The CRISPR prime editor PE2 consists of a Streptococcus pyogenes Cas9 nickase (nSpCas9) fused at its C-terminus to a Moloney murine leukemia virus reverse transcriptase (MMLV-RT). Here we show that separated nSpCas9 and MMLV-RT proteins function as efficiently as intact PE2 in human cells. We use this Split-PE system to rapidly identify and engineer more compact prime editor architectures that also broaden the types of RTs used for prime editing.

具有紧凑、不受束缚的逆转录酶的工程化 CRISPR prime 编辑器

CRISPR 主编辑器 PE2 由C 端与莫洛尼鼠白血病病毒逆转录酶 (MMLV-RT) 融合的化脓性链球菌Cas9 切口酶 (nSpCas9) 组成。在这里,我们展示了分离的 nSpCas9 和 MMLV-RT 蛋白在人类细胞中与完整的 PE2 一样有效地发挥作用。我们使用这个 Split-PE 系统来快速识别和设计更紧凑的 Prime 编辑器架构,这也拓宽了用于 Prime 编辑的 RT 类型。
