Researchers Leverage AlphaFold to Engineer Safer CRISPR Cas9 Variants

Key Points

• AlphaFold was used to model Cas9 interactions with DNA and guide RNA.
• Simplified inputs (DNA, RNA, Cas9) yielded accurate structural predictions.
• Off‑target sites often cause amino‑acid contact shifts without major shape changes.
• Contact probability data enabled a comparative analysis dubbed ContactSeek.
• ContactSeek identified clusters of flexible residues for targeted redesign.
• Engineered Cas9 variants showed reduced off‑target binding in early tests.
