MST-4 Double Nickase Plasmid (m) | sc-427699-NIC | 20 µg | $410.00 |
Mouse Stk26 encodes MST-4, a Ste20-like serine/threonine kinase that helps coordinate cytoskeletal remodeling, cell polarity, and stress-responsive signaling through phosphorylation of downstream effectors. MST-4 is commonly linked to MAPK-associated networks and kinase cascades that shape actin dynamics, membrane trafficking, and context-dependent control of proliferation and survival. By modulating these processes, Stk26 activity can influence epithelial organization, cell migration, and responses to inflammatory or environmental cues that are frequently altered in disease-relevant phenotypes. As a result, Stk26/MST-4 is of interest for dissecting kinase-driven regulatory nodes in tissue homeostasis and models of dysregulated growth or barrier function.
MST-4 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Stk26 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Stk26. 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 Stk26 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 Stk26-disrupted clones.
