De novo Protein Designer DNA Origami wizzard I like lifting rocks PhD student @TU_Muenchen

Joined June 2013
Finally, out in @ScienceMagazine today, our work on de novo protein design. Together with @HattoriLab , @sokrypton & @hendrik_dietz we showed how we can drastically improve AF2 based hallucination, surpassing, or reaching SOTA diffusion models.

I became aware of the true Munich-Augsburg rivalry today🚀
Dear rocket colleagues from the neighboring city, we send our very best wishes for your launch campaign of Spectrum! 🚀. We know very well what an incredible challenge it is to develop, build, test and finally launch a rocket. And how much passion, perseverance, nerves of steel.

I somebody up to date about the legal aspect of redesigning existing antibodies etc? Just wondering how dis-similar a sequence needs to be, to be able to be used again? .Nevertheless, the results are 🔥🚀.
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

For round three we need a @Foldit puzzle. Would be hilarious if some random person outperforms all the ML methods 😅.
Our 2nd protein design competition saw designers racing to optimize their protein scores until the last minute. Want to know which were the most successful ML methods? Was RFdiffusion more popular than Bindcraft? . Check out our analysis of the submissions in our new blog post

This is awesome! Generate a binder, insert it onto a CAR, kill cancer cells reliably! Stunning results!.
Cancer escapes immunotherapies by mutating its surface. This means even groundbreaking #CARTCell therapies fail too often because of cancer resistance. But what if we could use #GenerativeAI to design CAR-T with de novo binders faster and smarter, targeting even resistant tumors?

If you have questions, suggestions etc, please let us know! We are still trying to make things better, get more data, controls and expand usefulness and obviously – if you wanna look at one if this letters in cryo: we are more than happy to help you out! :).

This was a super fun collaboration with @sokrypton & @hendrik_dietz . Thanks to @DominikSchiwie0 for all the help with designing shapes and twitterless Lara Fuß for all the help with colony picking.

Now, where is the limit? We went even further, testing 2000 AA designs in silico, but up to this point we haven’t succeeded in finding a designable sequence for our protein pretzel :D

We tested just one sequence, which worked out of the box, and we got clean samples right after the Nickle-NTA purification. TEM analysis also showed that the designed protein seems to agree very well with the designed shape.

We then wanted to push the size limits even further. When designing a 1500 AA triangle shaped protein we noticed that neither ESMFold, nor AF2 with IG & AA could predict the sequences confidently, so we went with AF3, which did a better job.

I was honestly surprised how well this worked. The TEM micrographs are so cool :D Just a bunch of tiny shapes
