DCTN1 encodes dynactin 1, the major subunit of the dynactin complex that cooperates with cytoplasmic dynein to drive minus-end–directed microtubule transport. Dynactin 1 supports cargo adaptor engagement, processive motility, and organization of the mitotic spindle, linking it to pathways governing vesicular trafficking, endosome/lysosome positioning, and neuronal axon transport. Through roles in centrosome function, autophagy-lysosome dynamics, and proteostasis, DCTN1 helps maintain cellular homeostasis in highly polarized cells. Genetic disruption of DCTN1 has been associated with neurodegenerative phenotypes including motor neuron and movement disorders, making it a relevant target for mechanistic studies of transport failure and cellular stress responses.
Dynactin 1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the DCTN1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within DCTN1. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt DCTN1 function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of DCTN1-disrupted clones.
