CRISPR-TAPE: protein-centric CRISPR guide design for targeted proteome engineering.

Area of Science:

• Molecular Biology
• Protein Engineering
• Bioinformatics

Background:

• CRISPR-based protein engineering is limited by gene-centric guide RNA (gRNA) design tools.
• Existing tools require significant post hoc curation for effective protein modification.

Purpose of the Study:

• To develop a protein-centric algorithm for guide RNA (gRNA) design.
• To enable precise targeting of specific amino acid residues or types within proteins.
• To enhance the efficiency and reduce the complexity of protein engineering using CRISPR technology.

Main Methods:

• Developed CRISPR-TAPE, a novel algorithm for protein-centric gRNA design.
• Algorithm allows targeting of specific amino acid residues or types.
• Outputs are customizable for homology-directed repair efficacy.

Main Results:

• CRISPR-TAPE facilitates direct targeting of protein residues, bypassing gene-centric limitations.
• Customizable gRNA outputs optimize homology-directed repair for engineering.
• Reduced post hoc curation, simplified outputs, and decreased computational time.

Conclusions:

• CRISPR-TAPE offers a powerful protein-centric approach for rational protein engineering.
• The algorithm streamlines the design process, improving efficiency and accessibility.
• Enables precise and effective protein modification through targeted gRNA design.
