#2025ISMPMI 📣 In silico screening of PRR-epitope interactions is now possible!

Here, we developed mamp-ml to predict their immunogenic outcomes without structural context. Let's accelerate engineering plant receptors for robust resistance! 🚀🌱 Small 🧵

100% agree. Especially with how much money is spent a year toward pub fees (10-30K+) that could go to other career opportunities. Plus, I can get high quality reviews from peers without a formal journal system. Sadly as a postdoc, I feel like my hands are tied, but I would love to help the cause.

Many times, we come back to traditional journals in the end because like NIH grants, preprints don't hold the same weight/merit in trainee fellowships, tenure process, etc. It is still a challenge, though I'd like to think that if established groups move away from trad pubs, others will follow.

Sweet! Those look beautiful. I wish sharing pymol/chimeraX scripts were as common as other computational work and languages.

This is quite interesting, especially since myself and others have found the opposite (ROS, no MAPK)! If I were to $$ on it, my guess is the binding interaction in-complex is causing different PTM modifications on the kinase domain, leading to a bimodal signaling cascade. 🤔 Can't wait to read more!

While there's lots of work to be done, mamp-ml is a critical advancement in plant immunology for accelerating receptor-epitope characterization and engineering resistance. Mamp-ml is on Github and we implemented a version on Google Colab for easy use. Please check it out!

Finally, we also tested its ability to predict outcomes for convergently evolved receptors. SCORE, a csp22 receptor found in Citrus and relatives, was recently discovered by @brunongou.bsky.social. We preliminarily found mamp-ml can zero-shot predict immunogenic outcomes!

Compared to other state-of-the-art models such as AlphaFold3, mamp-ml can predict these outcomes with higher confidence, even when a solved structure is not available. We anticipate users can now screen for immunogenic outcomes of receptor-ligand variants before spending time and $$ in the lab.

Mamp-ml harnesses the power of protein language models (ESM-2) to build a classifier model for immunogenic outcomes.

Previously immunogenicity was primarily characterized in the lab but was a expensive bottleneck considering the variation captured computationally!
danimstevens.bsky.social
We then generated a pipeline that combines AlphaFold2 and LRR-Annotation to precisely extract the LRR ectodomain as well as generated features to improve model training. This even includes tracking which residues interface with the ligand!
danimstevens.bsky.social
Mamp-ml was built upon two decades of foundational research. To generate the training data required, I manually pulled receptor and epitope sequences from every paper I could find, small or large. In total, we were able to capture over 1,300+ combinations across 11 receptors and 91 plant species.

Great presentation from @gittacoaker.bsky.social on kinase mediated defense responses and harnessing the power of language models for receptor/ ligand prediction. These LMs will help us in engineering more resilient crops #2025ISMPMI

While I'm not going to be at #2025ISMPMI this year (🥲),
@kseniakrasileva.bsky.social will be there presenting on some of our latest work that was submitted to BioRxiv today. Teaser: Plant immunity + large language models will transform receptor discovery and engineering for disease resistance. 🌱🚀

It was great to catch up with so many people! Super thankful to Grey Monroe for the invite and enjoyed all the engaging questions. Can’t wait to wrap up this project and get it out there! 😁

2025 has been quite a whirlwind. Learned of good funding news, had my first faculty (zoom) interview, will give my first dept. seminar on Monday at Davis all while trying to keep cool with the current news events. 😆😬🫠

To UC Davis folks, if anyone wants to meet up on Monday, feel free to reach out.

This is the one I would suggest! Was one of the first papers read as part of a phylogenetics journal club/class I took several years ago.

Sometimes the smallest things warm the soul ❤️ so thankful to be part of such a great lab group!
