Epithelial membrane protein 1 (EMP1) is a tetraspan membrane glycoprotein implicated in cell–cell interactions, membrane organization, and regulation of epithelial differentiation programs. In human cells, EMP-1 has been linked to modulation of adhesion and migratory phenotypes and intersects with signaling networks that shape proliferation and stress responses, including MAPK/ERK- and PI3K/AKT-associated outputs. Altered EMP1 expression has been reported across multiple cancers and in inflammatory or fibrotic contexts, supporting its use as a molecular handle to study tumor cell plasticity and tissue remodeling. Experimental interrogation of EMP1 helps clarify how membrane microdomain composition influences downstream signaling and transcriptional states.
EMP-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the EMP1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within EMP1. 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 EMP1 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 EMP1-disrupted clones.
