Improved protein binder design using beta-pairing targeted RFdiffusion
🚀 New preprint from David Baker!🚀
• A breakthrough in protein binder design: this study uses RFdiffusion conditioned to generate binders that form precise beta-strand pairings with polar protein targets, yielding binders with superior affinity and specificity.
• The approach focuses on polar regions of target proteins, especially edge beta-strands, addressing the challenge of complementing hydrogen bond donors and acceptors that are otherwise exposed to water.
• Designed binders achieved affinities ranging from 76 pM to mid-nanomolar, targeting therapeutically relevant proteins like KIT, PDGFRɑ, and ALK-2, with no significant off-target binding.
• A co-crystal structure of a binder in complex with the KIT receptor confirms the computational accuracy of this new design method, showcasing near-perfect matching of the design model and real-world interactions.
• This beta-strand focused method not only enhances the range of RFdiffusion’s capabilities but also expands the potential for developing new therapeutic binders targeting polar protein surfaces, such as those in cancer-related pathways.
• The new design approach surpasses traditional methods, particularly in targeting polar regions and edge beta-strands in proteins like ALK-2, ALK-3, and PDGFRɑ, where previous techniques failed to generate effective binders.
• The study demonstrates that beta-strand pairing conditioned designs have higher thermal stability and are more specific in binding compared to earlier models, making them valuable for therapeutic applications like receptor targeting and drug delivery.

Given ISOLDE is a model-fitting tool, it was about time I gave it a way to, you know, actually validate the fit of a model to a map. As such, in consultation with Greg Pintille and Tom Goddard I've implemented the Q-Score algorithm (https://t.co/tbacFT1AOd) in ChimeraX. (1/2)
