The Zhiwei Huang lab report on a hypercompact IS607 TnpB protein that naturally co-occurs with the conserved RAGATH-18 RNA, thereby identifying a new family of compact RNA-guided DNA endonucleases. Such an IS607 TnpB-based approach for programmable genome editing in both Escherichia coli and human cells, combined with its structural and target-adjacent motif divergence from earlier reported IS200/IS605 TnpB systems, highlights the diversity of the non-Cas genome editor toolbox.
