DPYSL3 encodes collapsin response mediator protein 4 (CRMP-4), a cytosolic phosphoprotein that links extracellular guidance cues to cytoskeletal remodeling in neurons and other polarized cells. CRMP-4 participates in semaphorin/neuropilin-plexin signaling and downstream kinase pathways that regulate microtubule dynamics, neurite extension, growth cone collapse, and axon guidance. Outside the nervous system, DPYSL3 has been implicated in cell migration and adhesion programs through coordination of cytoskeletal organization. Altered DPYSL3/CRMP-4 expression and phosphorylation states have been associated with neurodevelopmental and neurodegenerative mechanisms and have also been studied in tumor cell invasiveness and metastatic phenotypes as a context-dependent marker of cellular motility.
CRMP-4 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the DPYSL3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within DPYSL3. 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 DPYSL3 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 DPYSL3-disrupted clones.
