PcoCas12a: A novel CRISPR enzyme from Prevotella copri enhancing TCR-T-cell tumor suppression.

Genome editing technologies have been widely utilized in cell engineering, demonstrating immense potential in cell and gene therapy. However, an optimal gene-editing enzyme for immune cell editing remains unidentified. In this study, we identified a novel gene editing enzyme, termed CRISPR/PcoCas12a, derived from Prevotella copri, which recognizes a 5'-YYN PAM sequence.
