CRISPR-Cas is used broadly in research and medicine to edit, insert, delete or regulate genes in organisms. TnpB is an ancestor of this well-known “gene scissors” but is much smaller and thus easier to transport into cells.

Using protein engineering and AI algorithms, University of Zurich researchers have now enhanced TnpB capabilities to make DNA editing more efficient and versatile, paving the way for treating a genetic defect for high cholesterol in the future. The work has been published in Nature Methods.

CRISPR-Cas systems, which consist of protein and RNA components, we...

Kobe University researchers have succeeded in developing ‘Target-AID’, a genome editing technique that does not cleave the DNA. The technique offers, through high-level editing operation, a method to address the existing issues of genome editing. It is expected that the technique will be applied to gene therapy in the future in addition to providing a powerful tool for breeding useful organisms and conducting disease and drug-discovery research.

Genome editing – which can directly manipulate the genome information of various organisms without leaving an artificial strand – has seen rapid progress in recent years and it is gradually becoming a revolutionary tool in fields ranging from life sciences to advanced medical research...
