We were thrilled to synthesize the DNA needed for the competition and extend our congratulations to the teams and organizers on such a fantastic event!

Prediction of eukaryotic cellular complexity in Asgard archaea using structural modelling - Nature Microbiology A structural catalogue of the Asgard archaeal pangenome reveals hundreds of eukaryotic-like proteins that suggest a higher degree of cellular complexity in the archaeal ancestor of eukaryotes.

Fun new paper out today - a collaboration led by @stephkoe.bsky.social and @ettema.bsky.social found lots of new Euk-like proteins in Asgard Archaea

Amazing work from Clay @kosonocky.bsky.social, Alex Abel and LEAH labs, and all the collaborators and participants in the Bits2Binders AI CAR-T therapy protein design competition. The results are in!

The Bits to Binders competition was created to evaluate AI-driven methods on their ability to create proteins that function in a realistic, cellular context; in this case CD20-targeting binders as Chimeric Antigen Receptor (CAR) binding domains that elicit a CAR-T response

In summary, we find that most of the failures seem to have been caused by impaired translation and protein expression. We believe that optimizing sequence-level properties for expression is just as important as the structure-centric task of binding

If we removed seqs with:
β‰₯60% GC and <1.9 DNA entropy
β‰₯45 AA repeats (DNA)
β‰₯8 EE repeats
β‰₯30% K+E alpha helix

We would remove 4,600 designs, increase recovery from 57% to 81%, and CD20-specific proliferation from 5.9% to 7.6% while removing 2/3 non-functional top 10 designs

In summary, we have confirmed that at least three teams were able to create broadly functioning CD20-specific immunotherapies using the AI-driven tools of their choice. We gave our awards to these teams and others based on the functional assays released last September.

Team hits rates ranged from 0.6% to a staggering 38.4%!

And surprisingly, over half of the designs failed to proliferate in either condition, indicating that the designs interfered with CAR expression.

I'm thrilled to announce that the manuscript for the Bits to Binders protein design competition is out on bioRxiv! Here's a summary of our findings, including some simple criteria that nearly *double* success rates when applied as a filter 🧡

I was sad to learn that my postdoctoral mentor, David Botstein, died yesterday. I started with David as a postdoc in 1998, and he had a profound effect on both my life and scientific career. He was a giant in the field of genetics, making seminal contributions in both yeast and human genetics. 1/

Ah, no. What a terrible loss. He was a wonderful scientist who touched so many of our lives.

One of the biggest questions in biology is how complex cells evolved about 2 billion years ago. Here's my new story on how scientists are solving the mystery of eukaryotes like us. Gift link: nyti.ms/4qMbo22

We are hiring a postdoc! The group has a funded opening to join our amazing team on the NCI's Frederick, MD campus.

This is an opportunity to train in cutting-edge chemical & RNA biology methods with a supportive, tight-knit group.

A line graph showing the number of new and competitive renewal awards for fiscal years 2021-2026. The curve for fiscal year 2026 is essentially zero on this scale with 121 awards compared to close to 3000 awards to the same date in earlier years.

These are the curves for new and competitive renewal grants.

The number of new awards is increasing slightly, but only slightly.

17 out of 25 institutes and centers with funding authority have now made awards.

It has been two weeks since the unexpected death of Peer Bork, and all of us in his research group are deeply missing him. His scientific vision brought us together as a team, and we are immensely grateful for the time we spent together. 🧡
