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.

Adgrg1 编码黏附型 G 蛋白偶联受体 GPR56(ADGRG1)。该膜受体可将细胞外基质信号与细胞内信号转导相整合,从而调控细胞黏附、迁移与极性。GPR56 可被加工为 N 端与 C 端片段,并可与异源三聚体 G 蛋白偶联,进而影响与细胞骨架动力学、机械力转导及发育模式建立相关的信号通路。在小鼠研究体系中,Adgrg1 常用于研究神经元与胶质细胞发育以及免疫细胞行为,其中由受体介导的黏附与运动能力是决定组织结构的重要因素。GPR56 活性失调与神经发育及髓鞘形成相关表型有关,并常在细胞—基质相互作用改变参与疾病相关生物学的研究背景下被重点考察。
