Deskripsi
Cas12i is a genome editing platform with compact size that fits in AAV vector with short 43-mer gRNA, absence of tracrRNA, ability to process pre-crRNA, and high specificity. Here the authors present an unbiased mutational scanning approach to engineer Cas12i, which shows low activity in mammalian cells, and identify single substitutions that significantly improve indel activity.
