PRL-1 Double Nickase Plasmid (m) | sc-422499-NIC | 20 µg | $410.00 |
Mouse Ptp4a1 encodes PRL-1, a prenylated protein tyrosine phosphatase that localizes to cellular membranes and regulates phosphorylation-dependent signaling linked to cytoskeletal remodeling, cell-cycle progression, and directional migration. PRL-1 activity interfaces with pathways governing focal adhesion dynamics and small GTPase-driven motility programs, influencing how cells respond to extracellular cues. Altered PRL-family phosphatase signaling has been associated with dysregulated proliferation and invasion phenotypes in cancer biology, and PRL-1 is also studied in the context of immune cell trafficking and tissue remodeling. As a result, Ptp4a1 is a useful target for interrogating phosphatase control of signaling networks and cellular plasticity in mouse models.
PRL-1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Ptp4a1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Ptp4a1. 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 Ptp4a1 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 Ptp4a1-disrupted clones.
