Efna5 encodes ephrin-A5, a GPI-anchored ligand for EphA receptor tyrosine kinases that mediates contact-dependent signaling to coordinate cell positioning, boundary formation, and axon guidance during nervous system development. Ephrin-A5–EphA interactions regulate cytoskeletal remodeling and adhesive dynamics through Rho family GTPases, impacting neurite outgrowth, synaptic targeting, and tissue patterning. In mouse models, altered ephrin-A5 signaling has been linked to defects in corticothalamic and retinal axon mapping, hippocampal circuitry, and other neurodevelopmental processes. Dysregulation of Eph/ephrin pathways is also studied in contexts of aberrant cell migration and invasion, making Efna5 a relevant target for mechanistic research in developmental neurobiology and disease-associated signaling.
ephrin-A5 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Efna5 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Efna5. 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 Efna5 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 Efna5-disrupted clones.
