Design of CRISPR components
At the forefront of this innovation is California-based startup Profluent. Using an AI model similar to the one behind ChatGPT, the company developed OpenCRISPR-1, a gene editor that dramatically improves the accuracy of targeted gene editing. The system reduces off-target effects by approximately 95% compared to traditional CRISPR methods, highlighting the potential for AI to revolutionize gene editing. SingularityHub.
Prediction of on- and off-target activity
Deep learning models such as TIGER (Targeted Inhibition of Gene Expression by Guide RNA Design) are improving the accuracy of CRISPR-Cas13d guide RNAs. Researchers at Columbia Engineering and the New York Genome Center developed TIGER to predict both on-target and off-target activity. This advancement is critical for targeting therapies against diseases caused by gene dosage imbalances, such as Down syndrome and certain cancers. SciTechDaily.
Improving the efficiency of gene editing
AI is also improving the efficiency of CRISPR by creating optimized guide RNAs (gRNAs). Machine learning models analyze extensive datasets from CRISPR screens and predict which gRNAs will be most effective for specific gene targets. This capability not only increases the precision of gene editing, but also accelerates the development of new therapeutics (ScienceDaily).
Expanding the power of CRISPR
AI is expanding the CRISPR toolkit by discovering new Cas proteins with diverse functions. By generating millions of potential Cas protein sequences, researchers have identified proteins that can effectively target DNA or RNA. These new proteins are being used in a variety of applications, from gene editing to diagnostics to antiviral therapeutics. SingularityHub.
Future outlook
The convergence of AI and CRISPR technology is expected to revolutionize genetic research and therapeutic development. As AI continues to evolve, we can expect more sophisticated and more precise gene editing tools, paving the way for breakthroughs in treating genetic diseases and advances in personalized medicine. These advances highlight the powerful synergy between AI and genetic engineering, and herald a new era in biotechnology where precision and customization in gene editing will become the norm.
