PP2A-Cα Double Nickase Plasmid (h2) | sc-400613-NIC-2 | 20 µg | $410.00 |
PPP2CA encodes the catalytic Cα subunit of protein phosphatase 2A (PP2A), a major serine/threonine phosphatase that forms heterotrimeric complexes with scaffold A and diverse regulatory B subunits to control substrate specificity. PP2A-Cα regulates phosphorylation-dependent signaling across cell-cycle progression, DNA damage responses, and cytoskeletal dynamics, with prominent roles in MAPK, PI3K/AKT, and Wnt/β-catenin pathway modulation. Through coordinated dephosphorylation of key kinases and structural proteins, PPP2CA helps maintain proteostasis and checkpoint fidelity. Dysregulated PP2A activity and altered PPP2CA function have been associated with aberrant phosphorylation networks observed in multiple cancers and neurodegenerative disease contexts, supporting its use as a mechanistic node in signaling studies.
PP2A-Cα Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the PPP2CA locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within PPP2CA. 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 PPP2CA 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 PPP2CA-disrupted clones.
