CRMP1 encodes collapsin response mediator protein 1 (CRMP-1), a cytosolic phosphoprotein that links extracellular guidance cues to cytoskeletal remodeling. CRMP-1 participates in semaphorin/plexin signaling and coordinates microtubule and actin dynamics to regulate neurite outgrowth, growth cone collapse, and neuronal polarity. Through interactions with tubulin-associated complexes and kinase pathways, including CDK5 and GSK3β-dependent phosphorylation cascades, CRMP-1 influences axon guidance and synaptic connectivity. Dysregulation of CRMP-1 has been associated with altered neuronal development and has been studied in the context of neurodevelopmental and neurodegenerative phenotypes, as well as changes in cell migration programs in non-neuronal systems.
CRMP-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CRMP1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CRMP1. 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 CRMP1 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 CRMP1-disrupted clones.
