EMP3 encodes epithelial membrane protein 3 (EMP-3), a tetraspan-like membrane glycoprotein implicated in regulation of cell–cell interactions, membrane organization, and signaling at the plasma membrane. In human cells, EMP-3 has been associated with modulation of receptor-driven pathways, including EGFR/PI3K–AKT and MAPK signaling, influencing proliferation, survival, and migratory behaviors. Expression changes and genomic alterations of EMP3 have been reported across multiple tumor types and in neurological contexts, linking it to processes such as differentiation, invasion, and microenvironmental responses. As a surface-associated factor, EMP-3 is frequently studied for its impact on signaling dynamics, trafficking, and downstream transcriptional programs relevant to disease biology.
EMP-3 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the EMP3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within EMP3. 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 EMP3 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 EMP3-disrupted clones.
