Dissecting protein function in vivo: Engineering allelic series in mice using CRISPR-Cas9 technology

Area of Science:

• Genetics
• Molecular Biology
• Biotechnology

Background:

• Allelic series are crucial for studying gene function and protein structure.
• Traditional methods for generating allelic series in mice are time-consuming and complex.
• CRISPR-Cas9 technology offers a precise and efficient alternative for creating genetic mutations.

Purpose of the Study:

• To describe step-by-step procedures for generating diverse mutations using CRISPR-Cas9.
• To demonstrate the utility of CRISPR-Cas9 for creating allelic series in mouse models.
• To dissect protein function in vivo using precisely engineered mutations.

Main Methods:

• Utilized CRISPR-Cas9 gene editing technology for targeted mutagenesis in mice.
• Developed protocols for generating missense mutations.
• Established methods for creating large in-frame deletions and insertions of genetic material.

Main Results:

• Successfully generated three distinct types of mutations (missense, deletion, insertion) using CRISPR-Cas9.
• Demonstrated the feasibility of creating allelic series for functional gene analysis.
• Used SCY1-like 1 (Scyl1) as a model gene to validate the procedures.

Conclusions:

• CRISPR-Cas9 technology provides a powerful and cost-effective platform for generating allelic series.
• These methods facilitate the dissection of gene and protein function in vivo.
• The described protocols offer valuable tools for genetic research and model organism development.
