AI-designed C8 protein vector cuts mRNA dose 10,000x vs lipid nanoparticles
bravo_abad · x · 2026-09-05
Generative protein design is stepping outside evolution's search space for RNA delivery. Using RFdiffusion, researchers created synthetic protein assemblies with unusual cyclic and dihedral symmetries, then grafted known biological domains for membrane binding, budding, and RNA capture.
- AI designs the scaffold; biology supplies functions that already work
- The best design, based on a rare C8 planar assembly, needed over 10,000x less mRNA than a lipid nanoparticle for the same expression level in the reported cellular comparison
A striking example of generative AI exploring protein architectures evolution never tried.
