DOCK 8 Double Nickase Plasmid (h) | sc-401727-NIC | 20 µg | $410.00 |
DOCK8 encodes dedicator of cytokinesis 8, an atypical guanine nucleotide exchange factor that regulates Rho family GTPases to coordinate actin cytoskeleton remodeling, cell polarity, and signal integration downstream of immune receptors. DOCK8 supports lymphocyte migration, immune synapse formation, and survival, linking cytoskeletal dynamics with pathways controlling adhesion and vesicular trafficking. Loss-of-function variants disrupt cytoskeletal control in hematopoietic cells and are associated with primary immunodeficiency phenotypes characterized by impaired antiviral responses and dysregulated immune homeostasis. As a signaling node connecting receptor inputs to actin-dependent processes, DOCK8 is widely studied in leukocyte biology, host–pathogen interactions, and immune cell development.
DOCK 8 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the DOCK8 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within DOCK8. 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 DOCK8 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 DOCK8-disrupted clones.
