Overview
- ContactSeek, which was published in Nature on July 22, 2026, uses AlphaFold3 contact predictions to find protein sites that make unwanted DNA contacts and proposes residue swaps to reduce those contacts.
- The team engineered an adenine base editor with just two mutations that significantly improved precision while retaining or improving intended on-target activity compared with established high-fidelity editors.
- ContactSeek proved modular when adapted to a different editor family, producing redesigned LbCas12a-based cytosine base editors that also showed improved selectivity.
- All code and datasets for ContactSeek v1.0.0 were released on Zenodo and GitHub, which speeds replication and adoption but raises immediate calls for broad specificity and safety testing before clinical use.
- The work builds on recent AI protein-design advances and could compress development timelines for safer gene therapies, yet regulators, clinicians, and researchers say systematic preclinical profiling and regulatory review are still required before human applications.
