AI 'Raygun' can shrink and supersize proteins – enabling easy editing
Researchers have developed an AI tool called Raygun that can shrink or supersize proteins without disrupting their shape or function. This tool uses a mathematical approach to modify existing proteins, allowing for easy editing and potential applications in biotechnology. The study, published in Nature, demonstrates the potential of Raygun to create smaller or larger versions of existing proteins, which could be useful in various fields.
- ▪The AI tool Raygun can modify existing proteins by adding, deleting, or substituting protein subunits.
- ▪Raygun uses a mathematical approach to create a standardized version of the protein, allowing it to generate proteins at various sizes without compromising their structural integrity.
- ▪The tool has the potential to enable easy editing of proteins, which could be useful in biotechnology applications.
