Nature: AI Tool 'Raygun' Can Shrink and Supersize Proteins on Demand
Dr_Singularity · x · 2026-07-30
Nature reported on an AI tool named Raygun that can 'miniaturize' or 'supersize' natural proteins without disrupting their original folding shape or function.
- Technical Breakthrough: While previous models mostly generated entirely new proteins from scratch, Raygun modifies existing ones using natural evolution-inspired steps: adding, deleting, or substituting individual amino acid subunits.
- Applications: This technology could enable the creation of more efficient enzymes, compact therapeutic proteins that fit into hard-to-reach targets, and improved biologic drugs.
- Expert Opinion: Fajie Yuan, a computational biologist at Westlake University (not involved in the study), called it a 'meaningful and creative' first step toward editing existing proteins, perfectly addressing the practical need for adaptable versions of known proteins.
