With David and the Baker Lab in the spotlight today, I wanted to share some insights into the @UWproteindesign and how it operates, a glimpse behind the curtain. I had planned to write this post-graduation, but now seems as good a time as any. (Got twitter blue free trial so this…

BREAKING NEWS The Royal Swedish Academy of Sciences has decided to award the 2024 #NobelPrize in Chemistry with one half to David Baker “for computational protein design” and the other half jointly to Demis Hassabis and John M. Jumper “for protein structure prediction.”

Our latest from @TheCrick, now on @biorxivpreprint: biorxiv.org/content/10.110… Michael Herger (@HergerMichael) and Christina Kajba jointly led development of a new prime editing platform for testing large numbers of human genetic variants.

Our work led by @megan_buckley01 on Saturation Genome Editing of VHL is now out in @NatureGenet: nature.com/articles/s4158… Many new experiments and analyses to quickly highlight… (1/n)

Weekend project: Comparing ESM3 from @EvoscaleAI to ESM2 and inv_cov. The ultimate test of a protein language models is how well the pairwise dependencies it learns correlate to structure. (1/8)

We have trained ESM3 and we're excited to introduce EvolutionaryScale. ESM3 is a generative language model for programming biology. In experiments, we found ESM3 can simulate 500M years of evolution to generate new fluorescent proteins. Read more: evolutionaryscale.ai/blog/esm3-rele…

In the latest edition of "Huh, I didn't expect that to work", our latest paper shows that LLMs can outperform existing methods for identifying causal genes in genome-wide association studies. 🧵 medrxiv.org/content/10.110…


Great opportunity, the job post is still open!

The protein design & informatics group at @GSK is looking to hire a computational biologist in the UK and/or switzerland jobs.gsk.com/en-us/jobs/384…


Aleix Lafita Reposted

The end goal is not to replace variant effect predictors (like AlphaMissense, EMS or EVE) but to provide a predicted mechanism of effect to overlay on these predictors. For example, cancer hotspot mutations tend to have a higher fraction of variants at interfaces than clinvar.

Great preprint and resource from @OpenTargets with contributions from our team at GSK!

New preprint: sequence-based models are very good at predicting human protein missense variants with an impact on function. Here we use AlphaFold2 models to infer mechanisms of effect of deleterious variants (stability, pockets and protein interfaces) biorxiv.org/content/10.110…

Introducing Genie 2, our latest protein design model! Genie 2 sets a new state of the art on key design metrics and supports motif scaffolding, including that of multiple motifs with undefined geometric relationships, a feature new to protein diffusion models. (1/5)


Aleix Lafita Reposted

To help scientists explore whether a genetic variant is likely pathogenic, and which regions of proteins are functionally important, we've integrated AlphaMissense data by @GoogleDeepMind into @ensembl, @uniprot & the AlphaFold database. ebi.ac.uk/about/news/tec…
