Inspired by @owl_posting's recent Socratic dialogues about the utility of DNA models, I wrote a Gödel, Escher, Bach-style dialogue about different approaches to protein–ligand binding-affinity prediction. (The weirdest writing I've shared publicly?) https://t.co/n7nHOPiaf1

With the start of my first batch as a visiting partner at @ycombinator, this felt like a good time to write my founder story about our journey at @reverielabs. It's a bit of a long one. https://t.co/KWyMxPDdXO

In new work led by @aditimerch with @samuelhking, we prompt engineer Evo to perform function-guided protein design with high experimental success rates, including designs that go beyond natural sequences. We also release SynGenome, the first AI-generated genomics database. 🧵 1/N

PROTEIN DESIGN COMPETITION ROUND 2 The long awaited results are here -- and they don’t disappoint! 📈 We doubled the number of proteins we tested in our lab from 200 to 400! 🧬 Out of those 400 proteins, 378 expressed (95% expression rate!) 🚀 Out of those 378 expressed

Introducing ESM Cambrian. Unsupervised learning can invert biology at scale to reveal the hidden structure of the natural world. We’ve scaled up compute and data to train a new generation of protein language models. ESM C defines a new state of the art for protein

Can a single small molecule rescue the stability of nearly all mutations in a protein? Our new preprint by @taylor_mighell + thread https://t.co/pYw0RHCpKB

Reduced protein stability is the most frequent mechanism by which rare missense variants cause disease. A promising therapeutic avenue for treating destabilizing variants is pharmacological chapero...
A major challenge in treating rare genetic diseases is the huge number of causal variants in different individuals. This led to assumptions that any given treatment would be suitable only for a small fraction of patients

Remember Golden Gate Claude? @etowah0 and I have been working on applying the same mechanistic interpretability techniques to protein language models. We found lots of features and they’re... pretty weird? 🧵

Have you ever wanted to design protein binders with ease? Today we present 𝑩𝒊𝒏𝒅𝑪𝒓𝒂𝒇𝒕, a user-friendly and open-source pipeline that allows to anyone to create protein binders de novo with high experimental success rates. @befcorreia @sokrypton

The Adaptyv results are out! Very few designs actually bound. The Design Process text is interesting, e.g., looks like the highest scoring was due to a "new user-friendly binder design pipeline based on AlphaFold2 backpropagation" from @MartinPacesa
🧬 Protein Design Competition Update 🧬 Experimental characterization for all protein designs has been completed! We are still processing the last experiment runs and will be releasing the results on Friday Sep 20 at 6 PM CET - 2 PM EST - 9 AM PDT https://t.co/QvTEyKd7ak

1/ I did my own little hackathon last weekend designing EGFR binders for @adaptyvbio's protein design competition. I was really excited to see that my submissions took the top 10 spots in the virtual scoring phase! I got some DMs asking about my process so here's a thread:

De novo protein design is great, but nature has millions of proteins- why not repurpose them? Introducing Raygun, a new approach to protein design. It allows you to miniaturize, magnify or modify any protein. We synthesized miniaturized variants of eGFP and mCherry! 1/

I've noticed that biotech cos built around a computational discovery platform have a different philosophy on company building and how to use software to gain sustainable advantage vs. 'traditional' biotech or pharma. I reflect on this in a new blog post:

The “known protein universe” is big: hundreds of millions of sequences from thousands of species. @ArcadiaScience we wondered, how well does it reflect the “actual” protein universe? 🧵[1/15] https://t.co/p4el3tmkx2
