ITGAE encodes integrin αE (CD103), which heterodimerizes with integrin β7 to form the αEβ7 adhesion receptor that binds E-cadherin and supports retention of lymphocytes within epithelial tissues. This receptor participates in integrin outside-in signaling that coordinates cytoskeletal remodeling, cell migration, and immune synapse dynamics, linking to pathways involving focal adhesion kinases and downstream MAPK and PI3K signaling. CD103 is a hallmark of tissue-resident memory T cells and subsets of dendritic cells, shaping mucosal immune surveillance and epithelial barrier interactions. Altered ITGAE expression and CD103-positive immune infiltrates are widely studied in chronic inflammatory settings and in tumor immune microenvironments, where they inform mechanisms of immune cell localization and function.
Integrin αE/ITGAE/CD103 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ITGAE locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ITGAE. 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 ITGAE 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 ITGAE-disrupted clones.
