Researchers report a new genome editing approach called smACGmax that is designed to perform simultaneous adenine, cytosine and guanine editing at the same endogenous loci. The study addresses a major limitation in base editing, where generating broad-spectrum mutagenesis across multiple DNA bases in one target region has remained difficult.
According to the report, smACGmax enables efficient multi-base conversions rather than focusing on just one class of nucleotide change. That broader activity could make it easier to create high-diversity mutation patterns within native genomic DNA, an important step for studying how sequence changes alter gene function.
The work is especially relevant for functional screening, where researchers need a wide range of variants to test the effects of different mutations. By expanding the diversity of edits that can be introduced at a single site, the platform may offer a more flexible way to probe biological mechanisms and map functionally important DNA changes.
The study, published by researchers affiliated with institutions in Shanghai, highlights continuing progress in precision genome engineering. If the method performs reliably across more settings, it could become a useful tool for mutation discovery, variant analysis and other applications that depend on large-scale, high-diversity base editing.
