VAC14 Double Nickase Plasmid (h) | sc-408584-NIC | 20 µg | $410.00 |
VAC14 encodes a scaffold component of the PIKfyve–FIG4–VAC14 complex that regulates phosphoinositide metabolism, particularly the interconversion of PI(3)P and PI(3,5)P2 on endolysosomal membranes. Through control of PI(3,5)P2 homeostasis, VAC14 supports endosome maturation, lysosome function, autophagic flux, and membrane trafficking events that maintain cellular proteostasis. Disruption of VAC14-dependent signaling perturbs vacuole/lysosome morphology and stress responses in neurons and other cell types, linking this pathway to neurodegenerative and neurodevelopmental phenotypes reported for defects in the PI(3,5)P2 regulatory axis. As a result, VAC14 is widely studied in models of endolysosomal dysfunction, axonal maintenance, and cellular responses to nutrient and osmotic stress.
VAC14 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the VAC14 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within VAC14. 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 VAC14 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 VAC14-disrupted clones.
