Nature Study Retools Human AGO2 Into ALTER, A C-to-U RNA Editor That Tops Cas13 Comparators In HEK293T Cells

The work, published in Nature Biotechnology, describes AGO-led targeted editing of RNA, or ALTER, which fuses human AGO2 to a C-to-U deaminase and uses guide RNAs designed to favor binding over cleavage. The study positions a human-protein scaffold as a possible way to reduce some translation risks associated with nonhuman RNA editors, including delivery and immunogenicity concerns.
