The Double Nickase Plasmid features a U6 promoter for sgRNA expression, a 20 nt targeting sequence, and a gRNA scaffold to guide Cas9n. It includes a CBh promoter for Cas9n (D10A) and puromycin resistance, GFP for transfection verification, and nuclear localization signals (NLS). The 2A peptide allows co-expression of Cas9n and Puro from a single promoter, enabling precise genome editing with reduced off-target effects.

Cas9n Nickase gRNA Plasmid Targeting: Dual gRNA plasmids create single-strand nicks at precise DNA sequences for efficient genome editing using Cas9n Nickase.
This image illustrates the Cas9n Nickase mechanism used for precise genome editing. Two plasmids (Plasmid 1 and Plasmid 2) are shown, each containing a targeted DNA sequence. The system utilizes single-guide RNAs (sgRNA) to direct Cas9n Nickase to specific genomic locations, represented by the blue and pink DNA strands. The sgRNA scaffold aids in guiding Cas9n to the 20 nucleotide (nt) target sequence on the DNA. Cas9n makes single-strand cuts at NCC and NGG sites, enabling precise gene modifications without creating double-strand breaks.

Ky 编码 KY 肽酶(KY peptidase),这是一种在肌肉中富集的蛋白,被认为参与维持骨骼肌完整性和肌小节结构组织,并在肌纤维应激过程中发挥蛋白质稳态调控与结构重塑作用。在小鼠中,KY 肽酶活性与调控肌原纤维维持与周转的通路相关,有助于支持正常的收缩功能并提高对损伤的抵抗力。Ky 功能受损与符合肌营养不良样病理的神经肌肉表型相关,因此是研究肌病机制的有用基因。由此,KY 肽酶也与横纹肌组织中的肌肉退变、再生以及蛋白质质量控制网络研究密切相关。
KY peptidase 双切酶质粒(m)由一对匹配的质粒组成,专为在 mouse 细胞系中对 Ky 位点进行高特异性编辑而设计。每个质粒分别表达Cas9 D10A切口酶和针对Ky内不同DNA链的独特sgRNA。当这两种切口酶被引导至相邻但位于DNA链相反侧的位点时,会产生错位的单链切口,从而共同形成错位双链断裂,这需要两个引导RNA在靶位点上协同发挥作用。由此产生的DNA断裂通过内源性细胞修复途径(最常见的是非同源末端连接(NHEJ))得到修复,从而导致插入或缺失,进而破坏Ky的功能。通过要求双sgRNA在靶位点结合,双切口方法提高了编辑特异性,并为需要对靶向精度进行额外控制的应用提供了互补的CRISPR策略。
