Genetic diseases caused by point mutations or small insertions/deletions pose a significant challenge to current therapeutic approaches. Base editing, a precise and targeted genome editing tool, has shown great promise in treating these conditions. However, the delivery of base editing enzymes into cells remains a major hurdle for clinical translation. The efficiency of base editing can be significantly reduced by the need for high concentrations of enzyme, which may not be feasible with existing delivery methods. In this study, Mu and colleagues present a novel approach to overcome this limitation using programmable coiled-coil assembly. This method enables the creation of highly efficient split base editors that can be easily assembled in vitro or in vivo. The authors demonstrate the efficacy of their approach by showing its in vivo functionality in a mouse model. By harnessing the power of molecular velcro, these researchers have opened up new avenues for precision genome repair and may pave the way for more effective treatments of genetic diseases. However, it is essential to note that this research is currently limited to laboratory use only (RUO) and has not been approved for clinical use. As such, any attempts to replicate or build upon these findings should be made in a controlled laboratory setting with proper safety protocols in place.
