.io/alphafold2-w...

Microbial GAIN domains undergo autoproteolysis and enable release of diverse cell-surface-associated proteins
Brogan and Rudner report the identification of a microbial autoproteolytic domain that is structurally homologous to the GAIN domain of eukaryotic adhesion GPCRs. Rather than participating in transmem...

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.
🧬 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.

Five years ago, the #AlphaFold Database, a collaboration with Google DeepMind, made predicted protein structures free for everyone to use. Today, the database contains over 260 million structure predictions and is used by more than 3.5 million researchers in 190 countries around the world.

A metabolic atlas of mouse aging
Pilley et al. describe how metabolite levels change in 12 organs from male and female mice across five ages, spanning adolescence to old age. They reveal that organs show distinct age- and sex-specific changes in metabolism. They also develop metabolic clocks that predict putative metabolic drivers of aging, including hydroxyproline.

If you use Boltz1/2, BioEmu, Chai1, or other MSA-dependent models, you’re likely using our ColabFold server. Please be considerate! Avoid large submissions across many IPs instead generate the MSA locally. Our server is an old-timer from 2014 and can’t handle that load.

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".
