Engineered human Argonaute 2 is presented as a programmable RNA-targeting platform; this article explains the approach, guide design, and platform potential.
Key Takeaways
- Human Argonaute 2 (AGO2) can be repurposed as a programmable RNA-targeting platform when fused to a C-to-U deaminase.
- ALTER uses redesigned guide RNAs that remodel local target RNA structure to enable selective C-to-U editing with reduced nuclease activity.
- In HEK293T cells, ALTER produced higher on-target C-to-U editing and comparable or lower transcriptome-wide off-target editing than Cas13-based editors.
