The AI Editor Needed a Human Redesign
Structure-guided engineering raised the efficiency and precision of early AI-designed adenine base editors.
Summary
Structure-guided engineering raised the efficiency and precision of early AI-designed adenine base editors.
A Sungkyunkwan University-led team used predicted protein structures to redesign early AI-derived adenine base editors, producing OpenABE 1.1 and 1.2. The researchers report 16- to 36-fold higher activity than the starting AI-designed editors, reduced nearby off-target editing and activity in nuclear and mitochondrial DNA; the work remains preclinical and does not establish a safe human gene therapy.
Why it matters
